1989 268DA Macerator

[jcoyrochny]

Just purchased this beautiful Sundancer, I have a Jabsco Macerator pump in the head and there is a key switch that I cannot get any of the keys that came with the boat to work the switch. I have been digging at this for almost a month and cannot get an answer from Jabsco in regards to how I could change this switch maybe to a toggle switch or something that will let me use the mecerator. Any help out there?????

You could get a keyed switch from an auto parts store. It works just like the start key on the boat. My pump powers up in the start position. It doesn't do anything in the run position, Thats how it is wired. I assume you could also use a switch like for your trim tabs, one you would have to hold in the on position in order form the pump to work. You don't want someone leaving the pump on and running it dry. You should probably use something that is rated at 25 amps. If I remember thats what the fuse for the pump circut is.

I have also been working on mine. I have had my switch apart. Steve is correct in that it is like an ignition switch. Off-On-Start (momentary). The pump is only designed to run for short period. I also just replaced my pump and I have an electrical issue.

I am going to find a momentary switch, like a horn push button. I am hoping this will fix my low voltage at the pump. If not I get to run a new wire.

Tom;
Here is a link to the Jabsco Macerator Technical Instructions, you may want to look there for what you need or will need for wiring. I just might go for a momentary switch as you suggested. If it holds a 20 amp fuse, I guess a 25 amp switch will not do any harm.

I have the same key-operated switch in my head - but luckily the PO left it dangling in the switch. I've never used it, although I have been 3 miles out a few times. I'm afraid to even touch the seacock. Anyway, whenever the vessel safety check guys come on board to look around and give me a sticker, they want to know if my Y-valve is locked or zip-tied. I say no but tell them about the key that operates the macerator/overboard discharge pump. That satisfies them.

i have a 1996 sundancer 290 and my macerator has a pushbutton momentary switch. i understand it pulls sea water into the toilet and i have to hold it in for maybe 7 or 8 seconds to get a "flush". theres no key and its a rubberised spring-loaded switch which would seem a better option.

dont know if that helps...
