The Oil Block Off Kit allows you to remove your 1976 to 2005 Mercury V6 2-stroke oil injection gear, which runs off the crank, to reduce engine drag and allow you to premix your gas with two-stroke oil directly in your fuel tank.
 
This kit includes one (1) block-off plug, one (1) sealing o-ring, and two (2) mounting screws. It replaces the Mercury Marine / Mariner OEM part numbers: 818304-A1, 8M0095447, 43453, 43453T, and 32509.
 
Includes one (1) complete Oil Block Off Kit as pictured.
 
Install by removing the existing oil pump and drive shaft, aligning the insert (it goes in just one way), installing the O-ring with a light band of silicon around the O-ring area, and lightly torq the included mercury bolts to secure in place.
