Hi, have noticed that both the exhaust tubes( between the engine and the low located muffler) have started to leak.
Have tried to tighten the rubber hoses, but the exhaust tubes of fiberglass seems to be cracked at the edges where they are connected to the rubber hoses( tigthend to hard..., or just old).
Now the question:
Is it possible to replace the tubes while the boat is in water, or does it has to be on trailer/land?

Possible yes, but foolhardy. A high risk of sinking. Do you have a trailer available? or a neighbor with a lift you can borrow?

Thanks, I wouldn't be a foolhardy, have had enough unlucky leakage this year. Sinking it would be the last I would risk!
I have a trailer, but rather steep where the ramp is, but I will take her up, thanks for advice!

You could buy a surgical Balloon Angioplasty balloon... but a very, very large one. And, Insert it into the stern end of your exhaust, then inflate it to stop the inward flow of water... while you operate on the tubes

Just kidding of course, that image came to mind for some reason.

The same thoughts have occurred to me when looking at replacing cooling hoses.

I've replaced an impeller with the boat in the water, and also cleared the tranny cooler of debri that way. But certain hoses are below the water line, so you have to be careful.

It had occurred to me to shove a nerf football or something into the exhaust outlet for your procedure. But, you'd want to have a helper back there, making sure it didn't come loose. Probably not worth the risk unless it is a real hassle to pull the boat out of the water.

Ha, my company could actually make something like this, we have the capabilities, but I don't think they'd be too happy.

3" expandable pipe plug, $8.40 at Grainger. Remove your flapper, install inside the exhaust pipe fitting through the transom and tighten. You coould completely remove the exhaust all the way from the transom to the risers and not get any water in the boat (test it for a tight water proof fit first). Of course if you can get it out of the water, it won't have to cost you anything, and it might be tough to come by in Sweden.



Has a reach of 2.8 to 3.1". They also make 4" plugs for $9.27 each. Either is rated at 40 feet of head.

You might have to rebuild the round hose connector on the mufflers. Easy job if you are handy with fiberglass. Take the muffler(s) out of the boat. Just make sure you don't get it oversize.

I had mine rot and break while I was out on the lake. I had to beach the boatto keep it from sinking. What used was a tupperwear cup from the seventies. Hammered in the exhaust tip, replaced it, and then took vice grips to pull it out the cup. It worked great.

That was on the 65 mustang.

The safest route would be to use a 4" rubber plumbing end cap on the exhaust tip. This way you can pull the entire thing off and have no worries with water intrusion or something giving way.
