New to boating: I have a 1990 90hp evinrude. Drained the lower unit and didnt get out much lube- 10 oz lube was in good condition. My question is what type lube should I use? synthetic 90w?

Re: Estoman

80-90 lower unit gear lube is the requirement, if the synthetic meets the criteria, no problem. please put part of you question in your title.
