Checking Lubricant Level
1. Place the outboard in a vertical operating position. Allow up to 30 minutes
for the lubricant level to stabilize in the gear housing.
2. Remove the lubricant level plug. Verify the sealing washer is not adhered
to the bearing carrier. The lubricant should be level with the hole or slowly
leak from the hole.
IMPORTANT: Replace the sealing washers if damaged.
3. If lubricant is not visible at the lubricant level hole, remove the fill/drain
plug and add lubricant until it appears at the lubricant level hole.
4. Stop adding lubricant.
5. Remove the lubricant tube and install the fill/drain plug and sealing
washer.
