21-EC how to remove bilge pump

[lproulx]

Can anyone tell me how to remove the bilge pump hiding under the propeller shaft in a 21-EC? I think it is some sort of bayonet twist, lift type thing, but want to be sure I can get it back once it is out. Is there enough clearance beside the propelle shaft to get it out? I am certain the factory put it in before installing the engine.

I bought a new pump for two purposes:
1) see how pump is removed
2) extra pump

Mine is a Johnson and you would never figure it out without a sample or utube. You can hardly see it when installed

I may get a new one. Mine has lots of.hours. tend to turn it on and forget about it. Model # or description for ordering? Thanks.

Replacing the bilge pump before it fails is definitely the way to go. It's a tricky job under the best of circumstances, trying to do it under pressure could be a nightmare. Like Mastercraft, I too have a spare(s). I prepped the installation by adding waterproof connectors to the existing pump wires and the spare pump(s) wires. Now, re-installation can be done pretty quickly if needed in an emergency. I also swap my pump out on a regular basis.

I added a second pump on ours forward of the engine. reason was I went to look at an R21 in Rock Hall, MD. Water was ankle deep in boat when I arrived. Checking the situation revealed that the pump was wired to the start battery and the battery had went dead from pumping. Also, someone had shut off the breaker for shore power. So, with this experience, I always make sure the main pump is on the house battery as I have seen a few boats with the pump connected to the start battery. My second pump I wired to the AC battery bank, so basically I had 3 batteries for the pump, plus I could always start the engine for power, if needed.

I thought I had posted this before but couldn't find it so here it is,,,again maybe.

To remove the cartridge from the pump you need to pry the little black tab near the top out a bit. You can pry it out and push it down. It only moves down a bit, sometimes it stays, sometimes it slips back up and back in its slot. In any case it need to be out to release the cartridge. After the tab is out of the slot just rotate the cartridge counter clockwise and lift it out.

If you want to remove the base as well, mine is held down by a couple of screws, one in an outside tab and one in the centre of the base which of course you can only see and remove when the cartridge is out.

Not a lot of room below the shaft but on mine it does come out. I have replaced mine a couple of times.

The one in the photos is just a spare that I made up with small clamps that I could quickly swap in and connect directly to the battery should the need arise. I also have a hose Tee'd into the raw water suction line. Should the need arise I can drop the hose in the bilge, throttle the sea cock and suck out the bilge. Hopefully never have to use it but it's there as an option.

It's a Johnson 750 GPH pump.
