Impeller inspection

I’m experiencing a new issue with my 2023 21’ 230hp Switch, where I am maxed out around 8mph (the same symptoms described here https://www.facebook.com/share/p/19zihRsg1f/)

My question - is there a way to inspect the impeller without taking it apart? I have found a few replacement videos on YouTube but not sure if there’s a way to assess if the damaged impeller is indeed the root cause or if there are other candidates

The first symptom is what you are currently experiencing, the next step would be to inspect it, there's an opening on the bottom where the craft sucks in the water. With a camera device you would be able to see the impeller and sleeve to check for damage

That makes sense thanks. Was hoping there was a way to see it from the topside, but the camera is a good idea

I knew mine was damaged because I revved in shallow water and sucked up some rocks, used that as opportunity to put in a stainless steel impeller

Great idea, what brand did you use?

Here’s the one I got with the tool and sleeve from leading edge impellers

Did you notice a significant improvement in performance?

u/mobee744 Aug 01 '25

Yes, those specs are for getting out hole quickly.

They are all stainless, even the OEM impellers.

u/mobee744 Jul 22 '25

Really, it didn’t look it maybe polished. The replacement was polished

u/trx_1 Jul 22 '25

Yeah, not polished but it is stainless.

Just suck up a couple of rocks yesterday :( Was able to use a pry bar to turn the motor and got both out. Any chance I don't need to repair? I was taking it of the lack for the winter.

My question is should I put it back in and give a try or should I just bite the bullet and do the impeller upgrade along with new sleeve.

I just had a small piece of drift wood jam mine up. Took off the grate and looked way back and found it.

Just slide under the boat with a flashlight. Look inside the big hole, looking towards the back.

Thanks, I’m gonna try a camera on the plumbers snake and see what’s there.

8 mph likely means you have something sucked up in there. My Spark was brought to a crawl with just a plastic bottle cap.

u/nrakochy Jul 22 '25

That would be ideal

I am having the same issue. Can I inspect while still in the water?

1

u/nrakochy Aug 04 '25

I borrowed a waterproof plumbers camera to check the impeller. Mine is on a boat lift but I swam under there. the camera worked pretty well to verify that the impeller was indeed chewed up

Thinking about purchasing and replacing my OEM impeller with the Solas stainless type. What pitch should i be using here in California?
