People always think I'm crazy....for top speed, I've never found anything faster than my 30" Mercury Cleaver. If you have a lot of lake, strap a 32" Cleaver on. I had a 32" Mercury Lab Cleaver that was insanely fast on virtually every boat I had the ballz to hang on to. We had 4 boats running 110 MP+ for about 4 miles across Lake Koshkonong once in Wisconsin. Me and a friend in my SuperSport/280 and Bill Gohr in his XR-2002/mod 260 ran side by side that whole way well over 110. I could touch 118 by myself with that prop and it would run about 114 with two in the boat. They handle like you have power steering too.
We race a 1000' speed run and the 30" cleaver was the fastest prop every year we've run there. Last year I had a warmed up Evinrude 225 on a SuperSport and Nick Winski had a 260 on an XR-2002. Everybody else was running 24" and 26" yamahas because it wasn't that long, but the 30" Mercury still ran the fastest top speed. Nick ran 97.2 and I ran about 93 MPH from an idle. Try it...you'll like it. You'll run HUGE numbers in an XR-2001 though. I don't even know if I'd want to try that. I'm getting too old.
