Effective for FRP vessels with single hull layer of 10mm or less.
Look for the best picture location before the fixation by putting adequate water on
the transducer surface and vessel bottom followed by pressing the transducer onto
the vessel bottom.

Make a hole of approx.
φ
23 at the vessel bottom. (Alminum vessels are not
subject to the installation for the risk of corrosion.)

Insert the screw part of transducer into the hole and fix it with 1pc cork washer,
1pc washer, and 1pc nut. (Extra cork washer is for spare.)
Execute the water proof care for the junction part.
For tilted hull, use a block etc to face directly to the vessel bottom.
Keep the inclination of transducer surface
