Need help, I am new to BBC. I have an 07 bass boat with hydraulic steering, 10" manual jack plate and 250 Merc. I think the problem could be in the skeg. I've had this boat about 2 months. Turning left seemed a little stiff when running WOT. Noticed skeg bent to the right looking at it from the back of the motor. My buddy said, straighten it up and it will work good. It got worse, have to let of throttle to turn left when wide open throttle, about 70mph. Running a 25p fury. Also, can a trim tab be added to a merc 250, noticed it did not have one and my old 150 had one. Need help from someone that knows more.
