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.
Rated 5 out of 5 by Eaubes This works
I was very skeptical about this product, but the price was low and I decided to give it a shot. I have a tracker pro 165 with a 25 HP motor, and this definitly help me plane out to gain some speed. Easy installation and the price made this product a good investment.

I purchased this Doel-fin for my 20' pontoon boat. It was heavy in the rear end. I have a 50hp yamaha 2-stroke motor on it. The fin gave me the lift that the boat needed. This is the second Doel-fin that I have purchased. I also have one on my bass boat. They work great and they are very easy to install.

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?
