dyno I could only run 68-69 gps (at best) with the tired 502 mpi's sounds like yours works real well. you must love the long rollers out on lake michigan ..nice air time

Nice numbers, what year is your boat? My 88 is so loaded up with heavy cruising and fishing gear, I have dropped down to about 50 MPH with twin 350 HP scorpions. Guess it is not a go fast anymore.

Best GPS on it WAS 72 MPH, fresh labbed props, high X, stripped light, wind and current going in the right direction.

1997 only things missing are ac and binim top works real good
I have to play a few games to run 82 props,fuel psi and timming but last I checked everyone plays around to get mph.

belive it or not I take my son fishing off the back!!hope my freinds don't see this post I'll never live that one down..
they call the boat by two names:

super sonic and super sleeper the later seem to fit well

CBR

Yup, the engine hatch makes a great fishing platform. I have caught lots of fish off it.
