I have the Stiletto mentioned above on my 1989 with 1998 Yamaha 90 2 stroke (great engine btw). I carry a lot of gear and it's still mounted in the blind holes/all the way down but I'm only getting 4400 RPM and 31kts WOT with my average load.
I plan to re mount the engine but don't think it will make that much of a difference. I rarely need/want/have the opportunity to run faster than that but wonder if there's a governor/throttle adjustment I could make or if I just bought the wrong prop. I only gained a couple kts and rpms from my old aluminum.
Ps: how much did you pay for the engine. If mine dies tomorrow I'd be torn between a used 90 / 2 stroke vs 70 / 4 stroke.
