Welcome! Need support, you got it. Or share you ideas and experiences.
I have a 1996 scout 17 foot open fisherman, with a 115 yamaha outboard 4 stroke engine. It pulls to the right pretty hard. If you let go of the wheel it immediately turns to the right.
Look for a small adjustable fin pointing downwards from the anti-cavitation plate, behind the prop. Turning it off to the left (while standing behind the motor) will produce a force (when moving through the water) that pushes the tailend of the motor to the left, and tries to turn the boat left. You may be able to correct the steering at full throttle only to find that the boat may still try to turn right at slower settings. If you get it to go straight at half throttle, it may still want to turn right at full throttle.
well, Im prettymuch just guessing here, But there are a few things to check. Is the motor mounted square to the frame? Is the Skeg bent?. If you have tabs, check them as well,
As far as an adjustment on the lower end. I dont think it would be a lower end adjustment. If anything I would look at the stearing control for adjustments and or broken missing parts. I have seen springs used as well as strut looking things incorperated into remote stearing devices. that would be a good thing to check.
