Yamaha midshaft assembly identification

[ChuckBiscuits]

I bought a hull with a custom driveshaft and a midshaft assembly from an unknown model. Can anyone tell me which model this midshaft assembly may have come off of? The numbers on top of the assembly don't seem to match any part numbers that I can find online. The assembly is going into a standup and I am trying to verify that it has two rear seals like a superjet.

Also, if it does have a single rear seal would I be able to disassemble it and press two new seals into the back?

It is probably from a 1100/1200 sitdown.

What hull is it, that might help you if you tell us what hull?

It's going into a PJX hull, which is superjet based but requires some adjustment to the driveline length. The 65A prefix is confusing me since I can't find any reference to a 65A type engine.

Not trying to be a prick, I just come off that way.

But I did a quick google search and found a lot on the midshaft housing. Which is really what your looking to find info on. Compare it to pics online. Look up a seal kit for that housing number. Then see if it's (the seal kit) the same part number as a seal kit for a sj.

Thanks, I appreciate your help. I had seen some of those before but was thrown off because the photos showed 65R or 65U instead of 65A.

Understandable. Custom builds can be confusing. But well worth it. Often times I'll use google to search what I'm looking for and type "x-h2o" at the end. Then it will give you quite a bit from This site. And this site rocks

Yes, you can press out the shaft and then pry out the rear seals. Replace them and then reinstall shaft.

We have the seals if needed.

Thanks JetManiac, you're awesome. I'll be contacting you soon for seals and some other stuff.
