Re: Need Info on Mariner 15HP
eppinett <br /><br />I would check that serial number again, as I cannot find it either. Maybe the "S" is a "5". Nevertheless, you need to order a rebuild kit for the carb and remove it from the motor to clean it. Sometimes, if it's not too bad, you can dump some "Seafoam" in the gas tank and clear it up. do a search at the top of this page for Seafoam. As for the starter, I would not want to give advice on that because it can be dangerous to service if not experienced. I would take it to a small engine repair shop and let them deal with it. Also, a Manual for you're motor would be a great help.
