I'll be changing the lower unit oil fairly soon as it seems like a simple job. I'm looking for opinions on the type of gear oil; I'm assuming 80w90 correct? Any preferences such as Royal Purple, Quicksilver, Pennzoil, etc that you have used?
Also, where would you buy the washers for the drain and oil level screws? Any marine supplier?
