Ok thanks @BruceSki @JetManiac
Yes, but the single rear seal in the raider housing should be replaced with the 2 rear SJ seals.

Yeah that'll fit
It will fit, but make sure housing isnt separating, it looks salt crusty and also that the splines are good otherwise worn midshaft splines will wear out your driveshaft splines quickly.

FYI, the intermediate shaft housing and bearings from a XL700 appears to be the same part as a RN SJ, The shaft is much longer and will have to be replaced with the shorter SJ shaft. I saved a bit of cash by buying one of these off of eBay for less than 40 bucks as opposed to the SJ intermediate shaft housing, which typically run much more.
The housing is the same, but the rear grase seals setup is different and should be changed for use in a superjet.

Huh, it appears to vary by year for the XL700s - I just went and looked at my '02 XL700 and it has the newer 2-piece intermediate shaft housing like you are describing. The piece that I got supposedly came off a '99 XL700 and appears to be identical to the stock one on my RN SJ.
The XL midshaft housing is part 7 in this diagram. The part 5 does not exist in Superjets and Blasters. It seals the midshaft housing to the large pump tunnel directly, so eliminates water from the rear of the housing and Yamaha only used a single rear seal (part 13).
In a SuperJet or Blaster, however, the center of back of the midshaft housing is directly under water during use. Because of this water exposure, there are 2 rear seals in the back, both a single lipped one like in the XL, but also a sturdier double lipped seal designed for direct water exposure.
Highly Recommended and yes.

So, if I'm hearing you correctly, the seal setup on the housing on the right is not the correct one? The one on the left is my old one and the one on the right is the replacement and to my eyes they look identical. Even the inner bearings appeared identical prior to putting in the shaft.

Most of your midshaft housings with the longer midshaft have a wider bearing, @JetManiac knows his poop

Now that I stare at the pictures, I'm starting to see the difference.
The old one on the left has the wrong seal in the rear. The one on the right has the correct seal in the rear, but you can't see if the inner seal is there with the shaft in place.
