Adding sting-ray hydrofoil to motor

[dell30rb]

I recently put one of these on my boat, a 1992 proline 230 WA with engine bracket. The original motor was a 2 stroke yamaha 225. Repowered to a 200 suzuki 4 stroke a few years ago. The extra weight of the 4 stroke on that bracket really screwed up the trim and made the boat ass-heavy. I added one of these recently and it really helped out. Creates alot of lift back there and got the trim right. Best $50 bucks ever spent on the boat.

If you get one, get the ones that bolt to the motor (where you drill holes). The clamp on ones are more expensive and suck. The clamping thing is really crappy.

yes they work but keep and eye on it because they are know for cracking cav. plates. i belive one of the engine manufactures had a bullatin out that the dol-fins could not or should not be used on there engines.

Do you have trim tabs on it?

Drilling and installing dolefins on a Merc voids some of the warranty. Be careful

Have the Doelfins on my proline and love them
