Plastic raw water pump body
 

I found my water leak. My raw water pump body is split wide open. Has anyone else found these split or cracked. I replaced the impeller at the begining of the season and it looked great. I used the proper torque and everything. Just woundering if I should simply replace it with a new plastic one or get an all new brass pump assy.

Thanks

i have been told its quit common if you get alot of "air" replaced mine long ago with a brass one

Thanks trubo2256. That's kinda what I thought. The money pit strikes again!

The brass are very good, but the plastic is also ok. The key to not breaking them is to tighten them like a car tire and do it slowly. The torque on them is very low like in in/ft pounds.

Good luck

My plastic pump bodies are both pitted. The pits are in the body around the in/out ports. Impellers seem to last a normal amount of time (a couple of 25-hour seasons).

I do plan to go to the bronze body pumps at Procharger time.

SeaDated,
I have a plastic body that you can have if you want it, it is 1 year old (used 1 season). I later had a pump problem and replaced the whole thing with the bronze assembly.

pachangalpina, Thank you!

Just split mine top and bottom last week. I could not figure why it would break, so I assumed I over tightened. As stupid as this sounds, I think I overtightened the hoses, atleast that would make the most sense from where the craks were, and recently I had the hoses off to make room for some other work I was doing. I replaced it with the plastic housing, becuase this was probably my error, not the part. WHile you are in there, spend the extra $25 and put a new impellar in as well. My .02

Allan4...Already bought the new impeller. Good idea. Thanks

Is the bronze unit a mercruiser part or is it the unit manufactured by Jabsco? Part #'s??? Thanks

Did I miss something here???? $25 for an impeller? Is it gold plated?

Yeah, Buck; $25 US for one of those impellers is not a bad deal. Wait till you need to buy one in Canada RIGHT NOW cause your'e on vacation, on an island, and the only guy you can paddle to that has one says he can help you out for about $60 Canadian. Oh, by the way; he had a couple of scrunched gaskets that he figured he couldn't sell so he generously thru them in. And I hope you know I'm talking just the part here; I did the labor!!

I guess I need to go look at the reciept from the last one I bought. Seems like I was giving around $10 for them.

I have 2 new rebuild kist if interested. Includes new one piece body, impellors, bolts & necessary gaskets. E-mail for info. [email protected]

Its a Jabsco retail price was just a bit less than Merc one best price I have seen so far was from Boat US. Impeller can be replaced without removing the pump just the rear cover.

I replaced mine with the brass Jabsco. I had the back plate machined to accept threaded AN fittings. Now it's all expensive plumbing:p Oh well, no screw clamps to dink with and it looks good.

The original post said "has anyone else found these cracked" I recently took my boat in for a new distributer cap, wires, plugs, and some other stuff. I took it out to the lake and was overheating before I got to the no wake bouys(spelling?) Morons had run it dry to the point of obliterating my impellor and housing!
Duh...which kind of boat is it you can run out of the water???
NONE!!! :D

SeaDated,
I had a hairline crack in one of mine. It only had a couple of hours on it. It could have been from over tightening. I had the Marina send it to Merc. They replaced it with no questions asked. I wonder if they had a bad batch.

Could be a bad batch. I better watch the other pump closely. I'm so glad that pump didn't break when I was crossing Lake Ontario. I think I'll purchase an extra pump housing just for safety.

Ran into a guy in a Talon running the Black lake in northern Mich
boat would run over 100 with blower big block carried spare water pumps with him cracked housings all the time. Thats when I started looking for a better one.

the jabsco part # is43210-0001,you guys need to carry a spare kit for the mercruiser.....we went through about a dozen of them in the race boat during the last two seasons.....dont want to cook your motor for a lousey 90 bucks.......and always,always replace these things as a kit....

Sierra has a kit for the Merc Water pump/fuel pump assembly. Part # 18-3150 includes plate, impeller, plastic housing, o-ring and bolts. Lists for around $85 but you should be able to fiind it discounted (I paid $48.50 at a friends bait shop)

Quality looks similar to Merc. I've got 150 hours on it with no problems.

BTW; I carry a spare:rolleyes:
