Salt water in my engine
Salt water in my engine. 1972 Pearson 30 , inboard universal atomic 4 gas engine. Went out in a high steep sea with engine running , turned off engine, sailed in 3 foot chop , engine refused to start; sailed back in to harbor, anchored , pulled plugs, found salt water on plug electrodes. Ran engine with plugs out , replaced fouled plugs with new, engine worked. History; blown gasket two years back (lots of salt water in engine) led to new exhaust system; exhaust exits boat from transom about 3 inches above water line. Raw(salt) water cooling. Exhaust gas exits manifold, rises one foot, levels off, then descends one foot into round black device (which I think is a muffler ( I write to prepare myself for meeting with the guy who did the work 2 years ago)) as exhaust pipe descends it is met by smaller line from the manifold which I assume is for water injection into the exhaust gases. Called guy who did the work ; he asked me about following seas, and suggested a flap over the exit on the transom. Looking at the system today it seems very unlikely that water could have found it's way from the transom through 5 feet of hose ,up and through the muffler , and up another foot , especially with the engine running . I sailed her a full year after his work, though not in anything quite so pounding .could water have gone all this way ? |

Just a thought, did you have a siphon break in the exhaust? Hot engine
cools and draws water in... Cheers J Bard wrote: Salt water in my engine. 1972 Pearson 30 , inboard universal atomic 4 gas engine.

Syphon break..about AU$100 in most chandlers here in Oz. I wonder if Doug knows anything about marine engine installation in sailboats? Cheers |

oxxy, you do NOT put an anti-siphon valve in a wet exhaust. A wet exhaust
ALWAYS has gases in it, so there is not need for such a valve. In addition, the exhaust outlet is above the waterline, so even if there were no gases in the exhaust there STILL would be no need for such a valve.
