I did that and didn't feel like there was anything there. Should I try harder?

Also, the water doesn't feel like its shooting out as fast as it should be. Is there a way to clean that?

You probably sucked up some weeds or plastic bag. If you don't find anything through the clean out port you may want to put it on the trailer or swim mask it under the boat but it does sound like a classic debris scenero.

Check the cooling water intake. Its the small square thing in the left (if your facing the back of the boat) and make sure it is not covered. small crap can cover it and ruin a day. I'll look for a pick.

Agreed. If you decide to swim mask it, be extremely careful that you do not get your hand/wrist caught in the intake and watch your head as the boat moves up and down with wave and/or wake action - either case is potentially deadly.

Totally agree with @Julian You have classic signs of an obstruction in the impeller/pump. It could be something wedged between the impeller and housing or wrapped on the shaft. Put the boat back on the trailer and grab a flashlight.

Yep, don't know how many times someone has checked their pump and not found anything, then got a bright flashlight out or pulled the pump, and discovered a small piece or driftwood or something similar. Loss of thrust with vibration = cavitation. Pulling the pump isn't that hard and easier to determine what is stuck in there. Be advised that it is common that once you pull the boat out of the water, driftwood can dry and shrink, and actually fall out! Making it hard to determine what was the problem.

@aaron jansen This could also be some fine fishing line - wrapped around the shaft - may be difficult to see/feel.
I'm surprised you did not get the customary overheat error code.

I agree with the above advice. Sounds like a classic case of cavitation. You're looking for something as small as a toothpick or piece of fishing line wrapped around the shaft. Also, it's possible that some silicone came loose on the intake. Good luck, should be a simple fix once you find the culprit.

If you can get the boat on the trailer so you can look at the shaft directly. If you are lucky whatever is causing cavitation has already fallen out or will when you pull the boat out of the water. It could also be a something like fishing line wrapped around the part of the shaft you can't see or easily feel though the cleanout port.

Thanks everyone, I am going to get this thing on the trailer and will update. Appreciate all the responses.

If it is the pump, is that easy to remove? There is a marina nearby I can possibly borrow some tools from.

Where is the rest of that impeller and what damage did it do on the way out?

WOW....and no damage on the leading edge of the other blade....so it looks like it just broke off! Check you pump for other damage!
