Source of water

are the pulsation dampeners hollow?

Mark,
Those are the ones you need to use since as mentioned the originals aren't made anymore. The two mounting holes need to be elongated slightly to match the old holes. I would also use the 3rd hole in the new units. Don't forget the 5200!!!

Yes, the old tubing is usually under the foam. Just abandon it.

Cannot help with the new pitots but the tubing on my 87 runs about 4" inside of the transom and then connects to the bottom of the dampeners previously mentioned . The tubing then runs off the top of the dampeners to the speedos.

So one Pitot is definitely broken, which means they both will be replaced. But who sells ones like the OEM? The couple of places on the web I looked at seem to be different looking than what is on there now. Does the tubing make a home run to the back of the speedo or are there connections in between?

Well while swimming today I reached up and touched the Port side tubing where it attaches to the pttot at the back of the boat and it broke off in my hands. And this was the side that actually worked. So now I have no speedo's. Do the pitot's ever go bad or just the tubing? Not sure how it should have looked before the tubing came off, but I assume there was a nipple that stuck out and the tubing attached to it with the nut. I just need to know what all I need to buy to replace all the old crap so it is 100% new. I am not even sure if the part at the back of the boat is actually the pitot, but I figure it must be. Looks like a dagger sticking into the water.

Does the tubing ever rot?

The speedo pitot tubing and pulsation dampners were mentioned earlier in the thread. Check them out. You'll need to be underway to do this. Any leak and you'll get a fair amount of water.

Holes not sealed around speedo tubing where it exits for the pitot tubes. Cracked speedo lines or dampeners. Do your speedos work? might be a clue. You will probably have to pull the tank to find it and fix it.

I have noticed that more ofter than usual the bilge goes on. so I did empty all the water out, dryed up the bildge area and the looked for water. i found it comming up just forward of the ski pylon under the deck . it was not comming in fast

so does that mean this is not the source of the leak?

Also I tried to upload a picture of where i think the water is coming from but it did not work. how do i upload it

The fins are through bolted and should be pretty easy to seal up using Pete's described method above. 5200 is amazing stuff. I applied it to the top of the fin that makes contact with the hull and even put some topside under the washers just for good measure and because the tube seems to last forever. Good luck!

Hi All


I have a 95SN its my second summer as owner.

I also have water coming from an unidentified location . I followed the above threads ( great conversation) and have isolated it to somewhere from the 3 fins. The water seems to come up in the area in front of the ski rope pylon under the deck. See the picture.   I took the boat out of the water and checked the fins looks like it had been resealed before. what is the best procedure for this repair. If I unscrew the fins will I be able to screw them back easily? does the screw go into a receptacle or is it directly into the fiberglass. any advise would help. thanks

One last shot. Mine Came in the shaft log and flowed out the stringer. Uphill in my book. You forgot to factor in pressure.

Sorry I Kind of hijacked this thread but my intended points were these.

1. I want a long list possible problems to look for, first so I do not go to the lake and find out it is not the shaft log and then return home for the next post only to return to the lake again to look at the rudder/through hull fittings ect. And also the more that is discussed the more I learn. I am not an idustry expert but hope to someday be a wise poobah with increased experience and the help of this site.

2.This is a discussion forum, why discourage discussion? If it offends you dont read it. Accurate advice is seldom backed up with reasoning, leaving little to work with when contemplating future situations , but bad advice leads to argeuing and explanations of reasoning and far greater learning potential.

3. I am just a user of this site and not in a position to judge others fitness to contribute. I can challange their input but not judge their worthiness to post. If I could make that judgment I would ban arrogent / discouraging members who put the poo in poobah. Good teachers have knowlege AND the ability to foster others to want to listen and learn.

4. The most common reason for water in the bilge is forgeting to put the plug in .

5. I can find the source of most water leaks in minutes. It is almost always the lake. Can I keep my boat?

Again water flows down hill not up hill so it really not that hard to trace it back to the source and use common scense and logic to solve the problem and find the leak.

Mine flowed from the shaftlog to the stringer when in the water. I believe that is uphill I believe you forgotr to factor in pressure.
