Help!!! What is This?

[ICULookN]

Greetings All. I am new to the boating world and a bit adventurous I guess. I have a 2000 Seadoo Challenger and put it in the water for the first time yesterday. I had an experienced boater assisting and teaching me. I stopped at an empty dock to practice docking by myself. As I sat there I noticed my feet were getting wet. I looked down and my boat was taking on water coming from that hole under the driver seat. I opened the storage area at the back of the boat and open the access lid to the engine. There was a lot of water under the driver side of the boat in that compartment. I undocked and went back to my launch spot and called my neighbor. We pulled the boat out of the water and checked the plug which was secure and tight. We unplugged the boat and water poured out for a good 2 min...heavy constant stream. We looked over the boat and found not find a single thing. Then we saw and began to wonder what this thing was. There is a little while plastic piece up and to the right of the right engine that do not have a cover. We could not figure out what it is and what it does. Can anyone help? Should I plug it? I've tried attaching a pic...bear with me as this is my first time here.

Sorry, the pic imported sideways. The piece I'm talking about is now on the left side in the pic...sorry.

Thanks for all your help in advance.

According the the parts diagram it's part no. 59, scupper valve.

Added, sorry it just occurred to me that since you are new to boating that you might not know what a scupper valve is. It's a one way valve on the discharge of the bilge pump, its purpose is to let the water from the bilge pump out but not to let water in, it has a one way rubber flapper.

I'm guessing that I should not plug it...lol? And yes, I bought a plug for it...told you I'm new to this. What is the purpose of a scupper valve? I'm going to run to west marine and get a ball one. Sound like the right thing to possibly stop the leaking?

I have already added to the original post. It's to keep water from back flowing into the boat.

Is your bilge pump functioning?

I'm sorry I didn't read the complete posting...darn Masters!!! My neighbor and are are headed out to see if it has a bilge pump. Do they come with one? If so, my guess is that it's not working properly. Thanks for your patience. Oh, is it ok for my to plug the scupper valve and unplug it once I get the boat out of the water each time?

Yes your boat came with a bilge pump, and yes it would be O.K. to plug the scupper, however there shouldn't be a need to if the scupper is working correctly.

if it is plugged and you need to use the bilge en-route it would be a hassle, replacing the check valve is the best bet. i wonder why the outlet for the bilge is so low/ below water line? to have to rely on a obviously faulty one way valve while on the water.

I went out to the boat and followed that outlet pictured in the pic I posted. It is a hose that leads to the bilge pump. Also, I'm not sure if it is working as I don't know how to tell. (I'm very new at this...brand spank'n new!!!). The outlet is way below the water line.

I also noticed something else; only one engine had the little connector to flush it. I went to West Marine and noticed that you can not see through the piece that get connected to the boat. However, on my boat, you can see right through it. There is no check vlv. Didn't have time to put the boat in the water. Allergies are driving me crazy. I feel so lost...sigh.

If the scupper is at or near the water line, the hose from the bilge pump to the scupper needs to be routed as high in the hull as you can get it. This will keep the water from siphoning back into the boat. This is not in lieu of a working scupper but in addition.

The Scupper valve drains the foot well in the passenger compartment. The bulge pump clears the bilge. You don't want the water that may come over the nose, going down into the bilge. First... it can flood the engine, but worse... it can sink your boat. Right now... you can fill the passenger compartment, and the boat will still float. (and it's fun to do)

I've never had any luck with the ball valve. I always used a regular flap valve. Basically, like Lou said... it's a one way valve that should seal when you are sitting still, and it allows water to drain from the foot well when you are moving. Regardless the type you use... they need replaced every few years.

Here's the kind I use.
