Hey can anyone out there tell me if the lovejoy coupler on the jet pump side is supposed to have any play in it ? I can grab it and move it up and down 1/16”. I’m talking where the 2 couplers join on the pump side inside engine bay. It doesn’t seem to me any bearing should have any play in it but just looking for some good news 😆

Shouldn't have any play up and down, if it is sloppy when turning it is probably the rubber damper
 
I have not yet had the pleasure of needing this job, but with that piece being pressed into the bearing, etc. that is indicative of failed/failing bearing on the pump side of that coupler. I would suggest watching carefully on next outing and keeping an eye for water ingress or suspect noises. I hope I'm wrong!

I had the same issue with our 06 SX230, there should be little if any movement in the the mid shaft and bearing assembly. I replaced both of ours and it solved the problem.
 
There is a vibration dampener rubber coupler that goes between the two parts it wears down over time and you need to replace it 1744071512751.png
number 36
Rubber Shaft Coupling
part number
66E-4581J-00-00 And while you are in there replace the intermediate bearing housing also

Even with no dampener in place, the pump bearing side should not move right??

That's why I think it's not the dampener.

you mean have slop in it no it should not but if it does the seals may also be allowing water in the pump it the bearings are bad so remove the cone and see what the grease looks like in the pump
 
The OP has left the discussion I believe
