FOR A RELIABLE LOWER UNIT, CHOOSE LIQUI MOLY GEAR OIL
Whether on an outboard or sterndrive, the lower unit needs clean, fresh gearcase oil for continued reliability and to extend its overall service life. While changing gearcase oil is a simple DIY task typically done once a year or every 100 hours, a premium product should be used. Fully synthetic LIQUI-MOLY Marine High Performance Gear Oil SAE 85W-90 is the ideal choice.
