This is my 19' Legend race boat. It was built for white water marathon river racing. I have had this for over 20 years, and I just use it as my hotrod. This year, I built an all aluminum 540 with mechanical fuel injection. I haven't put it in the water yet, but the engine has been dyno tested, and also run on the trailer with a wet kit to make sure there aren't any leaks. The boat is a welded aluminum vee bottom with a Dominator jet pump. It should show about 6000 with an A3 impellor.
