Hydrofoils for Outboards

I have a 10.5' TwinVee with a 100lbs short shaft outboard sitting on the stern. It gets on plane OK but the bow rises and the stern sits down more than I would like. I was thinking about putting a hydrofoil on the shaft just above the prop to make the transition to plane smoother. Does anyone have experience with these? I have plenty of power for speed, so the additional drag is a non-issue. I just don't want to add stuff to the boat that doesn't do much. Thanks - Matt

I haven't seen the need myself, but what you are wanting one for is the exact reason I believe they are made, to lift the stern, sort of like trim tabs, and also they make you plane faster, that is the bow comes back down sooner, or so I have been told.

Matt, it's the best $40 you will ever spend. Seriously. It changes your dink to a totally other boat. I get them the day I get a new OB.

They work. With just me in the 10 ft dingy, and a 9.8 hp Tohatsu, I can plane in just over one boat length.

Inexpensive performance improvement.
