I bought a 19' Key West fiberglass boat that has a Suzuki 115 2 stroke on it. I got a great deal on it so I couldn't pass it up. It seems to run great in the driveway but I have not put it in the water yet. I also have a 60 HP Yamaha 4 stroke that I have sitting around not being used. I believe that it is geared for heavier loads, but I need to confirm that. I have always been an inboard/bigger boat guy so I am not too familiar with the smaller setups. I know that it will be slow, but would the Yamaha be sufficient enough to use? It is a 7'6" beam, so its fairly narrow. Any suggestions/comments? Thanks!
