Was out for short cruise yesterday when we went in, noticed good amount water in bilge:( Traced it to small half inch slit in the 4 inch dia exhaust hose. Hose is several feet long from engine to muffler.

Has anyone had any success with Silicone Self Fusing Tape as a temporary repair? I'd like to get thru the season without replacing hose.
 
what could cause it to fail? Very strange. Does it look burnt???

You need to find the cause before trying some temporary fix.

?? Is hose electric ??
 
CO gasses are what would make me replace that hose! Is there a reason for the corrugated exhaust hose like a sharp bend at the transom? If not I'd replace both runs with NON-Corrugated 4" Trident exhaust hose. Looks to have easy access, double clamp both ends with quality clamps and remove the possibility of an issue.
 
What you suggest seems more appropriate for a get-home-emergency-repair than a "rest of the season" fix. Since that is apparently not the case and the question is referring to a situation that could poison the POB's with CO or sink the boat with RW water, I would advise doing what I might imagine you would consider as the "right thing" and haul the boat and replace the exhaust hose. Possibly with higher temp blue silicone exhaust hose. Also consider if one hose is dangerous now. the other may be soon. So perhaps replace both?
 
Carver 360---- inboards, right? If exhausts are above the water line, why would he need to haul the boat to replace exhaust hoses to muffler?
 
I think the exhaust is right at the waterline. Bounces under and over with the waves. The flippers keep some water out but not all.

CO gas entering the bilge is a safety risk. Replace the hose or stop using the boat.

Please don't mess with CO gasses, it's a silent killer.

This is a boating education site, glad everyone is giving the same advice - REPLACE damaged hose, don't screw around, it could be deadly.
 
Indeed if they are gassers it is very dangerous. It is very rare to see an exhaust hose just split. Hard to imagine enough back pressure in the muffler to cause bursting but IMO the hose needs to come off and the cause found.
 
"Traced it to small half inch slit in the 4 inch dia exhaust hose"

Can't really see well in the picture but if it is slit you might want to ask yourself who else has been in the bilge and perhaps doping work.

"The flippers keep some water out but not all."

Temporarily you can replace the flapper with a complete dead end rubber cover available at places like Home depot in various sizes. This will allow you to replace the hose with out pulling the boat.

Hope this helps

I saw one split on a 40ft kinship. Sunk at the dock.

Yes I've seen this done and is a good much simpler solution, Smitty. Thumbs up to you.

Similarly , when I replace riser/elbows on my gassers, in order to safeguard the engine end of the exhaust hoses in case they were to fall below the water line, I insert PVC pipe caps in the hose and hose clamp. (My exhaust outlets are 1/2 under the W/L.)
 
The fact that he doesn't have to pull the boat to do the repair makes things a lot easier. Fix it right, now.
