I got an 18ft Lowe Pontoon boat from a friend that let it sit and rot. I have stripped everything down and am currently waiting on a guy to finish welding up a center toon with a built-in transom that he says will be rated for up to 300HP. I plan to rebuild it as a center console fishing machine that would also be able to pull tubes when desired. My question: On a smaller/shorter tri-toon what would be a reasonable size motor to install? I am thinking 200-225HP but don't know how much is too much.
