Hi everyone,

Looking for the part number of the gearbox drain/fill plug gasket for a JW-10 outboard. I see some people mentioned that its a crush washer, other mention an O-ring. My SAE 90w oil has already been ordered, just want to be prepared with the right crush washer/gaskets to complete the job.

Ordered these based on my research:

Not sure if they will work though..

Motor is running great, my father purchased this motor for me ~15 years ago when I built a plywood Jon boat. Only issue I see with it is it leaks fuel from the high speed adjustment, ordered a carb kit with new packing washers, assuming this will fix the issue

These washers were the same for about 50 years.-----They will work.
