Yes, use 90 weight outboard gearcase oil. Hypoid oil mean oil for hypoid cut gears. All modern outboards use hypoid cut gears so modern outboard gearcase oil is hypoid oil. Generally speaking, these oils are smelly.<br />Hope that explains it!
Thanks, smelly they are. I have already put the standard lower unit oil in. I wanted to make sure it was ok, if not I would have changed it. Again, Thanks.
