MY raw water pump quit last season and I plan to pull it and either rebuild or replace.
Has anyone fooled with a shurflo? Does it make sense just to replace it? Should I look at other brand pumps as well? Any input is appreciated. Thanks, Jay

My job requires using shurflos to transport water with chemical added.

Not sure what type you have, but over time,the chemical, eats the diaphragm and won't pump, even though the motor is fine.

I know you don't pump chemical, but debris and bad water quality can eat a diaphragm as well.

If you have the same type of shurflo (1 gpm non submersible) then i may have a diaphragm kit for you to try before you replace.

The pressure switch can also go bad and it can be replaced for cheap.

I think I have a combination pump, live well and raw wash down. the live well works but the raw water just quit. I think it could be a pressure switch since the live well still works???? I guess the best thing is to pull the pump. If it is a combo pump I will probably switch to two independent pumps. I only saw one pump in the stern on the wall. My fresh water pump is in the forward compartment near the bow. Very little room to get your arms in there. The live well is in the way pretty much. First nice day I will get a better look at the area and follow the hose lines. The boat is in the water, at my marina. I did not have a flash light with me and it is poorly lit in there and crowded with all kinds of crap and wire terminal blocks etc.~JJ~

tap on it with a hammer. The pressure switch sticks all the time.

check out marine service center up on hwy 9. I heard they have some sort of insurance plan for pumps and such that sounded pretty good when i heard it. might be worth checking out.

Thanks for the tip about tapping it with a hammer, I have to do that all the time with the starter on my lawn mower LOL. And Hey Lumberman, I have been waiting for the weather to change and the water to warm up. I think everyone has cabin fever. I want to get back on the water real bad. I need to do a little TLC on the boat and then be ready for the spring.~JJ~

Buy a new one and replace it. Fix the old one if possible and have a back up. It sux not having pumps

That sounds like the best solution, get a new one and rebuild the old one. But I will first try the hammer trick LOL. ~JJ~

Is it the aqua king? if so, that is a fresh water rated pump. The blaster and pro blaster are the saltwater rated models. Going through the same thing myself.
Blaster 129.00 plus shipping.

The pump is for raw water washdown only. You have a separate live well pump. Probably looks like a inline bilge pump. It is a bugger to get it out though. I am talking about the wash down. I would replace with the same pump. ShurFlows are good and dependable. Would get the Pro blaster model Shurflo though for some extra zing. I just replaced mine last year after 8 years. And came to find out that there was some obstruction in the line. My bad. Is the pump still running? If so you might want to make sure the line is not clogged. It is amazing what grows and can get in the line. As difficult it is to get to, you don't want to have to change mounting holes and wiring in my opinion. And again they are good pumps. After all it is what HS used originally. Luv my 2390. By the way-do you have any fuel burn numbers and WOT with the 4 stroke??

Fishnncblue, Thanks for the info. I know it must be a pain to remove it. It is extremely tight in there.
I think I will go with the Pro-blaster this time. It has a blaster now and did not really have much force when cleaning blood. As far as fuel burn numbers, I hardly used the new motor last season and never much paid attention. I will be figuring my burn early this season as I hear gas will hit 3.50 /3.75 at the marina's this season. ~JJ~

FISHNNCBLUE, you were right it has two separate pumps, It turns out the waste water pump is a "ProBlaster" not a Blaster. So I need to pull it and replace it. I might also rebuild the old one as a back up. Thanks again. ~JJ~

I usually buy my boat parts online as well. I have saved a lot of money shopping the internet.~JJ~
