I have a 2000 Bayliner Capri, 17.5 feet, 135 Merc I/O. Runs great, especially since I installed a water seperating filter, but at slow speeds, +/- 25 knots, I have to constantly correct the steering. The steering wheel gear doesn't have too much slop, I don't think.(how much is acceptable?) The tab is offest a little, about 15 degrees on the stern drive. Any suggestions? Thanks,Larry
