Re: 1958 5.5 hrs johnson
The old O rings that do the sealing, are probably hard as a rock. Getting them out is a lot harder than putting them in. push down on the spring loaded pins with a nail or small screw driver,I use a sharp dental style pick to dig them out. Usually they will come out in pieces, but patience will prevail. Make sure the groove they sit in is clean. To install the new rings put some outboard oil on them and sqeeze them in the hole while pushing down on the spring loaded pins. These are fatter than a normal O ring, I got mine from a dealer for about three bucks.
