Does anyone know what that plug is for? I lost the cap in the drink. It's about an inch and has 2 holes in it with a screw top... Just under the catbird seat. I can post a pic if necessary. Thanks!

Also when I got to the boat on Friday the marine head bowl was completely full of brown waste water. Online says to replace joker valve, anyone else have the same luck?

Apologies if this has already been discussed. iPad doesn't search this forum properly.

The plug may be a 12 volt outlet, use a voltmeter and check the holes for voltage.

If you have a marine head with a holding tank it may be full and the choker valve may be leaking causing the head to back up. If that's the case I'd empty the holding tank then try flushing the head and see if it stays clean. After emptying the holding tank and the bowl remains empty I'd replace the choker valve.

It's a vent, not a plug, for your onboard propane system that fuels the galley stove.

Will, that cap sounds like the same one my solar panel is connected to, and if so, it wasn't a factory installed piece (or at least I don't think so). [url="http://www.sea-dog.com/groups/1992-polarized-electrical-connector"]This isn't exactly the same one as mine[/url], but should give you the idea. Mine has a screw down cap, but the connector itself doesn't screw in.

I can't comment on the joker valve, but it sounds unpleasant. You might try asking your question on [url="http://forums.sbo.sailboatowners.com/forumdisplay.php?f=31"]Peggy Hall's Head Mistress[/url] on SailboatOwners.com. She was very helpful when we were looking to replace our leaking porti-potty a while back.

If you look on the left side of the page at the bottom of the various links, there is a Google Search function that'll probably work better with your iPad than the standard forum search feature.

It sounds like a plug for a Perko pole light. Why that would be on a 250 I couldn't guess but I had one on my old Beachcomber cat-rigged ketch.

I think some outboards connect to the battery that way. If your outboard does not, it might be left over from a prior outboard.

Another possibility might be a connection for a RAM mic for a VHF radio, though I'm not sure if any of them use only two wires. A more likely possibility might be a weatherproof connection for a monitor speaker or PA speaker for the radio.

Ah thanks! I climbed into the aft battery compartment and about a foot of cable is just hanging there snipped off from this connection. Here is an outside pic for reference. I appreciate the help!

That looks like one of the Sea Dog connectors I linked to above. Wonder what it used to be connected to?

You're right David. Who knows what it was used for but I guess it saves me from drilling a hole if I need to put anything 12v back there in the future! :)

I'm betting it was a connector for the alternator cable from the outboard, installed by a PO. Probably cut the wires when he/she quit using it. Could also have been used for a VHF speaker connection. Contact Perko and see if you can get a cap for it, or tape it off the keep rain water out of the leads.

Not a great location, as the plug blocks visibility of the stern light.
