Thru-Hull, Retractable with Valve

Temperature or Speed Temp Sensor

Models: HT200, ST850

U.S. Patents: 7,110,908; 7,352,171. UK 2 409 527

Pretest

Connect the sensor to the instrument. Check for the approximate air

temperature. If it has a paddlewheel, spin it and check for a speed

reading. If there is no reading(s) or it is inaccurate, check the connections

and try again. If there is still a problem, return the product to the place of

purchase.

Record the information found on the cable tag for future reference.

Part No._________________Date___________

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 hull only.

Never mount a bronze housing in a metal hull because electrolytic

corrosion will occur.

• Stainless steel housing compatible with all hull materials.

Recommended for aluminum hulls to prevent electrolytic corrosion

provided the stainless steel housing is isolated from the metal hull.

Tools & Materials

Safety goggles

Dust mask

Water-based anti-fouling paint (mandatory in salt water)

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

Drill bit 3mm or 1/8"

Hole saw: 51mm or 2" (plastic or metal housing in non-metal hull)

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 (suitable for below waterline)

Slip-joint pliers (installing a metal housing)

Grommet(s) (some installations)

Cable ties

Installation in a cored fiberglass hull (see page 4)

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

Fiberglass cloth and resin

or Cylinder, wax, tape, and casting epoxy

Mounting Location

CAUTION: Do not mount in an area of turbulence or bubbles near water intake

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

CAUTION: Never mount the speed 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.

Mount side by side.

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.

HT200—The sensor must be in contact with the water at all times.

ST850—Turbulence-free water must flow over the paddlewheel at all boat

speeds.

• Displacement hull powerboats—Locate amidships near the centerline.

• Planing hull powerboats—Mount well aft to ensure the sensor is in

contact with the water at high speeds.

• Fin keel sailboats—Mount on or near 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.

INSTALLATION INSTRUCTIONSOWNER’S GUIDE &

Follow the precautions below for optimal product

performance and to reduce the risk of property

damage, personal injury, and/or death.

WARNING: Always wear safety goggles and a dust

mask when installing.

WARNING: The valve is not a watertight seal! Always

use the insert or the blanking plug secured with the

safety wire for a watertight seal.

WARNING: The O-rings must be intact and well

lubricated to make a watertight seal.

WARNING: Always attach the safety wire to prevent

the sensor insert or blanking plug from backing out in

the unlikely event that the cap nut fails or is screwed

on incorrectly.

WARNING: Immediately check for leaks when the boat

is placed in the water. Do not leave the boat unchecked

for more than three hours. Even a small leak may allow

considerable water to accumulate.

WARNING: Stainless steel housing in a metal hull—

Be sure the washer contacts the hull. Do not tighten

the hull nut with the washer against the isolation

bushing as the housing will not be firmly installed.

CAUTION: Never install a metal housing in a vessel

with a positive ground system.

CAUTION: Never use a fairing with a plastic housing;

the protruding sensor would be vulnerable to damage

from impact.

CAUTION: Never pull, carry, or hold the sensor by its

cable; this may sever internal connections.

CAUTION: Never use solvents. Cleaners, fuel,

sealants, paint, and other products may contain strong

solvents, such as acetone, which attack many

plastics, greatly reducing their strength.

CAUTION: A stainless steel housing must be isolated

from a metal hull to prevent electrolytic corrosion.

IMPORTANT: Please read the instructions completely

before proceeding with the installation. These

instructions supersede any other instructions in your

instrument manual if they differ.
