"I have a pontoon boat with a 50 horse merc. which I would like to replace with a used honda 4 stroke. Is this an easy replacement. I would be replacing with power trim/tilt and electric start with steering done by the original steering wheel on the pontoon boat. What is my best direction in looking for a second hand motor. Do I need to buy it with power trim/tilt, electric start and all steering cables included or can I buy whatever I can find and ad the trim/tilt, electric start, and/or steering new? No experience at this so not sure what my best approach is. Thanks for any help."
