I got this for my 750 King Quad. It was a very good price compared to dealerships out there. Hopefully I will find this again in a few years at this price. Doubtful.

I noticed my marina was using the same gear oil for every outboard lower unit. I decided to go with Suzuki specific gear oil for my winterizing process.
