1 General

The log/temp transducer with Valve is an impeller transducer installed through the hull

and designed to meet the requirements of owners of sailing crafts and power boats.

CAUTION: NEVER USE SOLVENTS

Cleaners, fuel, paint, sealants, and other products may contain strong solvents, such as

acetone, which attack many plastics greatly reducing their strength.

1.1 Applications

Plastic housing recommended for fiberglass or metal hulls only. Never install a

plastic housing in a wood hull since swelling of the wood may overstress the plastic

causing a fracture.

Bronze housing recommended for fiberglass or wood hulls only. Never mount a

bronze housing in a metal hull because electrolytic corrosion will occur.

Stainless steel housing recommended for metal hulls to prevent electrolytic

corrosion.

IMPORTANT: Please read these instructions completely before proceeding with

the installation. These instructions supersede any other instructions in your

instrument manual if they differ.

English LOG TH52

Safety goggles

Dust mask

Electric drill with 10mm (3/8") or larger chuck capacity

Drill bit 3mm or 1/8"

Hole saw 51mm or 2" (plastic or bronze housing)

57mm or 2-1/4" (stainless steel housing in a metal hull)

Countersink tool (installing a flush housing)

Sandpaper

Mild household detergent or weak solvent (such as alcohol)

File (installation in a metal hull)

Marine sealant

Additional washer [for aluminum hull less than 6mm (1/4") thick]

Zip-ties

Installation in a cored fiberglass hull (see page 3)

Hole saw for hull interior 60mm or 2-3/8"

Fiberglass cloth and resin or Cylinder, wax, tape, and casting epoxy

1.3 Pre-Installation Test

Connect the sensor to the instrument and spin the paddlewheel. Check for a speed

reading (and the approximate air temperature if applicable). If there is no reading or it is

inaccurate, return the instrument to the place of purchase.

1.4 Antifouling Paint

Marine growth can accumulate rapidly on the sensor’s surface reducing performance

within weeks. Surfaces exposed to salt water must be coated with antifouling paint. Use

water-based or mineral spirits based antifouling paint only. Never use ketone based

paint, since ketones can attack many plastics possibly damaging the sensor. It is

easiest to apply antifouling paint before installing the sensor, but allow sufficient drying

time. Reapply paint every 6 months or at the beginning of each boating season. Paint

the following surfaces (see Figure 1):

Outside wall of the paddlewheel insert below the lower O-ring

Paddlewheel cavity

Paddlewheel

Exterior lip of the housing and valve assembly

Bore of the valve assembly up 30mm (1-1/4")

Blanking plug below the lower O-ring including the exposed end

1.5 Mounting Location

Turbulence-free water must flow over the paddlewheel at all speeds. Choose an

accessible spot inside the vessel. Allow a minimum of 280mm (11") of headroom for

the height of the housing, tightening the nuts, and removing the insert.

LOG TH52 English

10-5

Displacement hull powerboats—Locate amidships near the centerline.

Planing hull powerboats—Mount well aft to insure the sensor is in contact with

the water at high speeds.

Fin keel sailboats—Mount on or as close as possible to the centerline and

forward of the fin keel 300–600mm (1–2').

Full keel sailboats—Locate amidships and away from the keel at the point of

minimum deadrise.

Caution: Do not mount the sensor in an area of turbulence or bubbles: near water

intake or discharge openings; behind strakes, fittings or hull irregularities; or behind

eroding paint (an indication of turbulence).

Caution: Never mount the sensor directly ahead of a depth transducer, since

turbulence generated by the paddlewheel’s rotation will adversely affect the

transducer’s performance, especially at high speeds.

English LOG TH52

10-6

2 Installation

Cored fiberglass hull—Follow separate instructions on page 3.

Hole Drilling

Warning: Always wear safety goggles and a dust mask.

1. Drill a 3 mm or 1/8" pilot hole from inside the hull. If there is a rib, strut or other hull

irregularity near the selected mounting location, drill from the outside.

2. Using the appropriate size hole saw, cut the hole from outside the hull. Flush

housing—Use a countersink tool to create a ―seat‖ in the hull.

3. Sand and clean the area around the hole, inside and outside, to ensure that the

sealant will adhere properly to the hull. If there is any petroleum residue inside the

hull, remove it with either mild household detergent or a weak solvent (alcohol)

before sanding.

Metal hull—Remove all burrs with a file and sandpaper.

2.1 Bedding

Apply a 2mm (1/16") thick layer of marine sealant around the lip of the housing that

contacts the hull and up the sidewall of the housing. The sealant must extend 6mm

(1/4") higher than the combined thickness of the hull, washer(s), and hull nut (see

Figure 2). This will ensure there is sealant in the threads to seal the hull and to hold the

hull nut securely in place.

2.2 Installing

Caution: Never pull, carry, or hold the sensor by the cable as this may sever internal

connections.

1. From outside the hull, push the housing into the mounting hole using a twisting

motion to squeeze out excess sealant (see Figure 2). Align the arrow on the lip of

the housing to point forward toward the bow. If the sensor is not installed on the

centerline, angle the housing slightly toward the centerline to align it with the water

flow.

2. From inside the hull, slide the washer onto the housing. Aluminum hull less than

6mm (1/4") thick—Use an additional rubber, fiberglass, or plastic washer. Never

use bronze since electrolytic corrosion will occur. Never use wood since it will

swell, possibly fracturing the plastic housing.

3. Screw the hull nut in place being sure the notch on the upper rim of the housing

and the corresponding arrow on the lip are still positioned forward toward the bow.

(If your plastic housing has wrenching flats, do not clamp tightly, possibly causing

the housing to fracture.) Hand-tighten only. Do not over tighten. Wood hull—

Allow for the wood to swell.

4. Remove any excess sealant on the outside of the hull to ensure smooth water flow

over the paddlewheel. Warning: The O-rings must be intact and well lubricated to

make a watertight seal.

LOG TH52 English

10-7

5. After the sealant cures, inspect the O-rings on the valve assembly (replace if

necessary) and lubricate them with the silicone lubricant supplied (see Figure 3).

6. Slide the valve assembly into the housing being

sure to engage the key in the notch.

7. Screw the plastic cap nut in place and hand-tighten

only. Do not over tighten.

8. Attach one pull ring to the paddlewheel insert (see

Figure 5). Similarly, attach a pull ring to the blanking

plug.

9. Inspect the O-rings on the paddlewheel insert

(replace if necessary) and lubricate them with the

silicone lubricant supplied.

10. Slide the paddlewheel insert into the housing with

the arrows on the top pointing forward toward the

bow. Seat it into place with a pushing twisting

motion until the keys fit into the notches. The arrows

on the top of the insert, the notch in the housing,

and the arrow on the lip will be aligned. Be careful

not to rotate the housing and disturb the sealant.

11. Attach one safety ring to one end of the retaining

pin. Slide the retaining pin through the valve

assembly and paddlewheel insert. Attach the

second safety ring to the retaining pin (see Figure

2).

Warning: Always attach the safety wire to prevent

English LOG TH52

10-8

the insert from backing out in the unlikely event that

the cap nut fails or is screwed on incorrectly.

12. Attach the safety wire to one eye in the hull nut. Thread the short emergency plug

onto the wire. Lead the wire in a counterclockwise direction and thread it through

one eye in the cap nut. Thread the wire through the eye a second time. Then lead

the wire through the pull ring and the second eye in the cap nut. Twist the wire

securely to itself.

13. Route the cable to the instrument being careful not to tear the cable jacket when

passing it through the bulkhead(s) and other parts of the boat. To reduce electrical

interference, separate the sensor cable from other electrical wiring and the engine.

Coil any excess cable and secure it in place with zip-ties to prevent damage.

14. Refer to the instrument owner’s manual to connect the sensor to the instrument.

2.3 Checking for Leaks

Warning: Never install a thru-hull sensor and leave the boat in the water unchecked for

several days.

When the boat is placed in the water, immediately check around the thru-hull sensor

for leaks. Note that very small leaks may not be readily observed. It is best not to leave

the boat in the water for more than 3 hours before checking it again. If there is a small

leak, there may be considerable bilge water accumulation after 24 hour. If a leak is

observed, repeat ―Bedding‖ and ―Installing‖ on page 2 immediately.

2.4 Installation in a Cored Fiberglass Hull

The core (wood or foam) must be cut and sealed carefully. The core must be protected

from water seepage, and the hull must be reinforced to prevent it from crushing under

the hull nut allowing the housing to become loose. Warning: Always wear safety

goggles and a dust mask.

1. Drill a 3mm or 1/8" pilot hole from inside the hull. If there is a rib, strut, or other hull

irregularity near the selected mounting location, drill from the outside. (If the hole is

LOG TH52 English

10-9

drilled in the wrong location, drill a second hole in a better location. Apply masking

tape to the outside of the hull over the incorrect hole and fill it with epoxy.)

2. Using the 51mm or 2" hole saw, cut the hole from outside the hull through the

outer skin only (see Figure 4).

3. From inside the hull, use the 60mm or 2-3/8" hole saw to cut through the inner skin

and most of the core. The core material can be very soft. Apply only light pressure

to the hole saw after cutting through the inner skin to avoid accidentally cutting the

outer skin.

4. Remove the plug of core material so the inside of the outer skin and the inner core

of the hull are fully exposed. Sand and clean the inner skin, core, and the outer

skin around the hole. Caution: Completely seal the hull to prevent water seepage

into the core.

5. If you are skilled with fiberglass, saturate a layer of fiberglass cloth with a suitable

resin and lay it inside the hole to seal and strengthen the core. Add layers until the

hole is the correct diameter. Alternatively, a hollow or solid cylinder of the correct

diameter can be coated with wax and taped in place. Fill the gap between the

cylinder and hull with casting epoxy. After the epoxy has set, remove the cylinder.

6. Sand and clean the area around the hole, inside and outside, to ensure that the

sealant will adhere properly to the hull. If there is any petroleum residue inside the

hull, remove it with either mild household detergent or a weak solvent (alcohol)

before sanding.

7. Proceed with ―Bedding‖ and ―Installing‖ on page 2.

3 Operation, Maintenance

3.1 How the Valve Works

The sensor incorporates a self-closing valve which minimizes the flow of water into the

vessel when the paddlewheel insert is removed. The curved flap valve is activated by

both a spring and water pressure. Water pushes the flap valve upward to block the

opening so there is no gush of water into the boat.

WARNING: The valve is not a watertight seal!

Always install the paddlewheel insert or the long blanking plug secured with the

retaining pin, safety rings, and safety wire for a watertight seal.

3.2 Using the Long Blanking Plug

To protect the paddlewheel, use the long blanking plug when the boat will be kept in

salt water for more than a week, the boat will be removed from the water, or aquatic

growth build-up on the paddlewheel is suspected due

to inaccurate readings from the instrument.

Warning: The O-rings must be intact and well lubricated to make a watertight seal.

1. Inspect the O-rings on the long blanking plug (replace if necessary) and lubricate

them with the silicone lubricant supplied or petroleum jelly (Vaseline ® ) (see

Figure 5).

2. Remove the paddlewheel insert from the housing by removing the safety wire, one

safety ring, and the retaining pin.

Do not remove the cap nut (see Figure 2).

3. Grasp the pull ring and remove the paddlewheel insert with a slow pulling motion.

Note: In the unlikely event that the paddlewheel insert cannot be removed, see

―Servicing the Valve Assembly‖ on page 4.

Warning: Always attach the safety wire to prevent the insert from backing out in

the unlikely event that the cap nut fails or is screwed on incorrectly.

4. Slide the long blanking plug into the housing with the arrows on the top pointing

forward toward the bow. Seat it into place with a pushing twisting motion until the

keys fit into the notches (see Figure 5). Secure it with the retaining pin, safety

rings, and safety wire (see Figure 2).

3.3 Servicing the Paddlewheel Insert

Aquatic growth can impede or freeze the paddlewheel’s rotation and must be removed.

Use a stiff brush or putty knife to remove the growth and clean the surface with mild

household detergent. If fouling is severe, push the paddlewheel shaft out using a spare

shaft or a 4D finish nail with a flattened point. Then, lightly wet sand the surface with

fine grade wet/dry paper. The water lubricated paddlewheel bearings have a life of up

to 5 years on low-speed boats [less than 10kn (11MPH)] and 1 year on high-speed

vessels. Paddlewheels can fracture and shafts can bend due to impact with water

borne objects and mishandling in boat yards. O-rings must be free of abrasions and

cuts to ensure a watertight seal. A replacement Paddlewheel Kit 33-113 is available.

LOG TH52 English

10-11

1. Using the new paddlewheel shaft, push the old shaft out about 6mm (1/4"). With

pliers, remove the old shaft (see Figure 5).

2. Place the new paddlewheel in the cavity with the flat side of the blade facing the

same direction as the arrows on the top of the insert.

3. Tap the new shaft into place until the ends are flush with the insert.

4. Install two of the small O-rings.

5. Place the remaining two small O-rings on the long blanking plug.

6. To re-install the paddlewheel insert, see ―Installing‖ steps 9 through 12 in chapter

2.2.

3.4 Servicing the Valve Assembly

Should the valve fail, remove it for servicing. A replacement Paddlewheel & Valve Kit

33-415 is available.

1. Remove the short emergency plug from the safety wire (see Figure 2).

Warning: The O-ring must be intact and well lubricated to make a watertight seal.

2. ‘Inspect (replace if necessary) and lubricate the O-ring with silicone lubricant or

petroleum jelly (Vaseline ® ).

WARNING: When the valve assembly is removed, always insert the short

emergency plug with the cap nut and safety wire for a watertight seal.

3. Unscrew the cap nut. With the short emergency plug ready in one hand, remove

the paddlewheel insert and valve assembly as one unit by pulling upward on the

pull ring. Rapidly insert the short emergency plug to minimize the flow of water into

the boat.

Note: The plug is not secure until the cap nut is in place.

4. To free the cap nut, remove the paddlewheel insert from the valve assembly by

removing one safety ring and the retaining pin. Grasp the insert by the pull ring and

pull slowly upward.

WARNING: If the insert is caught in the valve assembly trapping the cap nut,

TEMPORARILY hold the short emergency plug in place with the safety wire.

Then, separate the insert from the valve assembly. If they cannot be separated

and the sensor must be left unattended, cut the cable [a minimum of 1m (3') from

the insert] to free the cap nut.

Warning: Always use the cap nut and safety wire to secure the short emergency

plug for a watertight seal.

5. Secure the short emergency plug with the cap nut. Hand-tighten only. Do not

overtighten. Re-attach the safety wire.

6. Separate the valve assembly from the paddlewheel insert.

7. Clean, repair, or replace the valve assembly, so the flap valve moves freely and

seats against the valve housing (see Figure 5).

Warning: The O-rings must be intact and well lubricated to make a watertight seal.

English LOG TH52

10-12

8. To reinstall the valve assembly and paddlewheel insert, inspect (replace if

necessary) and lubricate the O-rings on the valve assembly and the paddlewheel

insert with silicone lubricant or petroleum jelly.

9. Remove the safety wire and cap nut from the emergency plug. With the valve

assembly ready in one hand, remove the emergency plug. Rapidly slide the valve

assembly into the housing being sure to engage the key in the notch. Screw the

cap nut in place hand-tightening only. Do not over tighten.

10. Re-install the paddlewheel insert and secure it with the retaining pin and safety

rings. Attach the safety wire to the short emergency plug, the cap nut, and pull ring

(see Figure 2).

2 Installation

Glasfiberbåtar med sandwich skrov—Följ separat instruktion 2.4

Borrning

Varning: Använd alltid skyddshandskar och ansiktsmask.

1. Borra ett 3mm hål från insidan. Om det av olika anledningar inte går att borra från

insidan, borra utifrån.

2. Borra hålet för bordgenomföringen med hålsågen.

3. Slipa av ytan med sandpapper och tvätta sedan för att tätningsmedlet skall fästa

ordentligt. Om ytan är fet eller oljig, tvätta av med milt lösningsmeddel så som

alkohol eller liknande.

Metall skrov—Använd en fil och sandpapper för att avlägsna grader.

2.1 Tätning

Lägg på ett 2mm tjockt lager av marintätning för undervattensbruk på insidan av

flänsen (den sida som ligger mot skrovet) och på bordgenomföringens utsida. Lägg på

tätningsmedlet så att det gör 6mm högre än skrovets tjocklek, packning och mutter

tillsammans. Detta skall göras för att det säkert skall komma tätningsmedel i gängorna

innanför muttern. Det både tätar och låser muttern.

2.2 Montering

Varning: Bär eller lyft aldrig givaren i kabeln då detta kan skada givaren.

1. Tryck in genomföringen från utsidan i en roterande rörelse för att pressa ut

överskottet av tätningsmedlet. (se Figur 2). Set till att pilen på flänsens utsida

pekar framåt mot den punkt där stäven bryter vattnet. Om givaren inte sitter i

mitten skall den då peka lite inåt.

2. Trä på gummipackningen från insidan. Om skrovet är tunnare än 6mm måste en

extra packning av gummi, glasfiber eller plast användas. Använd aldrig brons i

aluminiumbåtar. Undvik även trä då det kan svälla och skada genomföringen.

3. Skruva på muttern från insidan, var noga med att givaren inte vrids utan

fortfarande pekar i rätt riktning. Dra åt muttern endast med handkraft. I träbåtar, se

till att inte dra åt så hårt utan lämna plats för trät att svälla.

4. Ta bort all överbliven tätningsmeddel på skrovets utsida så vattnet kan strömma

fritt och inte störas. Varning: O-ringarna måst vara hela och insmorda med fett för

att täta ordentligt.

När båten sjösatts, kontrollera direkt runt genomföringen om det finns läckor.

Observera att små läckor kan vara svåra att upptäcka. Du bör inte lämna båten mer än

tre timmar innan du kontrollerar igen. Även om det är en liten läcka kan det samlas

mycket vatten i kölsvinet efter 24 timmar. Om du upptäcker läckage, upprepa

proceduren för montage och tätning.

Kärnan (trä eller skum) måste skäras bort och tätas. Kärnan måste tätas mot

vatteninträngning. Skrovet måste också förstärkas så att det inte trycks ihop och

genomföringsmuttern lossnar.. Varning: Använd alltid skyddshandskar och

skyddsmask.

1. Borra ett 3mm hål från insidan. Om det av olika anledningar inte går att borra från

insidan, borra utifrån)

2. Använd en 51mm hålsåg från utsidan men skär endast igenom ytterskrovet. (se

Figur 4).

3. Använd en 60mm hålsåg från utsidan. Skär igenom innerskrovet och det mesta av

kärnan. Kärnan kan vara mycket mjuk så se till att vara lätt på handen.
