SHOOT-THRU-HULL PREPARATION 
Hulls With Floatation Materials 
The transducer installation inside a fiberglass hull must be in an area 
that does not have air bubbles in the resin or separated fiberglass 
layers. The sonar signal must pass through solid fiberglass. A 
successful transducer installation can be made on hulls with flotation 
materials (such as plywood, balsa wood or foam) between layers of 
fiberglass if the material is removed from the chosen area. 
 
 
Use epoxy to place the transducer in a solid portion of the hull. 
For example, some (but not all) manufacturers use a layer of fiberglass, 
then a core of balsa wood, finishing with an outer layer of fiberglass. 
Removing the inner layer of fiberglass and the balsa wood core exposes 
the outer layer of fiberglass. The transducer can then be epoxied 
directly to the outer layer of fiberglass. After the epoxy cures for 24 
hours, fill the remaining space with polyester resin. When the job is 
finished, the hull is watertight and structurally sound. Remember, the 
sonar signal must pass through solid fiberglass. Any air bubbles in the 
fiberglass or the epoxy will reduce or eliminate the sonar signals. 
WARNING: 
Do not remove any material from your inner hull unless 
you know the hull's composition. Careless grinding or 
cutting on your hull can result in damage that could sink 
your boat. Contact your boat dealer or manufacturer to 
confirm your hull specifications. 
Testing Determines Best Location 
Ideally, the shoot-thru transducer should be installed as close to the 
transom as possible, close to the centerline. This will give you the best 
performance during high-speed maneuvers.
