Mercruiser 350 MPI Seawater Pump Impeller Replacement

After experiencing a low water flow and overheating alarm, I replaced the water pump Impeller on our Mercruiser 350 MPI.

Wow, Great video, Yes you pulled the engines water pump. Your boat really needs a salt water cooling system. Love you channel and all of your great videos.

Thanks Garrym09…. We have learned a lot in the last year.

Very informative video. Thank you. I suspect mine has an issue. Leaking. All the extra hints will help with preparation. Great camera positioning also.

Thank you for all of the constructive comments. I try to make the videos as informative as I can.

Winston is such a good helper 😂

He keeps things from blowing away

[@Daniel_gamarra]

Dude thanks. I Watched your video and also though the recirculating pump was the water pump lol

[@RandomlyAwkward1]

I took it off by accident but actually found out that it was easier to do the water pump repair with it out of the way!

[@alanireilly2596]

Would dipping and cleaning the pulleys into the phosphorus acid not remove the lubricant from the bearings inside? 😮

[@RandomlyAwkward1]

Hey Alan… yes you are right. I only dipped the part without the pulley into the Phosphoric acid to clean it.

[@user-nk8qu7rd2b]

Did the acid you used to clean the casing cause any damage to the bearings? 😮

[@RandomlyAwkward1]

No it did not

Had the same thing happen to me last weekend, hope parts of the impeller didn't get into the engine.

[@RandomlyAwkward1]

That’s a great way to ruin your day, Jose… if you are missing any rubber pieces, they are probably circulating in your heat exchanger if you have a closed system, or you may have spit them out in your exhaust. The repair isn’t difficult, just impossible to get to in my case.
