I had hoped that with the 1988 115 HP Mercury on the V-153 to have reached 55 to 57 MPH with the right prop. Tom from the Twin Cities, reached over 60 MPH with a 115 HP Mercury on this CVX-16. Motor elevated, 24" Laser II, hull blueprinted. He is not in the Glastron group, just a chance meeting after a river run with Jason, Gregg, and myself. He was always experimenting and a stickler for details.
