Hey there Carver owners, this is our first big block 454 engined Carver, and I was wondering if anyone had any idea of the best cruising speed for the 36 aft cabin? Right now we’re cruising at about 2000 RPM and getting about 8-9 knots depending on the tides, burning about 12 gph, Has anyone found a faster cruising speed, such as on plane at 3-3200 RPM any more economical than what we’re doing now? I know that our 42 aft cabin with the 375hp Cats was got about 9knots at 1800RPM burning about 6gph, but I know that you can’t compared gas to diesel. Our 36 Uniflite aft cabin with small blocks got about 6 gph at 9 knots, but this Carver 36 aft cabin with the big blocks burns a whole lot more than the Uniflite with the small blocks, but then the Carver is a lot more boat than the Uniflite was.
I know that any big block powered boat is not going to get good fuel mileage, but anything better than burning $125 of fuel and hour would be nice. By the way, I’m going by the Navman floscans that are on the boat.
Thanks for any suggestions
