Hello, every one.<br /><br /> I have 40horse 1991 johnson. I drained the lower gear oil and looked a little milky. I want to replace the two seals, went out and got a tool called the puller part#378103. The two long brass screws that came with the tool does not fit the two screws holes at the lower gear. Now what do I do ? For me to take out the propeller shaft bearing housing, do I have to replace the O-ring also. And how do I put it back after I am done with every thing ? Do I pound it back in slowly ? Please help....<br /><br />Thanks, so much.<br /><br />Matt.
