wash-down & 2nd bat in port lazarette?

[breausaw]

I'm considering placing my house battery in the Port lazarette along with a wash-down pump and hose; think there’s enough room.

A Perko duel battery switch would be placed in the starboard lazarette with the cranking battery; I want to keep the system as simple as possible-everything tucked away/dry and out of the way.
So wondering if this is a good idea or do I need to re-think the process. :roll:

This second battery would also be dedicated for wash-down.

:smile Dealer installed both batteries and switch in the starboard lazarette which works out fine except it's a little more of a chore getting them out. My C22 had a factory installed shelf for the batteries and it has plenty of venting which is needed for charging. My port lazarette is "water tight" and it's set up as a live well. My water pump for the wash down is located under the stove and the connections for hose is in the starboard gunnel. My was down is taken from the fresh water tank, (we're salt water boaters). At the end of each outing, I hook up the wash down to the motor and drain the watertank thru the motor, thus always keep fresh water in my tank. Just to be sure, I always put a few ounces of bleach when filling the water tank. :smiled

If I’m able to get both batteries in the starboard side that’d be great, but don’t won’t to draw from fresh water for wash down.
Think both lazarettes are water tight on top, at least mine are. I’d guess adequate venting is achieved by having them open on the underside.

The older 22's did not have "air tight" lazarette compartments, but they were splash proof.

I wonder why you want to dedicate a "house" battery to wash down? Generally the house battery is used for the stove, lights, electronics and any pumps. This way, the engine start battery can not be run down accidently, plus the electronics are spared the voltage drop and surges which occur with engine start up. The batteries are connected with Voltage Sensative relalys (VSR) or switches. This is a very time proven method and works well.

Sorry, what I ment is along with being dedicated as a house battery it would also have a direct line to the wash down pump. Or I could just run a line over to the Perko switch.
Hay, I'm new at this stuff

I've got two group 24 house batteries in my port lazarette so I'm sure there's plenty of room. I don't think I'd put the pump in there though, I'd prefer it under the sink plenty of room there and easy access to water supply and power.

If I can fit another battery in my starboard laz where my one cranking battery is now, I still think the port laz is a good place for a wash down; I’d never use it for a live bait tank-not for the kind of fishing I’d do in Alaska waters.
You’re the second fellow who has placed their wash down under the sink, seems like an unlikely place if you need that space for cruising supplies and provisions. I guess if you tie into the fresh water that’s a good place; I’d be putting a sea cock next to the drain plug for seawater.
The boat will be wash down with fresh water after every use.

In Fishtales, I had the starter battery and switch in the starboard lazarette and two house batteries in the port lazarette. I removed the drain plug from the bottom of the port lazarette and had an additional covered opening to the engine well.
Damn-- I had that boat set up nice :evil:
I will do the same with the new boat.

edit-- My raw water wash down was the same as Fran Sea's- located in the starboard gunnel

Jay, Sorry I miss understood the use of the second battery. Yes, you can put a fuse, and a switch in the wiring from the second (house) battery to the wash down pump. Many people put the wash down pump below the water line, to make priming easier. The diaphragm type of pumps do not have the problems with running dry, which the vane type of pump has, so you might be able to place the pump in the physical location. But since you want a mesh filter before the pump, and there will be water connections, I would feel better having the pump in the bilge area, and the battery in a dry area. Also when putting a thru hull in the transom, rember two things: first you need to be sure that any wood or foam in the transom core next to the thru hull, is removed and replaced with epoxy/filler. Second that when the boat is on a plane, you may not be able to pull in water. (this may not be important if you will only use the washdown when at low speeds or at rest.) This is why the usual thru hull for washdowns is in the bottom of the hull (which also has some disadvantages with a trailered boat)

:smiled All electrical connections on "The Fran Sea" are made thru the perko battery switch with the EXCEPTION of the stove which needs a cool down period to prevent fires and thus you can't acidentially shut it off when it's still very hot :cry

Thanks for all the feed back; I value everyone’s knowledge and experience.

Here’s a thought, has anyone ever come up with a plug for the transom that would double as a seawater pickup for a wash down pump, or would this be stepping into the danger zone?
Perhaps someone makes one of these doohickeys? One could modify a seacock so it can be secured from outside the transom with a locknut preventing it from leaking?
I know the dang robber plug is not always leak proof when not adjusted properly or has been installed improperly.
If there’s a way to get around drilling another hole in the transom it’s a positive thing.

Allthough it could be done, I would think that combining a drain plug and water pickup is not a good idea. I always leave the plug out of my boat when it is on the trailer, and this would mean moving the tubing which connects to the washdown pump each time. You also want to close all thru hulls when you leave the boat in the water.
