Okay so I lost all power out on the river. Made it back to marina. Saw water between the jet and engine. Thought it was a freeze plug. (New to this rebuilding jets)

Pulled engine. Replace freeze plugs and packing bearings. Fire engine on stand and sounded completely heathy.

Drop engine in. Hook up jet. Get it all back together. Still doesnít start?? After I hook it up to the jet.

When I had the engine out I could spin the shaft freely?
I donít want to have to do a complete rebuild on the jet if I donít have to.

Shaft does slide about a half inch towards the bow and back. Also checked that when engine was pulled.

Please help if possible. It was my grandfathers boat that I inherited and Iím a mechanic but have never worked on a jet

mash on it

I think the tolerance on the front bearing is .002 to .004". Not half an inch (.500")

The jet pump is pretty easy and straightforward to rebuild.

Pull the hand hole cover and see if the impeller is digging into the suction housing.

Look up into the intake opening and inspect the impeller for the above mentioned digging into the suction.

Most importantly, check your oil for signs of bearing failure. If the shaft can move forward, it will kill the engine thrust bearing.

Good luck,
