How much gear case lube?

[southwestboater]

I've been gifted a nearly mint 1989 DT15C and I've yet to find out how many milliliters of gear case lube it needs because it needs to be changed. Thanks in advance.

Not sure either, but in any case, you fill it by squeezing/pumping in oil via the lower drain hole until it comes up out of the top hole. Then it is full.

DF15 gear case refill quantity

I believe it holds around 14 ounces. Buy a Quart and fill it from the bottom until it appears at the upper hole then secure the upper plug. Secure the bottom plug quickly when you remove the bottle of lube.
Hope this helps!

Thanks for the quick replies! I've never owned an older Suzuki until yesterday and my Google-fu didn't get results on the matter so again thanks.
