Ok, fired the engine up this evening....well, sounds healthy. Going to spark limit it to 4800rpm to possibly 5200rpm, untill I can figure out the drive situation. My biggest fear is the thing pulling up from the hull. I have it strapped down, just in case something goes horribly wrong. Man alive, this thing should be in a car

(The gentleman has a really nice 88 7 series BMW I did for him, and keep telling him he should let me put it in that.....lol) Possibly a different drive unit altogether? What does it take to be able to reliably spin an out drive to 6500rpm? What fails? Bearings, or gears? Jet drive possibly? Or am I just off my rocker, and keep it dialed way down? (hm...way, way down)
