Will my outboard come with lower unit oil already pre-filled?
Yes. The lower unit gear oil has already been added at the factory, however, you should check to ensure it is completely full before starting your outboard for the first time. To replace/add lower unit oil we recommend any SAE 80 or 90 weight oil.
For information on how to change and check the oil in your lower unit, please read our step-by-step lower unit oil change instructions.
