Thread: Water Pumps

Ok guys my boat dealer is out of business in Nixa, MO, Walts Boats and Motors. Where is the best place to get a water pump for my 50 HP 2 cycle Mercury and is it something easy that I can replace by myself? I have heard of places around Springfield charging as much as $125.00 per shop hour. What kind of info will I need to get the water pump? How offend should you change a water pump? Boat is a 2008 water pump never replaced.

Yeah you got yours Clift after I got mine I think. Yours has an hour meter on it?

Hey are you bringing Harold? PW58 was thinking about bringing a wheel chair for him with a stuffed womans body in it!

Most are easy to change, unbolt the linkage under the motor head going down to the lower unit then unbolt the unit and slid it off the motor. The water pump itself is pretty simple to change , there are only a few parts to it. Good Luck.

Bigby with my luck there is nothing easy! But I watched a YouTube video on a 75 HP Mercury showing it done. The guy never unbolted any linkage under the motor head. Just unbolted the lower unit and undid about 4 bolts. Hey PW says she is making you guys Jello shots for fall camp!

Change the water pump and do it soon. Your boat has set a lot and this causes rubber to dry rot. It is a cheap part until it fails and you are replacing an expensive powerhead. I change mine every February, along with the lower unit lube and seals. Have everything checked out and good to go. I figure you can have all this done for less then you spend on oil changes for your truck in a year and you wouldn't change your oil once every 3 years in your truck would you??? Can't help with a mechanic close to you but I know a good one in Carl Junction if you don't mind a drive.

I changed the water pump on an old 75 hp merc I had....by old, it was probably about an '88. Anyway....I thought I was reasonably handy with a wrench....you know....righty tighty and lefty loosy and all that. I learned one lesson....fork over a couple bucks and have that bad boy changed by someone who knows what they are doing. There are alot of things going on in there in terms of linkage and I swear I put it back together and took it apart about 30 times. I finally gave up, had a beverage or two and went at it the next day. I finally got it all back together and then the dang thing overheated on me anyway and torched a cylinder.

Good luck....Sorry I don't know any decent mechanics near Nixa.

Tom I hear you! Thats what I worried about! Remember I am the nut case who has State Farm Insurance on my boat that replaces the lower unit!

Sevenfiftynine been there and done that on farm equipment! Be told at the farm equipment dealer hey you can do that! Then end up making 2 trips or more to the dealer who is 30 miles or more one way away from the farm. They seem to always forget to tell you that you need some special tool to undo one bolt!

Here is the video that I found online:

How To Replace Mercury Outboard Water Pump Impeller - YouTube

Water pumps are pretty easy. Just Unbolt the foot and slide it off the driveshaft. The water pump housing is right there. Take the cover off of the housing and slide the old impeller off. Slide the new one one. New gasket then put the cover back on. Put the foot back on the drive shaft and bolt it down.

Hey Dan the guy who works on my boat says every couple of years. I will text you his contact info, great guy and very reasonable.
