Review on 🛥️ Yamaha Yamalube OEM Gear Lube Kit: Lower Unit Oil, Pump & Gaskets for 2 Stroke & 4 Stroke Outboards (F15-F250 F-Series) by Doug Mancilla

This kit made servicing my bottom unit a lot easier. The included nut screws right into the bottom drain hole, allowing you to fill it up while pumping. Remember the pump straw to make sure you tighten it firmly. If it falls into the oil you have to do like me and just turn the bottle upside down (it took me a minute to think about it). The kit includes new washers for a good seal.
