Fingers crossed, I’m sure if I built another it would go a lot smoother being my first one. Unfortunately these builds don’t come with builds instructions so lots of trial and errors/ cutting and welding to make it work. Which eats time
Proper sand filtration/ shell and tube heat exchanger. Stainless wear ring and impeller. Good to go. All parts relatively inexpensive comparable to a Hamilton or Scott pump on the a big/ small block
Hate to tell ya but you ain’t getting 215 at the pump, more like 114hp with the pump curve. Just like any boat run it at 7800rpm it drinks the fuel back. My rotax seems to be most efficient at 4800rpm on step. But let’s face it who want to Cruze at that.
Roughly 10 hrs on it now after tunning and adjustments. Pretty fun no question. Just need some final welding brackets and such, then Paint/wrap/ flooring
Between the stringers gap you suggesting? Was more to get the “ting” out of the aluminium on the water. The noise of the Rotax is up there but nowhere near a sportjet or stroker
