Rubber seal fwd of prop

[efizjb]

I pulled down my grate to reseal today, and the black rubber seal fwd of the prop has a crack/rip in it, and the seal is loose around the shaft. is this anything to worry about? My guess is when under way this seal is folding back or flopping causing cavitation. It's cracked like it is old and dry rotted.

I don't have prop tools, yet I don't want to take it to the dealer right now either....

Huge problem. How could it possibly be cracked or old???

This one part will fix your cavitation.

you don't need any prop tools to fix that. Just pull the pump off and you will be able to replace that rubber cone easily. You will just need to find them at your local dealer or online.

Damn it. Is it simply there to smooth out water flow to prop?

Am I correct in thinking I need special tools to change it out myself? The part I'm talking about is Kawi # 92093 best I can tell from parts breakdown on Skips pump stuffer instructions.

Why it is cracked like an old dry rotted piece is beyond me....

We must have posted at same time. If it is easy enough without tools I'll do it myself. Thanks!

I was looking at mine the other day and its all stretched out too, but no cavitation yet. Looking at it you would think its been on there for years instead of months.

I dont run with it, I removed it.Its been my experience there is a lil more speed with out it.

Thats interesting Harry, if mine has failed at under 20 hours, wouldn't make much sense to replace it to happen again anyway. I figured without it it cause a recess for water to create drag, but it seems for you to be the opposite...

I feel better after reading some of these posts I'm not the only one with dry rotted rubber parts on my ski! lol

With the ultra 150 it also increased speed to either trim them down or remove them completly.

Aren't we talking about the little rubber cone (with the opening in it for the shaft) that goes on the end of the prop? If that is not there, wouldn't all the packed grease etc get washed out from inside where the shaft meets the impellor?
