Carver Owners Forum

Hello Everyone,

Does anyone own a 92 carver 33’ aft cabin with twin Tamd41b diesels and If so what is the speed at WOT and cruise?

I think I may have the wrong pitch props, it wont get up on plane .
3800rpm WOT @ 15mph and 3100rpm cruise @ 11mph
Burning approximately 1 gallon per mile total for both engines @ 3100rpm
All tanks empty except 220 gallons of fuel. All canvas removed to lessen wind resistance
Typical Volvo smoke on start up (very light fuel smoke) and smokes light black when ran WOT
Engines have 450 hours each and run perfect


Bottom soda blasted and fresh barrier coat / paint. The bottom is clean and so is the running gear
Trim tab fully functional and using them makes no difference in speed
New A17 shafts, props reconditioned and pitched to 18”x16”, shaft logs rebuilt, new cutlass bearings
Racors and engine fuel filters replaced. Engines totally serviced and all breather/ air filters changed
New turbos and they both spool up , new exhaust from engine to stern, new SS elbows
Valves adjusted to .016”
Tested lift pump pressures and cleaned / tested and cleaned injector pump pressure regulator valves
R&R cleaned and tested fuel injectors
Fuel is new and treated filled to the top both tanks to prevent moisture

Any suggestions I’m running out of things to check or maybe this is just a slug slow boat.
The last owner records show 17.5 knots WOT (about 19mph from a third party sea trial) before the bottom came up and hit this boat in 2017. Apparently he had it fixed. I bought the boat in 2019.

Thanks for any feedback

Those props do seem pretty small. What kind of reduction gears do you have?

Does the boat pop up on plane pretty easily?

Welcome to the forum......do you know what the WOT rpm spec is for those engines ?

My '92 350 AC gas Crusader 454 velvet drive 2.57:1 has 22x22 props, and gets approx 22mph at 3200 rpm. Sort of hard to relate speed OTG vs rpm on the Hudson with tidal currents, but that is ballpark.
