I own a 2000 18 foot Smokercraft 182 Pro Mag, with a 2000 135 Mercury motor, 2 stroke. The problem I am having, is that at higher speeds of 10 mph or faster, I have to hold on to the steering wheel with everything I got, or else it will do a 360 to the right. This is not safe, and I am worried about it. We tried to adjust the little skag, in several directions, but it has little to no effect on the steering. I need some help with this, anythinbg would be greatly appreciated. Thank you for this great site as well.
