When I bought my boat I was told it had an 88HP 1988 2 stroke motor. I was reading through the manual, and found the description of the tags and "introduces" code.<br /><br />I don't have a riveted tag, but there is a sticker with the following on the clamp under the motor.<br /><br />VJ88MSLCER<br />R8151393<br /><br />There is also a silver plug on the top of the head that has the second number from the tag stamped on it. R8151393<br /><br />If I follow the code, I have a 1994 engine? <br /><br />I have decarbed the motor, replaced the wires and plugs. It still runs a little rough. The 1988 motor calls for .40 gap on the plugs and 1989+ calls for a .30 gap<br /><br />Thanks in advance!<br /><br />Mike
