Need help with exhaust pipe to gimbal o-ring P/N

[GaJeff]

I have an 81 merc 4cyl. just got done doing a resto and putting the engine back in. Im having a hard time finding the P/N for my exhaust to gimbal o-ring. Al the ones ive found look like an upsidedown "U" and are for V engines with a Y pipe. I have a single pipe and my o-ring is an oval.

Does anyone know the P/N for the oval o-ring so I can get this thing ordered and move on?

Thanks, Jeff

There should be a groove for each (all 3) in the gimbal housing... If one of the small ones leaks, it'll fill the boat just as quick...

My pipe isnt big enough to cover the lower o-rings... Actually its just two holes at the bottom, no groove and the bolt holes look like they were never tapped for threads. My downpipe only has 3 bolts holding it in and it all fits perfectly over the hole.

Thanks for the P/N Jeff

I double checked my holes and the lower holes go nowhere... The o-ring in the link above should be the correct one right? I guess my downpipe is different because its a 4cyl? Also I assume the lower holes exit exaust out the side of the gimbal housing? Mine collects at the main and have 2 holes inside that route out the sides. I ordered o-ring #13 so hopefully it will be here in time for the weekend... Im so ready for a boat ride the wait is killing me

Yes, you just need the one O-ring. The two small O-rings are only used on V-8 setups.
