Impeller is stuck
Tried to pull my water pump impeller the other day, it's stuck in there real good. I was using pliers and all the leverage I could get on it. Any ideas? I'm thinking spray penetrating oil on the spline.
Also, my boat overheated the other day, hence I assumed the impeller was bad. I was feeling it with my hand, and all the vanes still seemed intact. Any idea what else could cause the overheating? I've never had an issue before with overheating in any boat other than a bad impeller. Is there a way to test if the motor is getting water or not? Maybe my thermostat is bad?Boats previously owned - 2000 Supra Launch, 2003 Outback, 2006 Mobius LSV

Check your water intake to make sure nothing is clogging it up. If it's not that then replace the Tstat and the impeller. Spray wd40 on it and then bump your engine over a few times and it should losen up.

I replaced my impeller earlier this year and what a pain it was to get out. I bought a can of silicon spray, similar to WD-40 and sprayed a bunch all around the impeller then let it sit for a bit. Came back sprayed some more then it slowly worked itself out. Took a lot of effort and getting any leverage is not easy, I think my forearm was bruised for at least a week. Sprayed the new one with the same silicon and it slide right in.
The overheating issue may be due to the impeller, not sure though. Is the oil good?2017 Centurion Ri237

check your transmission cooler. Weeds like to clog the screen inside that canister. For the impeller, spend the $ and get a puller from skidim.....money well spent.

spray WD40, bump the engine, and repeat. Worked like a charm for me. Check the water strainer if you have one, could be clogged.

the wd40 is the easiest way, I just help a friend change his. Just make sure to use lots of wd40. Then it will slide right out.

Use a couple of the paint can opening pry tools. I keep them in the boat with the spare impeller. They work wonderfully for leveraging those recalcitrant things out.
