Transmission fluid leak at the linkage

After floating around these forums for a little over 2 years now and reading through many maintenance threads to help a buddy with his boat, I've finally taken the plunge and purchased a Ski Nautique.




It's an '83 SN 2001 with a PCM 351 and Borg Warner 1:1 trans. The transmission and top end of the engine were redone by the previous owner approximately 3 years ago. Buying it, I knew there were a couple projects that I needed to tackle before the season kicked off. Especially since it had been sitting for 2 years.

This weekend I will be doing all the basic maintenance (full fluids flush, filters changed, belts/plugs/impeller/soft hoses replaced, etc.) but also want to look into a transmission fluid leak at the linkage. In this picture, you can see the fluid pooling up towards the back. Running it for 20 minutes left a small pool in the bilge.



Before posting, I scoured through the forums and found this:

Topic: tranny fluid/pressure

Eric's response on that led me to order Item Number: 92908 and the gasket for the NSS cover so hopefully that fixes it.

My questions are:
Is there anything I should know going into this?
Is there anything else that should be replaced/inspected around it?
What other seals should be replaced/checked after a boat has sat for awhile?


Thanks in advance, and hopefully this helps someone else in the future!

Ryan nice boat and welcome to the site. I just discovered the same leak, will be tackling it soon. Good luck!

Zach,
This surprises me since there are 933 standard O ring sizes in the AS568A system.

Yes sir




I know its weird Pete. I tried 3 or so different brands of similiar sized O rings and the thing leaked every time we put it back together. The only reason I tried locally is because it needed to leave that day which didn't end up happening.
