View Full Version : Bilge Pump Mystery

09-10-2006, 06:10 PM
Ok so my bilge pump was needed today and did not work. Skied with a bilge full of water, but we managed. Back in my driveway now with the plug out and the bilge empty, thinking I need to pull my bilge pump and declog the suction side of the impeller. Hmmmmmmm? I can't seem to figure out how this thing comes out of my 88PS190. I've pulled the access cover and have tried rotating it to the point I'm afriad I'm going to break something. I see no visible screws or retaining device. Anybody got a suggestion on how these things come out? Mine is yellow, with the auto float right next to it (yellow also). I believe it is factory. This thing will not budge.

Could it be snap in place on a fix base?

Tri spinning the yellow pump housing clockwise. The yellow portion should separate from the mountingplate/screen. Obviously counter clockwise to re-install. Sounds backwords but should work!;)

Yea the factory is opposite rotation to set in, and you'll want a pair of rubber gloves if you don't clean your bilge very often.

Well don't I feel smart. I guess the righty tighty lefty loosey thing isn't applicable in every case. I turned it clockwise and it came right out. I am now on a quest for a replacement as this one is shot. Hopefully I can find one that will screw onto the same base.

Thanks for the help

If it is still the factory pump it is shot and you are wasting your time to try and get it working. Go to Boaters World, West Marine, SkiDIM, etc. and buy a replacement for $50. Once you get the new pump it will be obvious how to take out the old one.

This is an easy evening project you should be able to handle yourself. Good luck.

West Marine branded pumps are a direct replacement to the yellow "mayfair" pumps.

excellent feedback thanks. I can go there (West Marine) on my lunch and pick one up. PS: They come out with clockwise rotation.

OK, so the bigger question is why was the bilge pump needed? Did you take on water over the windshield or is there some other reason for the water in the bilge?

phat sack issues, and phat sack pump issues put about 15 gallons of water on the floor of my 88PS190, which eventually drained through to the bilge. Spent the day in the sun afterwards though and got the carper and floor all dried out.

So how is the wake of a PS190 with a phat sack? And did you have any room left for people and equipment?

Two 30 gallon paht sacks and a 7' pylon successfully converted my boat to a wake maker. It pains me to do it, but if I want my kids to go with me, I'm going to have to have the opition. Converting back to slalom boat is a pain though, so I think it will be a once a day transition.

My backfliiping wakeboard children said the wake was smaller, but stiffer than our old IO with the "wake of death", and they thought they got better launch off of the MC wake because of the stiffness? The wake is narrower though and they land in the flats on every jump, even after lengthening the rope.

But I was at least satisfied that if I want to convert a good slalom boat, I can.

West Marine branded pumps are a direct replacement to the yellow "mayfair" pumps.

So if my pump died, I can buy this and it should screw in and plug in directly ? Sounds too good to be true !

Has anyone done this. Please confirm

You are correct, just throw the ney cartridge in and wire it up!! Just make sure to use solder and shrink wrap or shrink wrapped butt connectors... it seems like down in the bilge, wire connections always go bad, unless proper protection is used!!!

Is it a 600, 800, or 1000 gph pump. I assume 600.

03-07-2007, 09:52 AM
The cartridge sizes are the same for all, so go with whatever size you like!! Bigger is always better!!! :D

.............................this is what they are designed for

I have an 85 like you. Quick question for you...I think that my pump is the original with the boat. It works but the auto pump is not working. Do you know should I have a float switch or is it built into this pump...I want to replace but dont know what to do yet.

The pumps we are talking about do not necessarily have a float, as I'm talking about buying the cheapy for the use of just the cartridge (motor).

The one that came on mine did have a flot, but didn't work well, I would replace it with this one if you need a new one. There is nothing to get gunked up.
