which water pump

[jessie11]

1992 Mariner V6 150hp<br />Ser# 0D124111<br /><br />Replaced water pump with all new components: impeller,housing the whole thing.<br />Did this with the help of a experienced mechanic. Purchased parts from a local Mercury dealer after giving him the above information. All went well and it works fine. Have since purchased a Seloc manual and was reading about the water pump replacement when something caught my eye.<br /><br />It said that motors from 50hp thru 200hp had a high volume water pump and it was recognizable by the shape of the housing. My new one looked nothing like this high volume housing.<br /><br />Do I have the right one installed? Am I in danger of a overheat problem? Any response is appreciated.

Well, it begs the obvious question, what did the OLD one look like? I always compare parts before replacing them just to be sure I'm putting in equivalent parts. Been burned too many times...

The old one looked like a solid round housing about a inch and a half high. This is the same one I installed. The manual shows the high volume pump housing is funny looking with ridges or vanes on top.

Re: which water pump

Manuals are sometimes hard to work with.I am a strong beleiver in Factory Original Ones.but I can understand them.Seloc,Clymers,etc,give decent basic knowlege,but have to cover too much in a small book.It will confuse you sometimes.<br /><br />Sounds like your pump had a plastic housing,a stainless insert,and an impeller about 2" dia.<br /><br />Seloc is showing you an alternative with a stainless steel housing,no isert,and about 3.5 inch diameter.<br /><br />Two different pumps,you put in the correct parts.<br /><br />DHP
