I have a 3-Cyl 1988 90hp Merc ELPTO motor with a blown foot. Serial on my engine is B347250. Took foot off and looked at the casting number on inside of lower unit on top of the cavitation plate. The number is 1667-9010-C with a smaller numeral 5 after the "C". I have found someone with a 1987 80hp 3-Cyl, but the part number on his lower unit housing is slightly different.... 1667-9010-C1, not C5. Serial on his engine is B218952. Does anyone know for sure if these are compatible?
I measured my drive shaft and its 20". He states his is 22.5". I thought they were either 20" or 25"...... not in-between. But, the amatuer I am, I could be measuring improperly. I measured from the base of the drive shaft, where it enters the water pump housing cover, up to the splines.
Any advice would be greatly appreciated.
