I have just bought a boat with an old Johnson 15HP Sea Horse motor and wondered if anyone could tell me the year so that I can hopefully get a service manual. Any advice on where to get a manual would be appreciated.<br /><br />The engine model number is J15BALCNC (the label is scratched but I'm sure that's correct) and the serial number is B013288.<br /><br />Thanks in advance for any help.
