Default pumps in bilge area may-craft skiff purpose??


Can you please tell me what the purpose of these two pumps are? The transom is to the left and the hose on the top is intake hose for the baitwell. Should the petcock on the pump be on or off? Thank you.

Where do the hoses lead to after they leave the pumps? That'll be a good clue as to their purpose. Leave the seacocks closed for now.

A pretty good guess......the flatter square type one is your bilge pump. The rounder one is for your live well....

in all seriousness you should have someone go over the boat with you ASAP. A local surveyor can show you the ropes if you don’t have a friend or dockmate to help you.

The hose goes under the floor toward the front end

Thank you. That is helpful. I have never had a baitwell before and the manufacturer has provided no assistance.

The Tsunami pump supplies water to your livewell/baitwell. It probably has a high speed pickup on the hull so leaving that valve shut will prevent the livewell/baitwell from filling up while running.
The Sahara pump is an automatic bilge pump that will pump water out if it reaches a certain level.
My question is where does the other hose go that has the valve closed?
I, also, would suggest getting someone more knowledgeable to go over the boat with you to help you better understand it's systems and their operation....

I'll guess that the larger hose on top is the drain for the bait well. Not sure why it would need a valve.

You need to become familiar with your boat, understand all her functions before splashing her in the drink.

The two pumps you inquired about are fundamental to your safety and keeping your boat floating not sinking.

If either of those thru hulls break, you're in big trouble.

One pump is your livewell feed.

One pump is your bilge pump.

Start reading all you can about boats.

This is the best place to start.


That large hose on top with the inline valve is most likely your livewell drain. Keep it closed unless you are using your livewell. You have a seacock ( as you should) on your livewell feed: that should remain closed as well : it's your wall between the water and your boat.

Thank you for your help. I truly appreciate it.

I am pretty sure it is the intake line for the baitwell.

Normally the larger hose would not be the intake for the baitwell (livewell). As mentioned the baitwell pump should be the T-800. Your baitwell has to have a drain which I suspect is the larger line. Fill up the baitwell and check what happens with valve open and closed.

The larger line that has the valve is your live well drain. It has a valve because it is below the water line. If the line were to split or get a hole in it, it would fill up the bilge with water coming from outside the boat if that valve was not in place.

You've been on this forum for fifteen years.. you've got the ability to take and post pics of the issue in question but you can't trace a hose?

Come on... admit it..you pretty much lead with your jaw on that one....

Default should be close when not on board and in water

Even if valve is in place if the hose failed it would still sink your boat if now closed... I overnighted on a 40'Viking and when I got out of the bunk in the morning I was standing on wet carpet... a below water line fitting had failed and had been leaking water all night ... managed to cork the intake and pump the boat out and made the repairs... luckily, we were at the dock when it happened... Something that small can kill you..

for the same reason any underwater through hull has one, to stop the flow of water if the hose lets go.
