I asked about gear oil and wasn't sure But got answer. In fact it was about Mercury gear oil and not being Johnson gear oil. For that answer I thank you.
NOW. Looking at gear oils at boat store & automotive stores my manual says Johnson gear oil or equivalent with GL5 rating. NOW. Valvoline gear oil 80/90 is GL5 rated and for outboards as well. Yeah I know this sounds dumb but have to ask since I ain't no mechanic, is the only difference in these gear oils "the price"?.
AGAIN this is being used for a 1962 40HP Johnson outboard
