Guys, found an old thread on this and could not find an answer. So, here's what I got: My trim fin(or whatever it is called) on the motor(40HP 4 stroke) was straight when I got the boat. When I powered up to get on plane, the boat has always pulled HARD to the right. As I got on plane, I kept trimming the motor up and the steering went neutral,(this is what my dealer said to do). I was told this was not correct. So, I changed the angle on the fin recently so that (from the back of the boat) the back end of the fin was pointing right to hopefully help the initial problem with the steering until I could get up on plane and start trimming. It got worse after this adjustment, and even with trimming up now, it pulls slightly to the right. So, what would you do? Put the dang thing back to 'straight' and live with the hard pull to the right until I can get it trimmed up, or try something else. I guess I could try to move the 'fin' so that the back of the fin points to the left and see what happens. All I know is that if I let go of the steering wheel now when getting on plane, the boat will do an immediate 360 turn until I can find the proper trim level. I can deal with this, but I have to make sure if ANYONE else is driving the boat, they must hang onto the steering wheel until they can get the motor trimmed.
