Recently bought a 34 PC with 496 Seacore/Axius. I'm having a tough time getting her to efficient cruise. at 3500 she's at about 23 mph and 44 gph, 3/5 tank of fuel, 1/2 tank water, 2 adults.
I believe the drive ratio is 2.0:1 and standard 3x3 B3 prop set. This seems way too slow and way too much gas. I put about .5 up trim on engine (as shown by vesselview) or maybe 1/8 up on the analog trim gauge. Trim tabs were in the middle of deployment. Looking for anyone who has nailed the best cruise with this set-up between trim and tabs. Anymore up trim and the bow comes up, and rpms race up. down trim tabs seem to help speed up to a point.
Thanks to anyone who answers.
