We were on our 2004 sx230 dual engine and the Left impeller stopped spiningn...no movement.
Engine works fine. No issues
The heat light never went on.
And dud not have anything stuck the impeller shaft.
It's like a belt came off.

Glad to have you on board, sorry we had to meet like this :rolleyes:

How long have you owned the boat ?
how many hours are on the engine ?
have you ever got anything caught in the impellers previously ?

you've got a very unique problem that we don't hear about often, luckily it should be easy to diagnose,

you could even swap impellers/shafts from the good side just to confirm if your problem is in the intermediate bearing/coupler,

We are the original owners since 2004:)
No major issues, the usual, spark plugs, steering cables.
This is weird. No idea how many hours. I have had ropes, sea weed, a seahorse wedged and always been able to remove. This time No warning sign. I need to see if I can manually rotate the impeller.
Thx for the suggestion

Congratulations !! you may be one of our oldest original owner boats !

It would be good to find someone with a YDS near you and check the hours on your engines,


I need to see if I can manually rotate the impeller.
if something is broken maybe you can just spin the shaft easily,

if it's not broken this may be very difficult to turn, I believe you have to pull the spark plugs and then try to spin it at the intermediate bearing or maybe reach down through the cleanout tubes

it might also be time to take the cone off and check the bearings on your impeller shaft (but that wouldn't be the cause of no spinning)
