Hello looking for some help my 44 aft is not planing and I have decided to have props computer balanced and polished at frank and jimmys in ft Lauderdale does any one know the size and proper pitch for this boat and also my rpms and any vital information.
on sea trial she was trimmed fully down and she would not get over and plane temp was good and rpms were like 1800 to 2000 which I think is ok for the cats bottom was clean but I am redoing before I
put her back in the water I am not looking for a speed demon but I don't want to be a trawler !!!!! Any info on fuel Gph and cruising and top speed as well as optimum rpms would be great .. Thank you
ted

Decided today we going to pitch prop down 2 degrees according to cat I should be 24 to 2800 w.o.t. Does any of the 42 to 44 aft guys with agree?


Thank you..

2300-2400 cruise, 2800 WOT with a full load (fuel, water, gear, etc). Check your engines for neutral WOT, probably right around 3100. I am assuming these are TA's?

Thank you, I am surprised the rpm range is that hi for a 23000 lb boat,
i will pass that along to the prop shop,, is Ta mean its a turbo? If so yes the engines are turbo charged..

Thamk you..

T=turbo A=aftercooled. What horsepower engines do you have?
