Sorry mate I own one and they were definitely broken stator veins on mine

Jappa is correct, they were made like that from the factory (and yes he has one also!)

PIC of a brand new one attached

Ok guys so when you look at the stator
and you find radiating cracks and fingernail sized irregular
pieces of stator chewed away
then this is all perfectly normal???

Yep, after 1 hour in Karls hands they all look like that . Would be hard to tell what the original profile was.

Just finishing a 3m jet boat with Kawasaki 900 running gear and have forgotten how it was plumbed up.
Can anyone tell me where the hose off the 3/8" outlet from the bottom of the exhaust expansion chamber is meant to go too? is it just out the back of the hull? if so what stops water from going back in when parked up,
Any help greatly appreciated.

hi fuge,
i think there is a fitting somewhere on your engine that feeds water into this fitting. at least thats how my polaris is. see the hose in the bottom left of pic...

Thanks Heemi

From what I can see the fitting on the top that you are showing has a hose from the head to here, this is where you are meant to insert the garden hose to flush it ( this i dont understand as it would go straight out the exhaust ) .
The fitting I am lost with is out the bottom of the cast exhaust just before the hose to connect to the muffler box.

if the 900 is the same as the 1100kawi i'm pretty sure the hose you are talking of just exits out the back of the hull beside the jet unit. My 1100 did and i just copied the same setup when i put the running gear in a boat. There was another hose coming off the top of the exhaust which tee'd into 2 pipes, one fed water into the muffler and the other went through the over-temp sensor and then out the tell-tale on the side of the hull.

cheers jeff thought that might be the case, any idea what stops water flowing back in when at a stand still?

[Jeff B]

Nothing, i think it's just the water jacket outlet. It can't get up into the engine as the exhaust goes up higher.

[glocko]

think that one is plumed into overheat sensor then back into exhaust or overboard.

question on the intakes from jet skis.

is it better to fab one from scratch or remove one from a ski and modify it?

Just looking for opinions and pics of some built.

Thanks!
