Quicksilver Gear Lube Pump Adapter.
This adapter converts from 3/8" thread on the lube pump to 8mm on the gear housing for Japanese based outboards
It is always strongly recommended that the Gear Oil be checked and replaced after every 50 hours of salt water use and before storage at the end of each season to prevent damage to the gearbox through water ingress through the propeller seal, should it have failed during the season.
