I ran my new rig this weekend. <br /><br />1544 Weldcraft with 25 HP merc tiller Steer.<br /><br />I runs great but it pulls to the right (hard). I have to hold on to the side of the boat with my other hand. It's not bad at slow speeds.<br /><br />I turned the trim tab as far as it would go. It might have helped a little.<br /><br />What else can you do? What causes this?
