I know this has been beat to death, but trying to taylor to my 08 Cougar. With full fuel, full wells, 2 anglers and gear, 3 batteries and hydraulic plate. With boat trimmed out for Max top end, the pro xs 250 is at 6100-6200 rpm and gps speed is 73.4. my question is should I be running a 26p versus the 25 Im running to bring the rpm back down?Butch P

Sounds like u have alot of slippage. May b running plate a little to high or a little too much trim. Prop may have lost some bite too if it has alot of hours on it. If you went to a 26 Fury you should lose about 200 rpm. I have a Puma FTD and with the 25 Fury with 2 guys, full fuel, 2 poles, 4 batteries, livewells full etc., in the summer heat, I turn about 5900 at 76ish

It sounds to us like your too high on the plate. We feel you are experiencing a lot of steering wheel torque when your trimmed up, and that indicates your too high.

Thanks for the input. I will try running the plate a little lower until there is little to no torque in wheel and see how this goes.Butch P

Also trim up in taps, not all at once. There may then be a sweet spot you find after you lower it. Presently the numbers you share indicate its about 1/2″ to 3/4″ too high.

Good point BCB, I do tend to get a little impatient. Butch P
