I have recently bought an old Yamaha air cooled outboard (as an aux on a boat) and I can't identify it. It is air cooled pull start with a built in tank. The tank is dark green and the rest of the body is cream. The serial number has been partly obliterated - it is 0528?.<br /><br />Anyone any idea what model/HP it is?<br /><br />BTW It starts and runs well - pulls the boat (17ft, 750Kg cruiser) along at about 6.5mph.<br />
