I'm after an aux motor for my 15foot fiberglass boat. The boat is a 79 model and probably weighs between 300-350kg I think. I'd be buying a secondhand two stroke 10-20 years old as I can't afford a new one.<br /><br />This boat is primarily used in "non tidal" seas and waves to 0.5 to 1.5 meters out in the sea maximum. Don't go more than 10km's out.<br /><br />I have heard that it is best to buy a motor with the lowest HP possible as they are lighter and still do the job of getting you back to shore. <br /><br />Also, I've already got an adjustable bracket bolted to the back of my transom. Main engine is a 55HP.<br /><br />Suggestions please.
