My current stern driver is shot, the oil had tons of metal in it and was almost in a paste form. I found a guy who will sell me a whole rebuild drive(upper & lower) for cheap. cheaper then i can order parts for.
he as 2 drives available. 21:16 & 21:17.
looking at my drive I don't see it marked like the manual says it should be. I looked through the service manual and I don't see where it says which is which.
my guess is the 21:17 goes to the Ford 5.0L & the 21:16 goes to the GM 5.7L. the GM is more powerful so it can have taller gearing.
can anyone confirm this?
this is all I could find in the stern drive section but the math doesn't work out 21/17 = 1.23 & 21/16 = 1.3125
its a 1986 with a GM 5.7L
