Question Another Day on the Lake, Another Problem Discoverd

2000 MC PS 205V - Seems like this may be related to my post yesterday - where the ballast bag kept emptying after filling. Didn't use the ballast today, but when we were putting the boat up, my son was taking out the center plug and said "Hey Dad, there's a broken hose down here." It was getting late and light was not the best, but sure enough one of the bilge pump hoses was hanging loose. Actually the hose was OK, but the plastic nipple on the bilge pump had broken off clean, so only a short stub was left on the pump, the rest clamped inside the hose.

Seems like there are two bilge pumps near the centerline. Both pumps are cylinder shaped, yellow sides, black tops. The broken nipple is the top nipple on the pump on the drivers side - It faces toward the stern, but the hose does a 180 and then heads toward the bow. The passanger side pump looks identical, but seems to be connected to some kind of switch with the word VENT on the switch top plastic cover.

Anyone know what kind of bilge pump I need to buy or how I can find out? How difficult is it to replace the broken pump? Any special tips or "watchouts" - Or should I just let the dealer do it? Thanks for any help.

I may not be reading this correctly....
but I'm thinking you broke off a "barbed fitting" like this:


or is the "wet end" of that pump molded all in one?

Yes, the barbed fitting broke off, but it is does not have threads like the picture you posted, it appeared to be one molded piece of the pump.

I once had a screen filter/ barb piece break off on my travel trailer's fresh water pump... went and searched google and found the wet end head that fit that pump. Same thing on my swimming pool's pump

that may be an option, or replace the whole pump and repair the broken one as a spare.

I've replaced a lot of bilge pumps on various boats. I'm new to Mastercraft, but I assume the concepts are similar, especially after taking a close look at the forward bilge pump on my new Maristar. Compared to my last bilge pump replacement in my Century I/O, replacing the one in my Maristar would be a comparitive chip shot (due primarily to accessibility).

You need to select the bilge pump based on size of the hose it will connect to (needs same size barb as previous pump), and a built-in switch. Within that range, get the largest capacity pump you can find IMHO. If you go to almost any boat store, you will see racks and racks of bilge pumps. Pull out the old one and screw down the new one in the same location. There will be three wires going from the boat to the pump, so that you can switch it on manually, but will also switch on automatically via its internal float switch.

Many bilge pumps have a cage that is screwed down to secure to the hull, then the actual pump just clips onto the cage. Theoretically, you could just unclip your pump from the existing cage, and clip in a new one of the same model. In reality, you may find it difficult to find that same model pump, hence the whole unit, cage and pump, needs to be replaced.

The only "watchout" I can think of is to make sure you get it wired correctly. Almost all of these automatic pumps have a little trip lever on the outside so that you can trip the float manually to test its automatic fucntion. When you're done, make sure that you can activate the pump manually from the dash switch, and that tripping the float lever on the pump also turns it on.
