I have a 12ft Jon Boat new to me with a 20hp Suzuki outboard and it is really too heavy as I sit on back bench with seat nearly all the way to right side of bench so that I can actually steer since tiller needs the center of back bench area. I am the only one aboard and it puts too much weight on back right corner of boat, only a few inches of boat above water there. It is terrifying when I steer at high speeds because just the slightest movement of tiller left or right overpowers the boat's balance and things go haywire, so I have to slow down so much to make slight turns. I hope you will advise me on how to rectify this problem for safety reasons. My plan is to get a tiller extension and try to sit in the middle of the bench in front of the back bench, but I don't know how I will be able to truly be centered on the bench to balance weight since the tiller extension may still be forcing me to move my seat to the right side of boat. That leaves me imagining making my own bizarre Tiller extension that would basically be PVC extending forward to make a large to a "T" that extends further to a SQUARE PVC SHAPE THAT WRAPS AROUND MY BODY in order to make it possible to sit perfectly centered on the bench nearer front of boat, which is actually in the center of the hull. This is the only way I can imagine being able to get centered in boat for balance and able to steer, but I am not sure if the DIY PVC Square shape of a tiller extension will be safe to really try. Please give me your opinions.
