Sure the serial # is posted correctly?

There should be no "I" in the last series of numbers. If the last series of numbers are correct, your 28HP motor is a 1979 model year.

HI
try searching for the Yamaha 28hp diagram. Much more commonly known and exactly the same engine. Mariner were Yamaha in those days. Good luck.
