NOTICE

HEED ALL WARNINGS AND CAUTIONS AS SET FORTH HEREIN.

THEY HAVE BEEN INCLUDED FOR YOUR SAFETY AND MUST BE

READ CAREFULLY. NEGLIGENCE IN OBSERVING SUCH WARNINGS

AND CAUTIONS COULD RESULT IN SEVERE INJURY OR DEATH.

EMERGENCY STOP SWITCH

A safety switch in the steermg Handle or in the Remote Control Box will cut off

the engine when the safety switch line is pulled out. This line connects to the

wrist of the operator, effectively preventing injuries from the propeller if he

falls overboad. We highly recommend use of the safety switch line. since it can

save the life of the operator if bad things come to worse. However, we would

also like to point out the drawbacks of the switch to the operator. Accidental

activation of the swtch (such as the line being pulled in heavy seas), could

cause passengers to lose their balance, fall overboard, and could result in loss of

power in heavey sears. strong currents or high winds. Loss of control while

mooring is another potential hazard

To prevent such hazardous situation, the line is curled and will extend to a full

I ,300mm.

WARNING

As the operator/driver of the boat, you are responsible for the safety of those

aboard, other crafts around you and that local boating regulations are followed.

As such you should possess thorough knowledge of correct operation of the

boat, its accessories and the engine. Thus. to learn about correct operation and

maintenance of the engine, please read through this manual carefully.

WARNING

It is very difficult for a person standing or floating in the water to take evasive

action should he see a power boat heading in his direction. even at a slow

speed. Therefore, it is strongly recommended that when your boat is in the

immediate vicinity of people in the water, the engine be shifted to neutral and

shut off.

SERIOUS INJURY IS LIKELY IF CONTACT IS MADE WITH A PERSON

IN THE WATER BY A MOVING BOAT, GEAR HOUSING, PROPELLER,

OR ANY SOLID DEVICE RIGIDLY ATTACHED TO A BOAT OR

GEARHOUSING~

all lubrication and maintenance instructions are complied with for safe

operation It is also the operator’s responsibihty to return the unit to the local

dealer for periodic inspection.

the chance for problems and keep overall operating expenses at a minimum.

SERVICING, REPLACEMENT PARTS & LUBRICANT.

WARNING I

The maximum horsepower rating of the engine is indicated on the

CERTIFICATION PLATE on the engine itself. Be sure that the

maximum engine horsepower rating does not exceed that

recommended for your boat. It is very DANGEROUS to operate a

boat with an overpowered engine.

I

WARNING I

Do not operate the engine until it has been securely mounted on the

boat in accordance with the instruction below.

exact center of the stern, and mount

it using a cushioning pad or plate.

engine with the Anti-cavitation Plate at a level 0 - 30mm (0 -

I. I8 in.) below the bottom of the boat. (Fig. 3)

CAUTION I

I

Overheating may occur if the Anti-cavitation Plate is at a level higher than the

bottom of the boat, as a result of air sucking. I

W If the hight difference exceeds 0 - 30mm (0 - I.18 in.) engine power

perfromance is likely to be reduced as a result of mcreased water resistance

to the gear case assembly.

@Attaching the Stem Bracket

After positioning the Stem Bracket, fix it with clamp screws then drill four

holes in the transom board, matching the holes in the Stern Bracket. Secure

the engine with the supplied bolts (Ml2 x 90mm) and nuts Be sure to use

the washers The small diameter washers go with the bolts and the larger

diameter washers go wit the nuts

15

The mounting holes may be drilled beforehand by referring to the

dtmentional drawing.

NOTE

We recommend that the bolt head

of

the upper bolts face inward while the

nut5 are kept on the outside

of

NOTES

1. Apply sealing agent, such 01 silicon sealer, behveen the bolts and the

transom board holes when tightening the bolt.
