I need help on the year of my mercury 500, 50 hp i have no serial # on it. That i can find. on the side of the block the # is 27935 on the carb(i think) the model number is 4D-4. please help!
Is it the kind with 4 coils or 1 big coil and a distributor? If it has a distributor the S/N is stamped in the block above the distributor. It'll be a 7-digit number.<br />Eric
