Just to get it out of the way, we use our boat a lot in the Bahamas, where there are very few pump outs. We always pump out when we are under way, usually offshore unless we have no other choice. We never pump out in anchorages.
My macerator pump is located next to its through hull under the stairs leading into the forward cabin. Its breaker is located on the panel next to the galley. In order to pump out the tank I have to lift the steps, open the seacock, lower the steps, then go up to the panel and turn on the pump. Same thing in reverse to turn it off. I don't like to let the pump run with seacock closed.
It's really a two person job, but I'm often alone or the other person is running the boat, not fiddling with a pump out.
So I'd like to put a switch next to the pump, mounted on either a stringer or a bulkhead. I don't want to just splice a switch into the wire without mounting it. I'm having trouble finding a single switch that can be bulkhead mounted. Plenty of switch panels, but I only need a single switch.
Though it is sort of overkill and expensive for a single switch, I'm considering a small battery switch like this:
The locking key is an added benefit from a legal standpoint but I don't have to have the key as I can zip tie the seacock handle closed.
Any other ideas?
