My P-60 is configured with an unside down U-shaped flange attached to the exhaust port from the engine. Near the top of the upside down U is a small hose which injects seawater into the exhaust. Right at the point where the seawater is injected there is a threaded joint which was attached to what appears to have been a simple cast iron threaded connector which was male on both ends. One end threaded into the bottom of the upside down U and the other end threaded to a 90 degree elbow joint which was then attached to exhaust hose which runs to the muffler. The elbow joint is very corroded and the threads which went in to the upside down U flange are totally corroded to the point that the assembly fell out of the upside down U flange. I cannot seem to find any documentation on the type of threads and size for that particular fitting. The old one is so corroded that it is very difficult to identify it that way either. Anyone have any idea what the thread type and size should be for the part that should thread in to the bottom of the upside down U for the P-60 exhaust? I am not 100% confident that I will even be able to thread it because of all the corrosion but I am hoping that it will work out. Always open to alternative ideas if there is a better / easier / cheaper way to get this all connected back again so I can run the engine once again. Thanks as always! |

Worked it out. Wound up taking a short piece of 2" exhaust hose and fitting it over the outside of the lip on the upside down u-shaped pipe then cinching it down with a hose clamp. I put a 90 degree elbow on the other end of the 2" exhaust hose and again clamped with hose clamp. The elbow had a threaded nipple which fit perfectly inside a 1.5" exhaust hose which runs to the muffler nipple and fits perfectly to the muffler. Ran the engine for a while today and it seems to be working fine though I intend to keep an eye on it for a while to ensure that the heat at the initial joint is not too much for the exhaust hose over time. Hope this helps someone else in need. One interesting side benefit... apparently the exhaust system must have been leaking for quite some time before I realized it because the engine is running much quieter now :=) |
