Convex bottom: Place two straightedges under the bottom
parallel to the boat’s centerline. When placed on the straight-
edges and pressed against the transom, the template will
have the right position.
Fix the template on the transom with tape.
Convcave bottom: Place one straightedge at the
interceptor center and use one end of the
template to find its right center position.

2 PREPARE THE TRANSOM
ENSURE A FLAT SURFACE FOR EACH INTERCEPTOR
DRILLING TEMPLATE
The transom must be relatively flat where the Interceptors are mounted to
ensure that they work properly.
Start mounting the Interceptors as far outward as possible, although well
inside the transom. Continue inwards when installing multiple Interceptors.
