I just purchased 2 SeaDoo ZS05 GTI Scooters on Craigs List and I'm trying to get them going. One has a bad gear box but I think it can be salvaged. One of the bearings was shot. Has anybody else replaced the bearings in one of these units? I'd like to get some confirmation of the sizes I came up with. The other one just has bad triggers so If I can fix the gear box, those will be an easy fix.
Best I can tell is the following
Small bearings at either end of each reduction gear is 10mm x 3mm x 4 mm (Micrometer shows 0.393" OD x 0.1175" ID x 0.161" Thick) which makes it a 623-2RS
Large bearing for the drive shaft is 19mm x 8mm x 6mm (Micrometer shows 0.750" OD x 0.314" ID x 0.235" Thick) which makes it a 698-2RS
Medium bearing for the gearbox end of the drive shaft is 14mm x 5mm x 5mm (Micrometer shows 0.557" OD x 0.1955" ID x 0.1965" Thick) which makes it a 605-2RS
I found all these on Amazon and I was able to order enough to completely rebuild both gear boxes for about $25.00.
If I'm successful I'll post the results and specs for everything on here.
One thing I have noticed which looks like a bit of a design flaw is that two of the reduction gears rub against the gearbox housing and eat out a small relief in the plastic. One goes all the way through. Not a major issue but if it ever flooded you would definitely get water inside the gearbox itself. It's not meant to be watertight, but this makes it definitely NOT watertight. This was on both of the ones I got so it wasn't related to the bad bearing.
If anybody has any experience / tips regarding this, please let me know

This is the shell of the gear box that had the bad bearing.
