Help! Jet pump not working right!

« **on:** July 18, 2015, 02:04:05 PM »

I just rebuilt my energized jacuzzi yj and I'm at havasu. The boat barley planes. Does any body know what would cause this?

Check your intake grate first for grass/ect... could be causing little or no water with the blockage.

Havasu has been bad on jet boats with all the grass lately

I just checked There's nothing in there. It's been acting like this ever since I left the launch ramp.

Check for a packing problem sucking an assload of air. Otherwise... $:-\$

Did you forget to install the wear ring?

Exactly what does it do?

Do you have a droop?

A yj does not have packing but what's weird is that there is a little pin hole that I thought grease was supposed to come out of when greasing the bearings. But when the engine is off water is squirting out of it. I don't know maybe I need to frees it more? It's weird.

You said Energized YJ and yes it does have a seal pack, and yours has an issue...

Take a pic of the spot where water is leaking out... Once you stomp on it, the hole could be sucking air into pump.

Ya it has rubber seals. I agree it has a problem

« **Reply #10 on:** July 18, 2015, 03:16:56 PM »

Ya when its running no water is Cummings out so ya I would think that is sucking air. Is that enough air though?

« **Reply #11 on:** July 18, 2015, 03:19:27 PM »

The hole right behind the grease fitting

« **Reply #12 on:** July 18, 2015, 03:22:00 PM »

Is the hole threaded? If so put a bolt in it or plug it up an ck.

Take your clean out cover off(while on trailer/land) an see if you can move your impeller. Just to make sure the key is still in place.

Ok I'll check that stuff out and let u ou know. Thanks

What did you put the seal together with?

You cannot use petroleum products on carbon seal. Mineral oil or soap.

It's bad seals. Happened to be. Then the bearing went out cause it slung out the grease.

« **Reply #17 on:** July 18, 2015, 04:35:09 PM »

Ya the other hole in the front part of the bearings squeezed out all the grease. So I'm thinking that's probably it

I just used marine grease but this problem started from the minute I put it in the water

You cannot use grease on a carbon faced seal..... Instant damage.

I rebuilt mine. What are you supposed to pack the seals and bearing with?

Quality lithium fortified grease, but the seal if it has a carbon face cannot be contacted by petroleum products. You must use soap or mineral oil... Only...
