Re: Need ideas to stop porpoising?
Gilly's right. Raise the motor to pick up rpms. You could get an extra 200-400 rpms by doing that. Of course, you might not, too. But you will gain something.
35 mph WOT in a Sceptre with a hardtop running a 200 Opti is good numbers. 25-26 mph should be your normal cruising speed with that motor. I recently sold a '74 Tsunami with an '89 225 Looper Johnson, no hardtop. I ran WOT at 5400 rpms, and 37-38 mph with the bimini down. Bimini up I could only get 34 mph.
