    New Exhaust Hose split-gctid803835

    Interesting thing happened on our first cruise of the season this weekend. Doing some work on the boat and I heard the sound of trickling water. Opened the engine hatch to find water dripping rapidly from the port exhaust hose that runs from the riser to the water muffler. I had replaced my risers last season and used brand new 5" hoses. These are the hoses with the SS wire inside. It appears to have cracked/split at one of the seams. There is a very very slight bend to the hose but at the location it split there should not have been any pressure. These hoses are less than 12 months old and were exactly the same as the prior units that lasted 16 years. I was able to get hold of some rubber pipe tape that I used to repair the leak and it held for our trip home.

    Any idea why the hose would have split so soon? Should I take it back and ask to have it replaced? Should I be using exhaust hose that doesn't have the reinforced wire inside?

    If you didn't use made for exhaust hose, get that stuff replaced like yesterday. If it is, indeed, exhaust hose, yes, I would take it back and still buy something different at a higher grade if there is any. It could be that there was just a bad spot in the hose, congrats on catching it.

      The dia might be right was the length ?

      Did you clamp the hose to the pipe in the correct position ?

        I'm not following you here, what do you mean by seams? There shouldn't be any seams in the hose.

          Sorry, may not be using the right description. There are the ridges where the stainless wire runs and then little valleys. The hose split in one of the valleys between two of the wire ridges. It's exactly half way along the length of the hose between the riser and the muffler. Yes, the hose is proper marine exhaust stuff -- same stuff as what came out of the boat.

            Yes, length and diameter were the same as what I had removed. I used the old pipe and cut the new to length. It was clamped on the muffler and riser ends with some extra room for expansion.

            Has me wondering if the wire reinforced hose is the correct product for this application. Length of the hose is roughly 30" and the split happened about half way along in one of the valleys.

              Wow! I'm not the only one who has things screw up by doing everything correctly. Sounds like the hose is defective and there's no way to predict that.

                Will be carrying around a roll of rubber pipe repair tape from now on. Got us home safe and dry.

                  Terry,

                  The hose you have appears to be Trident #252. It's designed for long runs with substantial bends. It should not have split in your application, but maybe it would be better to use non-corrugated exhaust hose. Better yet, a silicone hose, they are more expensive, but last much longer.
