Selecting Steering Cables

and Remote Control Cables

Refer to “Quicksilver Accessories Guide” to deter-

mine correct length of steering cables and remote

control cables.

IMPORTANT: Steering cables and remote control

cables must be the correct length. Sharp bends

on too-short cables result in “kinks;” too-long

cables require unnecessary bends and/or loops.

Both conditions place extra stress on the cables.

Installing Outboard on

Transom

Determining Recommended

Outboard Mounting Height

Long drive shaft housing models are designed to op-

erate on boats that have a 20 inch transom (51 cm).

X-Long drive shaft housing models are designed to

operate on boats that have a 25 inch transom (64 cm).

For best all-around boating performance, it is recom-

mended that the outboard be mounted with the

anti-ventilation plate flush with the boat bottom.

Locating Centerline of Boat Transom

Locate (and mark with pencil) vertical centerline (a)

of boat transom.

a - Centerline of Transom

NOTE: Dimensions “A” = “B” and “C” = “D”.

Drilling Outboard Mounting Holes

IMPORTANT: Before drilling any mounting holes,

carefully read “Determining Recommended Out-

board Mounting Height,” preceding. There is a 3/4

in. (19 mm) difference between outboard mount-

ing holes in transom brackets.

!WARNING

DO NOT, under any circumstances, allow upper

outboard mounting bolts to be closer than 1 in.

(25.4 mm) from top of boat transom. Upper

mounting bolts must never be installed thru

shims.

NOTE: When drilling into a fiberglass boat, place

masking tape directly onto boat where mounting

holes will be drilled to help prevent fiberglass from

chipping.

IMPORTANT: When using “Transom Drilling Fix-

ture” (part number 91-98234A2), use drill guide

holes marked “A” when drilling outboard mount-

ing holes.

a - Centerline of Transom

b - Transom Drilling Fixture (91-98234A2)

1. Use a 17/32 in. (13.5 mm) diameter drill bit to drill

4 mounting holes perpendicular to and thru tran-

som.

Lifting Outboard

!WARNING

Make sure lifting ring is threaded on flywheel a

minimum of 5 turns and that hoist has a maximum

lift capacity over 500 lbs. (227 kg) BEFORE lifting

outboard.

Remove top cowl from outboard. Thread lifting ring

(a) on flywheel a minimum of 5 turns.

a - Lifting Ring (91-90455)

Connect hoist [maximum lifting capacity over 500 lbs.

(227 kg)] to lifting ring and lift outboard onto boat tran-

som.

Securing Outboard to Boat Transom

IMPORTANT: If boat is equipped with thru tilt tube

steering, steering cable end must be installed

into tilt tube of outboard before securing out-

board to transom. Refer to “Steering Cable and

Steering Link Rod Installation” following.

Position outboard on boat transom to align mounting

holes in transom brackets with those drilled in boat

that will place the outboard at the recommended

mounting height (refer to “Determining Recom-

mended Outboard Mounting Height,” preceding).

CAUTION

Marine sealer must be used on shanks of mount-

ing bolts (not threads) to make a water-tight in-

stallation.

IMPORTANT: DO NOT use an impact driver when

tightening transom mounting bolts.

Apply marine sealer to shanks of mounting bolts (not

threads). Secure outboard to transom using four (4)

bolts, flat washers and locknuts, as shown. Be sure

installation is water-tight.

!WARNING

Before operating, outboard(s) MUST BE SE-

CURED to boat transom with four 1/2 in. diameter

bolts, flat washers and locknuts (supplied) as fol-

lows: two (2) bolts must be installed thru upper

mounting holes and two (2) bolts thru lower

mounting holes. Installation must be water-tight

and outboard should be checked for tightness on

transom during operation. Failure to bolt out-

board to transom as described may result in dam-

age to the boat and/or loss of outboard and possi-

ble injury to occupants of boat.

Ride Guide Steering Cable/

Attaching Kit Installation

NOTE: These instructions are for single cable-single

outboard installations. Instructions for mounting dual

engines are included with the applicable dual engine

attaching kit. Refer to “Quicksilver Accessories

Guide” to determine correct kit.

Refer to “Quicksilver Accessories Guide” to deter-

mine correct length of steering cable.

IMPORTANT: Steering cable must be correct

length. Sharp bends on too-short of a cable result

in “kinks;” too-long of a cable requires unneces-

sary bends and/or loops. Both conditions place

extra stress on the cable.

Install steering mount and steering wheel in accor-

dance with installation instructions that accompany

each.

Installing Ride Guide Steering Cable

To The Outboard

IMPORTANT: Before installing steering cable in

tilt tube, lubricate entire cable end with Quicksil-

ver 2-4-C Marine Lubricant.

NOTE: Ride Guide steering cable is lubricated at the

factory and requires no additional lubrication at initial

installation.

1. Lubricate seal (a) inside of outboard tilt tube and

entire cable end (b) with Quicksilver 2-4-C Marine

Lubricant.

2. Insert steering cable end thru outboard tilt tube

and secure steering cable to tilt tube with steering

cable attaching nut (c), as shown. Torque nut to

35 lb. ft. (47.5 N·m).

Steering Link Rod Installation

IMPORTANT: The steering link rod that connects

the steering cable to the engine must be fastened

using special washer head bolt (“a” – Part Num-

ber 10-14000) and self locking nuts (“b” & “c” –

Part Number 11-34863). These locknuts must

never be replaced with common nuts (non lock-

ing) as they will work loose and vibrate off freeing

the link rod to disengage.

IMPORTANT: Disengagement of a steering link

rod can result in the boat taking a full, sudden,

sharp turn. This potentially violent action can

cause occupants to be thrown overboard expos-

ing them to serious injury or death.

3. Assemble steering link rod to steering cable with

two flat washers (d) and nylon insert locknut (“b”

– Part Number 11-34863). Tighten locknut (b) un-

til it seats, then back nut off 1/4 turn.

4. Assemble steering link rod to engine with special

washer head bolt (“a” – Part Number 10-14000)

and nylon insert locknut (“c” – Part Number

11-34863). First torque bolt (a) to 20 lb. ft. (27.1

N·m), then torque locknut (c) to 20 lb. ft. (27.1

N·m). Install access hole plug in bottom cowl.

a - Head Bolt

b - Locknut

c - Nylon Insert Locknut

d - Flat Washers

e - Access Hole Plug

f - Access Hole (located in bottom cowl)

!WARNING

After installation is complete (and before operat-

ing outboard), check that boat will turn right when

steering wheel is turned right and that boat will

turn left when steering wheel is turned left. Check

steering thru full range (left and right) and at all tilt

angles to assure interference-free movement.

Lubrication

Lubrication and maintenance inspection of the steer-

ing system is the owners responsibility. It must be per-

formed every 60 days in fresh water or 30 days in salt

water.

Refer to operators manual for correct lubrication and

maintenance procedure.

Remote Control Installation

Refer to “Quicksilver Accessories Guide” to deter-

mine correct length of remote control cables.

IMPORTANT: Remote control cables must be cor-

rect length. Sharp bends on too-short cables re-

sult in “kinks;” too-long cables require unneces-

sary bends and/or loops. Both conditions place

extra stress on the cables.

IMPORTANT: Install control cables to remote con-

trol and mount remote control BEFORE attaching

control cables to engine. Refer to installation in-

structions included with remote control.

Shift and Throttle Cable

Installation to the Outboard

Install the shift cable and throttle cable into the remote

control and mount the remote control following

instructions which are provided with remote control.

NOTE: Install the shift cable before the throttle cable.

The shift cable is the first cable to move when the re-

mote control handle is actuated.

Shift Cable Installation

1. Position the remote control handle into neutral

detent.

2. Manually shift engine (move shift actuator “a”)

into neutral position. The propeller shaft can ro-

tate in either direction.

3. Slide shift actuator (a) toward the rear of engine

(reverse gear) until resistance is felt. Measure the

distance between mounting stud and barrel re-

tainer. Push the cable end in (towards cable bar-

rel) until resistance is felt. Adjust the cable barrel

to obtain the proper distance.

washer (e) and locknut (d). Tighten locknut

against the nylon washer, then back-off the lock-

nut 1/4 turn. Lock cable barrel (c) in barrel retainer

(b) with retainer latch (f).

5. Check shift cable adjustments as follows:

a. With remote control in forward the propshaft

should lock solidly in gear. If it does not, adjust

the cable barrel closer to the cable end guide.

b. Shift remote control into neutral. The prop-

shaft should turn freely without drag. If not,

adjust the barrel away from the cable end

guide. Repeat steps a and b.

c. Shift remote control into reverse while turning

propeller. The propshaft should lock solidly in

gear. If not, adjust the barrel away from the

cable end guide. Repeat steps a thru c.

d. Return remote control handle to neutral. The

propeller should turn freely without drag. If

not, adjust the barrel closer to the cable end

guide. Repeat steps a thru d.

Throttle Cable Installation

NOTE: Attach SHIFT CABLE to engine prior to at-

taching THROTTLE CABLE.

1. Position remote control handle in neutral detent.

2. Position engine throttle lever against idle stop.

3. Measure distance between throttle barrel retainer

(a) and throttle actuator stud (b) (center-to-cen-

ter). Add 1/8 in. (3.18 mm) for preload.

4. Adjust cable barrel (c) to attain the same distance

between barrel and hole in throttle cable end

guide (center-to-center) as measured in step 3.

5. Place the throttle cable barrel into barrel retainer

and the cable end on the cable mounting stud.

Fasten throttle cable to the mounting stud with ny-

lon washer (e) and locknut (d). Tighten locknut

against the nylon washer, then back-off the lock

nut 1/4 turn. Lock cable barrel (c) in barrel retainer

(a) with retainer latch (g).

6. Check throttle cable adjustment as follows:

a. Advance remote control to wide open throttle

and bring back to neutral.

b. Manually push tower shaft (f) towards idle

stop. If tower shaft moves toward stop, adjust

cable barrel away from cable end guide. Re-

peat steps a and b.

Propeller Selection

Refer to “Quicksilver Accessory Guide” for a com-

plete list of available propellers.

For best all around performance from your outboard/

boat combination, select a propeller that allows the

engine to operate in the upper half of the recom-

mended full throttle RPM range with the boat normally

loaded (refer to Specifications in the Operators Man-

ual). This RPM range allows for better acceleration

while maintaining maximum boat speed.

If changing conditions cause the RPM to drop below

the recommended range (such as warmer, more

humid weather, operation at higher elevations, in-

creased boat load or a dirty boat bottom/gear case)

this may require a propeller change or cleaning to

maintain performance and ensure the outboard’s

durability.

Check full-throttle RPM using an accurate tachome-

ter with the engine trimmed out to a balanced steering

condition (steering effort equal in both directions)

without causing the propeller to “break loose.”

Propeller Installation

!WARNING

When the propeller shaft is rotated and the en-

gine is in gear, there is the possibility for the en-

gine to crank over and start. To prevent this type

of accidental engine starting and possible seri-

ous injury caused from being struck by a rotating

propeller, always set the remote control into neu-

tral and remove spark plug leads when you are

servicing the propeller.

CAUTION

If the propeller moves forward-and-aft on the pro-

peller shaft (is loose), retighten the propeller nut.

Operation with a loose propeller could cause

damage to the thrust hub and gear housing dur-

ing acceleration, deceleration or when shifting

gears.

IMPORTANT: To assure that the propeller remains

secure on the shaft during the season, periodical-

ly check propeller locknut for tightness.

To prevent the propeller hub from corroding and seiz-

ing to the propeller shaft, especially in salt water, al-

ways apply a coat of Quicksilver Anti-Corrosion

Grease to the entire shaft at recommended mainte-

nance intervals and each time the propeller is re-

moved.

1. Shift remote control into neutral position.

2. Remove leads from spark plugs to prevent engine

from starting.

- 10 -

3. Apply Quicksilver Anti-Corrosion Grease to entire

shaft.

4. Install thrust washer (a), propeller (b), propeller

nut retainer (c), and propeller nut (d) onto the

shaft.

5. Place a block of wood between gear case and

propeller and torque propeller locknut to 55 lb. ft.

(75 N·m), aligning tabs of washer with flat grooves

of propeller hub.

6. Secure propeller nut by bending three of the tabs

into the thrust hub grooves.

Power Trim System

General Information

The power trim system is filled at the manufacturer

and is ready for use.

Trim outboard through entire trim and tilt range sever-

al times to remove any air from the system.

The trim system is pressurized and is not externally

vented.

Power Trim Operation

With most boats, operating around the middle of the

“trim” range will give satisfactory results. However, to

take full advantage of the trimming capability there

may be times when you choose to trim your outboard

all the way in or out. Along with an improvement in

some performance aspects comes a greater respon-

sibility for the operator, and this is being aware of

some potential control hazards. The most significant

control hazard is a pull or “torque” that can be felt on

the steering wheel or tiller handle. This steering

torque results from the outboard being trimmed so

that the propeller shaft is not parallel to the water sur-

face.

IMPORTANT: Avoid possible serious injury or

death. When the outboard is trimmed in or out be-

yond a neutral steering condition, a pull on the

steering wheel or tiller handle in either direction

may result. Failure to keep a continuous firm grip

on the steering wheel or tiller handle when this

condition exists can result in loss of boat control

as the outboard can turn freely. The boat can now

“spin out” or go into a very tight maximum turn

which, if unexpected, can result in occupants be-

ing thrown within the boat or out of the boat.

Consider the following lists carefully.

TRIMMING IN OR DOWN CAN:

1. Lower the bow.

2. Result in quicker planing off, especially with a

heavy load or a stern heavy boat.

3. Generally improve the ride in choppy water.

4. Increase steering torque or pull to the right (with

the normal right hand rotation propeller).

5. In excess, lower the bow of some boats to a point

where they begin to plow with their bow in the wa-

ter while on plane. This can result in an unex-

pected turn in either direction called “bow steering”

or “over steering” if any turn is attempted or if a sig-

nificant wave is encountered.

!WARNING

Avoid possible serious injury or death. Adjust

outboard to an intermediate trim position as soon

as boat is on plane to avoid possible ejection due

to boat spin-out. Do not attempt to turn boat when

on plane if outboard is trimmed extremely in or

down and there is a pull on the steering wheel or

tiller handle.

TRIMMING OUT OR UP CAN:

1. Lift the bow higher out of the water.

2. Generally increase top speed.

3. Increase clearance over submerged objects or a

shallow bottom.

4. Increase steering torque or pull to the left at a nor-

mal installation height (with the normal right hand

rotation propeller).

5. In excess, cause boat “porpoising” (bouncing) or

propeller ventilation.

6. Cause engine overheating if any water intake

holes are above the water line.

- 11 -

Trim “In” Angle Adjustment (Models

With Power Trim)

Some outboard boats, particularly some bass boats,

are built with a greater than normal transom angle

which will allow the outboard to be trimmed further “in”

or “under”. This greater trim “under” capability is de-

sirable to improve acceleration, reduce the angle and

time spend in a bow high boat attitude during planing

off, and in some cases, may be necessary to plane off

a boat with aft live wells, given the variety of available

propellers and height range of engine installations.

However, once on plane, the engine should be

trimmed to a more intermediate position to a avoid a

bow-down planing condition called “plowing”. Plow-

ing can cause “bow steering” or “over steering” and

inefficiently consumes horsepower. In this condition,

if attempting a turn or encountering a diagonal, mod-

erate wake, a more abrupt turn than intended may re-

sult.

In rare circumstances, the owner may decide to limit

the trim under. This can be accomplished by purchas-

ing a stainless steel tilt pin (P/N 17-49930A1) and in-

serting it through whatever pin hole is desired. The

non-stainless steel shipping bolt should not be used

in this application other than on a temporary basis.

IMPORTANT: Avoid possible serious injury or

death. Adjust outboard to an intermediate trim

position as soon as boat is on plane to avoid pos-

sible ejection due to boat spin-out. Do not at-

tempt to turn boat when on plane if outboard is

trimmed extremely in or down and there is a pull

on the steering wheel or tiller handle.

a - Stainless Steel Tilt Pin (P/N 17-49930A1)

Checking Power Trim Fluid Level

1. Tilt outboard to the full up position and engage the

tilt support lever.

2. Remove fill cap and check fluid level. The fluid

level should be even with the bottom of the fill

hole. If necessary, add Quicksilver Power Trim &

Steering Fluid or automotive transmission fluid

(ATF) Type F, FA or Dexron II.

a - Fill Cap

Tilt Pin Adjustment (Models

Without Power Trim)

!WARNING

DO NOT operate boat without the tilt pin installed.

Failure to install tilt pin could result in outboard

kicking up when operated in reverse causing se-

rious injury, death, or property damage.

Place tilt pin in desired hole in the transom bracket so

the outboard will run perpendicular to the water when

the boat is running at full speed. This allows the boat

to be driven parallel to the water.

a - Tilt Pin

Consider the following lists carefully when adjusting

the tilt pin.

- 12 -

PLACING TILT PIN IN LOWER HOLES CAN:

1. Lower the bow.

2. Result in quicker planing off, especially with a

heavy load or a stern heavy boat.

3. Generally improve the ride in choppy water.

4. Increase steering torque or pull to the right (with

the normal right hand rotation propeller).

5. In excess, lower the bow of some boats to a point

where they begin to plow with their bow in the wa-

ter while on plane. This can result in an unex-

pected turn in either direction called “bow steer-

ing” or “over steering” if any turn is attempted or

if a significant wave is encountered.

PLACING TILT PIN IN UPPER HOLES CAN:

1. Lift the bow out of the water.

2. Generally increase top speed.

3. Increase clearance over submerged objects or a

shallow bottom.

4. Increase steering torque or pull to the left at a nor-

mal installation height (with the normal right hand

rotation propeller).

5. In excess, cause boat “porpoising” (bouncing) or

propeller ventilation.

Trim Tab Adjustment

Propeller steering torque will cause your boat to pull

in one direction. This steering torque is a normal thing

that results from your outboard not being trimmed so

the propeller shaft is parallel to the water surface. The

trim tab can help to compensate for this steering

torque in many cases and can be adjusted within lim-

its to reduce any unequal steering effort.

NOTE: Trim tab adjustment will have little effect re-

ducing steering torque if the outboard is installed with

the anti-ventilation plate approximately 2 inches

(50mm) or more above the boat bottom.

MODELS WITHOUT POWER TRIM

Operate your boat at normal cruising speed trimmed

to desired position by installing the “tilt pin” in the de-

sired tilt pin hole. Turn your boat left and right and note

the direction the boat turns more easily.

If adjustment is necessary, loosen trim tab bolt and

make small adjustments at a time. If the boat turns

more easily to the left, move the trailing edge of trim

tab to the left. If the boat turns more easily to the right

move the trailing edge of trim tab to the right. Retigh-

ten bolt and retest.

MODELS WITH POWER TRIM

Operate your boat at normal cruising speed, trimmed

to desired position. Turn your boat left and right and

note the direction the boat turns more easily.

If adjustment is necessary, loosen trim tab bolt and

make small adjustments at a time. If the boat turns

more easily to the left, move the trailing edge of trim

tab to the left. If the boat turns more easily to the right

move the trailing edge of trim tab to the right. Retigh-

ten bolt and retest.

Boat Performance

Test Instructions

IMPORTANT: A tight grip on the steering wheel/

tiller handle is always advisable when accelerat-

ing, decelerating, or when trimming the boat. On

models with Power Trim, upon reaching cruising

speed, the outboard should be trimmed to obtain

a balanced steering condition. While trimming,

steering loads will vary and will pull in one

direction until a balanced steering condition is

obtained. If the outboard is trimmed past the

balanced steering condition, the steering wheel/

tiller handle then will have a tendency to pull in

the opposite direction. Excessive trimming past

the balanced steering position will result in

increased steering loads, and, in most boat

applications, a decrease in performance.

CAUTION

When trimming a boat with dual outboards, both

outboards should be at approximately the same

tilt angle and be tilted out (up) simultaneously (to

prevent boat from pitching side-to-side) until de-

sired boat attitude is achieved. Outboards can

then be trimmed individually to precisely adjust

boat trim angle and pitch.

1. With boat in water, trim the outboard(s) (trim but-

ton in remote control handle) so that the decal on

the side cowl is horizontal. This is a typical setting

that should give reasonable acceleration and top

speed.

2. Go for a short familiarization ride at various

throttle and trim settings BEFORE starting test-

ing.

3. When making either top speed or acceleration

runs, best accuracy will be obtained by running

with or against any wind. Side winds require driv-

ing in a constant turn to keep the boat running

straight-ahead. If winds are 10 MPH (16 km/hr) or

greater, it is suggested that all acceleration runs

be made down wind.

4. The top speed WOT (wide open throttle) test

should be done with the boat normally loaded (to

duplicate actual running conditions). Operate

boat in gear at WOT and check RPM. Engine

RPM must be within the recommended full

throttle RPM range (listed in Operation and Main-

tenance Manual).

NOTE: When performing an acceleration test, it is

recommended that a stop watch be used to improve

testing accuracy. A wrist watch with a second hand

may be substituted.

5. An acceleration test can also be performed if de-

sired. Start the test with boat motionless in the wa-

ter and outboard in neutral. A stop watch should

be started as the throttle is quickly pushed to

WOT (wide open throttle). Stop the watch as the

speedometer needle sweeps past 20 MPH (32

km/hr). Several runs should be made to assure a

good average.

6. Prop “break loose” (sudden high RPM), if not ex-

cessive, in some cases can be beneficial during

acceleration. If undesirable “break loose” occurs,

it can be decreased by trimming the outboard fur-

ther under. If it remains excessive with all similar

propellers, the outboard must be lowered.

7. It is suggested that all applicable data be re-

corded on a chart and retained for future refer-

ence.

8. After several propellers of different pitch and/or

design have been tried, select one that best ser-

vices the general purpose of the boat. The se-

lected propeller should enable the engine to oper-

ate within its recommended full throttle RPM

range, without excessive propeller “break loose”

during acceleration or turns. A second propeller,

which would make both a suitable spare or a spe-

cial purpose alternate, might also be desirable.

NOTE: A higher pitch often gives better top speed,

but the next lower pitch gives adequate top speed

with much better acceleration.
