I have a yamaha 25hp outboard that constantly wants to turn to stbd while at higher throttle settings. I have tried moving the trim tab behind the prop to the right and it helped initially, but it is now maxed out and still has a significant pull, to the point that I almost need two hands to turn to the left. The prop was pretty dinged up when I bought it, but doesn't look like there is any new damage. The issue seems to getting worse. I don't know if the skeg got bent a little launching a little too dry, but it doesn't look damaged any more than when I got the boat. Anyone have ideas on what could be causing it?
