Hello Forum Folk,<br />I just purchased this motor with 20 hours on it.<br />Has anyone ever heard of the "Commercial" designation to what basically looks like a standard 15 HP Johnson. The Model number is HJ14RSF. It is not listed in the iboat guide. Anyone know what makes it "commercial"? It does have a 12 volt outlet on it. That's the only difference about it I can see.<br />thanxs, Harry
