1993 GTX Issues

[Burner71]

Hi guys, I was hoping one of you could point me in the right direction to fixing my GTX.

So last month my wife was riding it and said it started running strange. I got on it and went to start it and it would disengage the starter right away after the motor started to turn. I lifted the seat and was shocked to see it half full of water.
The carrier bearing seized and was pulling in water.

Ok so i order new parts and and go ahead and change the wear ring with the pump off and replace the gear oil for the impeller.
So I put everything back together and I go to start it, it does the same motor turns about a revolution and disengages the starter. I thought maybe its the battery as it was getting older. I put a new battery in and it started up in the garage.
So I take it to the lake last night and in the water the starter is doing that same thing again, but finally starts.
Its idling good everything seems fine. I go to give it throttle and the first thing i notice is the throttle lever seems to have resistance on it like it didnt have before.
Next thing is the rpms are going up very slowly and it never gets to the top RPMS, stops accelerating at like 5800 or so.
I would let off the throttle and back on and again very slowly picking up rpms.

Then the overheat buzzer starts going off.
So I packed it up and went home.
Trying figure where to look.
It almost feels like the motor is binding somewhere. The new carrier bearing seems to be fine and its thoroughly greased. So im not sure whats going on or the corolation to the throttle lever stiffening up.

Any ideas?

Pull the plastic cover off the rear of the engine and with the spark plugs removed see if you can turn the engine over by hand.

i can, its tight but I can

I would try pulling the pump back off and see if the impeller spins freely.
Next up would be a compression test.

with the throttle lever it almost makes me thing the motor is being pulled or a mount broke maybe?

did it take on salt water? It honestly sounds like you're having multiple issues at once. The throttle is just a simple cable attached to a carburetor valve. Nothing about how the engine runs shoudl affect the pull on that cable. The overheating could be a blocked or unattached hose. Check all your cooling hoses by taking them off, checking for sand builup, shells in fittings, etc. Blow them out with compressed air to clear them and loosen any stuck debris. If you overheated the engine bad enough, you could have cooked a piston or two. If your starter is disengaging early, could be a worn bendix, or that your motor is producing enough of an attempt to start to actually disengage the starter. Are you sure you didn't run it out of oil? If you could take a compression reading, it would tell you a lot about the health of the motor.

never been in salt.
all this started after i replaced the carrier bearing. I have a feeling maybe its slightly out of align somehow?

so i took the pump off last night and when i pulled the water inlet hose off, the entire tube broke off the pump. Looks like it might have cracked when i installed the pump and to make matters worse, the silicone squeezed down into the crack closing off about 75% of the inlet opening. I assume this is why it overheated.

I pulled the driveshaft out. Hitting the start button, the motor does the same thing, turns like 1 or 2 times then the starter disengages or overruns.

May try to pull the starter this weekend.

Check that the starter is properly grounded to the battery,,.,the seal carrier will not affect the engine alignment,

So im replacing the starter now.
It went in fine then i noticed i appeared to be misaligned because there is 2 sets of holes?

Anyone know why there is 2 sets of holes for the starter??

Picture example:
