Lower unit lube

[Strokerdean]

Helping a friend, where is the fill/drain screw on the lower unit? There is one at the top of the lower unit for level but can't find another. Do you fill to the top or do you leave a little space for oil expansion?
Thanks

Pull the screen off the water pick up. the drain plug is under it.

Thanks, I'll go out and take a look.

You need an allen wrench.

Thanks CStewart and Mike, pulled the water screen and checked the lower unit. This is diff than the 300xs I run but I guess I will learn more about the Yami as time goes on.
