I hear that. What I think....uh, ya....you need is a Whipple setup...... My Ultra with the same was bullet proof. Ever consider it?
Nope, completly happy as is Insurance no problemo and reliable. If I keep it long enough my cuz can make about 600hp during the rebuild and still keep the reliability, and very stealth.
John, yep those speeds go down with summer heat dont they. Who cares, your boat runs exceptionally well and everybodies numbers go down with the heat just as yours did, unless you have something wrong with the motor?? I hope not!! Bobby
