Marine Sport SE 200 High Performance Hydrofoil for 8-40HP Motors, Gray -

I recently renovated a 1973 Starcraft that has a 20 hp mercury motor. First trial after installing and as I increased the throttle the nose would go up so I couldn't see and it was tough to get on plane. I'd open the throttle up all the way and the boat would get up to about 25-26 mph, but very quickly the boat would start porpoising. I was really nervous installing this. There's a few quick videos that show how to install the foil. The template was really helpful. Even with that my holes were slightly off, but the foil was forgiving and fit like a glove. Took less than 20 minutes to install. Now boat gets up on plane very easily, handles much smoother, I lost 1 or 2 mph on the top end, but no more porpoising. It did the job it was supposed to.

Parece que solucionó nuestro problema de cavitación. Sin embargo, poco después de instalarlo y ponerlo en marcha, nos robaron el bote auxiliar, así que no tengo idea de cómo resiste el paso del tiempo. Ahora tenemos un motor eléctrico que no gira lo suficientemente rápido como para necesitar uno de estos. Pero, al menos, el motor es silencioso y la fauna no nos oye llegar.

I had a whale tale version on my 20HP that broke. I find this one looks much nicer and planes the boat just as fast or faster than the other version. The fins on the back help keep the engine straight so the torque doesn't pull the tiller nearly as hard as the previous tail. I will put this tail on my outboards going forward.

La compre para un yamaha 8 cv porque me levantaba mucho el barco. Hay que taladrar para ponerlo pero una vez puesto cumple su función.

Item arrived relatively quickly and at a reasonable price. Item works as described, easy to install and has an immediate effect on the boats cavitation.
