I would've had a GPS to use but my stoner friend slept all day and I couldn't get a hold of him. Ok, with two people, 3/4 tank and completely flat water...it pegged the useless speedometer past the 55 limit and onto the peg. I had the drive trimmed up a bit and we were moving. I don't have my Donzi manual in front of me so I don't know what the factory max rpm is but I was running full tilt at 4600 RPM with a Vengeance 19P. Is this RPM too low or just about right?

Rootsy, maybe you can tell me stock rpm limit?

4200 - 4600 rpm WOT range on that motor...

figure 10% slip for that prop, adding 1 inch for cup, 4600 rpm and a 1.47:1 drive ratio and you were doing in the neighborhood of oh... 53 mph.. right about where i used to run WOT in stock form...

JR - one pissed off little rodent under my hatch :D
