I have a 1992 17 foot inboard/outboard boat. The sterndrive is a Mercruiser. I believe the engine is a 3.0 liter, 120 hp.<br /> I recently installed a hydrofoil stabilizer; attached to the cavitation plate.<br /> <br /><br />The boat steering is pretty stable at about 28 to 30 mph. When I increase speed to full throttle and get the speed up to about 34 to 36 mph it pulls hard to the left. I have checked the skag and it appears to be pretty straight, although is very slightly twisted at the bottom. I also adjusted the trim tab that is located just above the propeller as far as I could but it still pulls pretty hard to the left. <br /><br /> Is the hydrofoil stabilizer the problem? If it is the stabilizer is there anything I can do to correct it? Could running it like this cause any damage to the unit? I do like the improved ability to plane out quicker that the stabilizer adds.
