Hey Folks,
I have a Mariner 8M, Serial Number 677S 035288 (Yes, that is an "S", not a "5") From what I can figure out, the year built is 1980.
Had to pull the head for a water passage problem. Tried to put it back together and started snapping off head bolts. I've got a manual for 1990 or newer mariner that says the head torque is 60 FT LBS. Based on the breaking of the bolts and the size, this can't be right.
I am going to tap the head holes to the next size (1/4") and need the correct factory torque specs for the head bolts.
Thank You in advance,
Eric
