15-Minute Installation

Required tools: Drill motor, 1/4" (6 mm) drill bit, Phillips-head screwdriver, 7/16" (11 mm) box wrench or

adjustable wrench.

1.Slip each Doel-Fin Hydrofoil over the cavitation plate directly above your propeller. Each foil is labeled with

an arrow, "TOP/TO BOW". Use each foil, carefully placed symmetrically, as a drilling template. Drill both

1/4" (6 mm) holes through the foil. The plate can be drilled from above or below, depending on available

room for the drill motor. In some instances, a right angle drill chuck may be needed.

2.Remove each foil and clean up the plastic and metal shavings. Slip each foil onto the cavitation plate

again and insert fasteners supplied (the nylon locking nuts go on top). Tighten snugly. Do not over tighten.

Sealant is not required although it can be used.
