My 17.5 ft. Deep V Smokercraft boat with a 2015 115 hp Mercury 4 stroke pulls hard to starboard, especially when cruising 35+ mph. I have tried adjusting the trim tab in both directions multiple times and adjusted engine trim. I found the best combination to reduce torque pull but still have to turn wheel to Port and hold tight. I have looked online at NFB Steering helms and hydraulic steering systems. I would appreciate feedback from any of you who have experience with these steering systems. I want to minimize cost but also want the torque pull issue corrected for safety and steering fatigue reasons. Thank you for your time and help!
