Mounting Guidelines
Depth Transducers
•
The main source of the vessel generated noise is the propeller.
•
The deeper the transducer projects the lower the risk of
aerated water.
•
On displacement hulls place the transducer 1/3 aft along
waterline.
•
Avoid locations near the keel or bow due to aeration.
•
Mount the transducer on the side of the hull where the
propeller is moving downward.
•
On sailboats mount forward of the fin keel, with minimum
dead rise.
•
On planing vessels mount aft near the keel to insure water
contact at high speed.
•
On I/O’s mount close to the engine.
•
On inboards mount well ahead of the propeller.
•
On higher speed vessels (+27 knots) mount in known good
locations.
•
Do not mount near water discharge or behind struts or fittings,
which will create turbulence.
•
For dead rise greater than 10 degrees a fairing is
recommended.
Speed Transducer
•
On sailboats the sensor should be mounted close to the
centerline and 12 to 24” ahead of the keel.
•
On displacement vessels the paddlewheel should be mounted
well aft so the sensor is always in contact with the water.
•
Do not position the paddlewheel directly ahead of a depth
transducer.
•
Do not locate the speed sensor behind struts or thru-hull
fittings.
