Question

I cannot find the year of this boat engine and drive, Mercruiser serial # 6877068?

Answer 1

it is a GM 153 I/L4 1983-1986.

mercury does not go by year models. strictly serial. so there really isn't any way to tell what the exact year is. if your boat is between 83 and 86 it is probobly the original motor. so it would be the same as the boat. the last 2 #s of the boat model # would be the year

Answer 2

Looks like an 85-86 GM 4cyl 120

Answer 3

If you obtained that number off the little stern ID plate of your boat, and if it is the original engine and drive, it is a 1968 year model. On the boat ID numbers, the year is indicated by the last two numbers.
