Extreme cavitation

[shootawave]

Does extreme cavitation make the craft hard to get on plane and also make it feel as though it has a slipping clutch type syndrome. This is what my 99 GTX Ltd. is doing amongst a few other weird things all of a sudden.

Not sure if your craft has the neoprene seal that goes between the jet pump and the hull. If it does, once the seal is worn, you lose water pressure through the pump and until your craft planes, it is very slow. I experienced this myself this year.

If the seal is worn, it's only about $8 to replace.

Other issues that may be present are:

-Worn or damaged wear ring
-Impeller damage
-Seal between pump and hull not adequate (could be neoprene or RVT)...check the manaul for your craft.

You definitely have some sort of pump pressure issue.

Thanks, GODDO
I took a further look and it does appear that part of the neoprene may have melted? Shooting too many waves?, a little overheating maybe?, this may also explain the extra water in the hull (lots). Being in Hazmat I have some very high quality neoprene in 1/8 thickness, do you think i can use this and just cut out a template?
Thanks again!!!

Definitely...If you can make it fit, and the thickness is equal to the factory part. As long as it seals and doesn't affect the pump/shaft tolerance then give it a go.
