I just found out that my overheating and restarting problem was caused by a fried (nearly dry) lower gearing unit. I'm now looking at a used lower unit from a 1991 90HP to put on my 1990 120 HP engine. Both units appear to be dual exhaust and compatable. As long as I have the shaft and coupling
from my engine, does it matter whether the replacement is coming from a long or short shaft engine ?
From a reply Frank Acampora previously posted, it appears that my unit might be a 20" short. However, the shaft actually measures 24" not including coupling. - So I'm not positive what I really have.
