Eliminates cavitation and improves prop efficiency
The Doel-fin Hydrofoil Stabilizer is designed to allow water to flow over the fins to create lift that compensates for stern weight. It improves rough-water handling, saves you 10%-50% on fuel costs, eliminates cavitation and improves prop efficiency. With the boat planing out easier, the motor doesn't have to work as hard. The Doel-fin Hydrofoil Stabilizer fits all outboards and out-drives, and installs in less than 15 minutes. Mfrs. limited lifetime warranty.

Product goes on easily and quickly. Did not correct the cavitation problem but does prevent bow rise when accelerating.

This unit was perfect for my boat. The 60HP 4 stroke motor is a little doggy out of the hole. After installing Doel-fin the boat pops out of the hole very fast!!! Boat also seems to run alot smoother through the water. Great product!!!

The Dole-fin has helped my 23 foot Pontoon boat preform much better. The boat is heavy in the aft section with the motor, fuel tank and battery box. The Doel-fin helps greatly, getting the boat on plane faster and maintaining plane at lower speeds. I noticed the difference immediatly.

I have a 115 hp Mercury Outboard. Most of your installation pictures show the back edges of the fins extendinding pass the rear of the cavitation plate. Is this where I should mount the fins or should they be mounted futher forward?
