Superjet starter shenanigans

Hello, I am the unfortunate new owner of a 2001 superjet. Apparently this ski was reliable as hell and it even started in the guys garage I bought from, but as soon as I got is home it was apparent that the ski was electrically fried.

Replaced teh start/stop lead in the ebox, replaced every 4 gauge cable, fixxed all the broken wires in the ebox. Still wont crank, so out comes the starter motor and it just throws sparks on the bench. I can't find a single Mitsuba trademark on this thing so I assume it is aftermarket crap, but apparently this motor worked for over a decade somehow.

It looks fine and I even tested the armature, everything seems to be dialed. I don't know if its worth reassembling though as something is obviously not right.

Now I have a used mitsuba Sm-13 on order, it looks clean as hell, no rust. i'm trying to find a rebuild kit for it, and I found this http://www.stockers.com/index.php?dt=SM-13

What sucks is it appears to just be the brush holder and brushes, doesnt even picture the pos post o_O

Is there anywhere to get a complete rebuild for the OEM starter anymore? Does anyone know of a kit that crosses over from like an ATV starter?

Last question, is the Sm-13, which I believe it the stock superjet starter, is it a 4 pole or a 2 pole motor?

Thanks for the help, Im not usually so wordy but I have been tearing my hair out over this thing. I don't even care if I ever get this thing in the water, I just want it to start 1 time in my garage.

That's an a/m kit. Suggest you wait til you receive the used Mitsuba you ordered. If it looked really good on the outside in the pics, It might be a good one. Take off the tail end, make sure the brushes have at least 60% life left and are not stuck. Pull off frnt. cover and make sure no "fretting" is visible on the armature shaft ( caused by a worn needle bearing). It would help to put bearing grease on the needle bearing, the rear bushing will likely be very dry. It is/ should be an oil lite bushing- which means it can absorb some lubricant and retain it. Careful here! just a wee bit grease! The grease has a nasty habit of finding it's way to the brushes and softening them- maybe that's why that bushing is pretty dry on a new one.- You prob. wont need that a/m kit!

I’ll add, first bench test the used one when you receive it, to make sure it spins......Before doing any work on it..

Just thinking of the transaction between buyer and seller...

When I was a service writer we had brand new never ran superjets go bad on the sales floor and not start when they were getting prep'd for delivery.
