Installation
Dead-rise
On hulls with dead-rise of 5 or less, the transducer may be mounted directly through the hull. Where
dead-rise is greater than 5, fairing blocks must be used to orient the face of the transducer parallel
with the water surface.
In this case, no fairing block is necessary. To prevent leakage, any gaps between the stem threads
and holes drilled in the hull should be completely filled with waterproof marine sealant. Tighten the
stem nuts securely but do not over tighten. In this situation, install fairing blocks both inside and
outside the hull. Install the transducer with the face aiming straight down. To prevent leakage, any
gaps between the stem threads and holes drilled in the hull should be completely filled with waterproof
marine
sealant. Tighten the stem nuts securely but do not over tighten.
