Anyone with info on fuel consumption / cruising range for a 1989 34'
Searay Sundancer with twin 454's, closed cooling system? Am
considering purchasing one that's in good condition but am a little
bit concerned with cruising range with 170 gallon tank.
TIA, Tony

If you go easy on the RPMs and find the spot where it's just on a
plane and trimmed properly (don't know if what you're looking at has
trim tabs) you can probably get close to 1 mile per gallon. That's
going to be somewhere between 2500 and 2800 rpm.

You dare not open the secondaries since that's an invitation to
bankruptcy.
