I'm gearing up for summer 2010 and I have a 16' Klamath. I want to power with a 4-Stroke because I plan to be in the Kenai system 80% of the time. My boat is rated for 55 hp. Questions: Which model would you recommend? I do plan to be in the salt water and would like to ability to go from point A to point B quickly, but at the same time would like to troll/back-troll as well. How much moter do I need?
