My last 2 boats 35 and current 38 both had to use full tabs to get on plane. Both high X Bravo boats needed the extra help to get on plane. Obviously the OP is going to have to get some running time on this boat, find a good groove and make sure all is up to spec..

It takes full tab to get my 27 Fountain on plane. It would probably get on plane without any tab but it would take a country mile. I have no interest in trying that. Tabs down and it pops right up on plane.

en I got my 34 Scarab with stock drives it would do that. That was using 3 blade props. I had to ease it up on plane.
Then I went to 4 blade Bravo props and I could pull stumps getting on plane. Then I went to -2 inch IMCO shorties and it would not blow out but would slip.
I never had to use tabs with any of the setups. BUT with the -2 shorties I would just ease into the throttle until it started to slip and then I would just hold it at 5000 RPM until a point where you could feel that you were going fast enough - I then would just back off the throttle and then get right back into it. Doing this made it hook up solid. Hang on.
With my 26 Daytona my prop shafts are 2 inches above the lowest point on the hull so if you tried to get on plane you would quit when it acts like it blew out but in reality I just hold it at 5000 RPM and it gets to that same point where I pull and reapply the throttle. Again HANG ON.
