I am new to boating and have a couple of questions. First i need to repower my 1987 16 ft aluminum sea craft. i currently am using a 20 hp suzuki and i don't move as well as i would like to. I am considering a 1999 40 hp mercury 2 stroke and would like some opinions on this engine. I would be buying this from iboats and want to know if anyone else using this forum has had experiences (good or bad) in purchases from iboats.
