I am installing a lower unit seal kit, part 18-2686, on my '55, 25 HP, Big Twin.

I have located all the parts in the kit, with the exception of the Shift Rod Gasket, part 18-0882. It is the black flat fiber washer.

There is no indication of this part in the original OMC parts manual, nor have I run across a location it would work.

I am either missing something and need your help, or this part is included in the kit for the use in a different motor than mine.

Does anyone know if I need this gasket, and if so, where does it go?

Thanks

The gasket is used with the shift rod bushing where applicable.

Perfect, thanks HighTrim. Looks like mine is a type one, no wonder I couldn't find where the part went. I really didn't want to close it up with the "extra part" bugging me.

Now, on to a carb rebuild and ignition check.

Have you checked pistons / rings / compression on this motor ?

No, this is a running motor I winterized a couple of years ago and put away till the boat hull was being restored. The hull will be ready this summer, so just doing some basic maintenance.

I will check the compression, but it was fine when I put it away.
