Wash down pump replacement

[HandsFree]

I need to replace the wash down pump on my 1997 3100. Thinking I can do it with out hauling it out by shutting off the sea cock right? Also is that pump 12v or 24v? Anyone replace theirs with a Whale wash down pump?  Thanks for your input.

No need to haul out, just close the sea-cock.

That boat should have all 12 volt DC equipment.
