Mercruiser water pump

[smithrock]

Well, took the boat out today only to find water squirting out the weep hole on the back of the water pump. I have an '85 262ci. 4.3l V6. Can I replace with an automotive water pump or does it have to be marine? Does anyone know the part # I would need?

Re: Mercruiser water pump

You'll need a marine water pump for the proper connections. If want the part number, an engine serial number would be helpful.

Re: Mercruiser water pump

I'll try and get it, engines still hot. Where exactly is the serial # located?

Re: Mercruiser water pump

The serial number tag is located near the STARTER, by the flywheel housing; or, on the ROCKER ARM or FLAME ARRESTOR COVER. It should begin with a zero followed by a letter (example 0A123456)

Thanks again!

Just hit ebay or another online retailer - your V6 uses the same water pump as the small block V8's, you really shouldn't neeed a part number to find it.

Re: Mercruiser water pump

Anybody on if this is the correct water pump (see above post)

Re: Mercruiser water pump

That was the correct pump.

Re: Mercruiser water pump

Well I took off the bad water pump only to find that there was a small hole on the back plate from corrosion and the pump looked to be an automotive pump. The impeller was metal as was the back plate. I got this one on ebay, is this one correct?

You are bidding on a BRAND NEW 5.7L (350ci) MARINE WATER PUMP. This is the exact model used in Volvo, Mercruiser, Indmar, Penta and other high-end marine engines. This pump is built with a bi-directional internal brass impeller and stainless steel backplate to withstand heavy duty wear in even the most strenous open water conditions. This new model will fit on a wide range of standard engines including 4.3L (262 ci), 5.0L (305 ci), 5.7L (307-350 ci)

Sounds good to me.

Sounds good to me.

Thank you very much! Should I take off the back plate when I get it, to make sure the impeller will be turning the correct way? Or since it's bi-directional I don't need to worry about it?

Great! Thanks!

I'll have several more questions to come, as I change things out.

Re: Mercruiser water pump

Okay, I already have another question: since I have the water pump off, should I put anything like Salt-a-way or something inside to clean out anything?
