PTO Troubleshooting 93 GTX

[SurfBeat]

While cruising up to Parker Dam my damn Doo stopped.

Upon depressing the starter button all I heard was a THUD noise.

I towed it back to the Windmill resort, checked the battery, shorted the solenoid, pulled the starter. All worked okey dokey.

It was getting dark, so on a lark, I pulled the plugs to check for hydrolock and when I depressed the starter button the Doo cranked over easily and fortunately no water came bursting through the plug holes.

This morning when I tried to start it all I got was the "Thud" again.

A guy at the trailer park suggested I try to spin the PTO flywheel. When I tried that the darn PTO flysheel would not turn by hand. It would not move unless I applied a lot of pressure with a pipe wrench. The Zerke fitting made using a pipe wrench difficult.

I quickly checked the jet pump opening in the rear of the Doo and found no debris.

My advice giver has left for home, so here I am, up the River and no where to go except to the Forum. That could be a good thing.

QUESTION: Can a jet pump cause this problem? If yes, how do I verify that I have a jet pump problem and not an engine seizure.

Darn, I guess my post was not lucid. Let me now make it crystal clear.

1. I exchanged the battery from my non-running 93 Doo (subject of thread) to a running 92 Doo. The 92 (working Doo) cranked over fine.

2. When I put the battery from the 92 Doo that worked into the the non-running 93 Doo. it did not crank over.

3. I did remove the spark plugs today and tried to start the 93 Doo? It did not crank.

4. I was cruising down the Colorado River yesterday when it stopped all of a sudden, like running out of fuel.

5. When I depressed the starter button, all I heard was a THUD noise from the engine compartment.

6. I towd the Doo about a 1/3 mile to the dock, facing forward as if I were riding it.

Last year someone swiped my drain plug and while taking off my engine compartment flooded. I did not know a damn thing about hydrolock, so, when it would not crank over, I heard the 'THUD" noise. A few weeks later a friend came by and pulled the plugs; swoosh, water came spurting out.

An hour or so later we got it started, took it out for a long ride and it workded fine.

When I took it out last week it worked fine.

Other than fogging the cylinders and putting fuel stablizer in the gas tank, I haven't done any other maintenance in the past two years.

I read that I should drop some oil in the jet pump and last week I bought the oil and other stuff needed to do the job. Maybe I was too late and the pump froze?

Hopefully the foregoing will help you formulate a plan for me so I can get this Doo back on the River next week.

As I kick back reading your reply on the other side of Parker Dam from you, I wondered: how does freezing of the pump effect turning the PTO?

Doesn't the engine turn the PTO?

Should the impellar in the jet pump turn freely, or does it need power from the engine to turn it?

Let me grab some lunch and my Clymer's manual and will look forward to your reply.

Does the pump freeze at the engine or in the rear of the Doo?

In other words, how can I determine if it is the pump the freezed or the problem is in the engine?

Thanks. I'm fetching my manual and then endeavor to remove the pump.

damn joey...was just there, from weds-sat night. if you were cruis'n/rip'n along and all sudden stopped, then i wouldn't waste time pull'n the pump but, pull the motor.
