salt water in engine - AGAIN ! Head Gasket ????
Universial Atomic 4 (inboard , salt water cooled) - 2 years ago I found salt water in 2 cylinders and my mechanic suggested and then did a head gasket ; she ran fine for 40 to 60 hours of use, and then - more water in the aft 2 cylinders nearest the exhaust ; I was in rough seas - and there is a possibility water sloshed it's way back up - I did some work on the system to make this less likely, and used the engine for 10 more hours ; worked fine - and then it happened again, in seas much less rough but still rougher than the prior 10 hours - so my question is , can a head gasket fail randomly ? Can it hold most of the time and then give out , and then hold again, or is this a matter of water working it's way back up through the exhaust ? |

You are probably getting water coming in from the exhaust.
It happened on a boat I taught on when in big following seas. A flapper valve on the exhaust would help. I have a gate valve on mine, and I'm considering putting a ball valve on it to make it easy to secure. Barret Bonden wrote in message link.net...

You just need to be sure to open it.
I would have a big yellow flag I'd tie around the wheel as a reminder when it was closed, or something of that nature as a reminder to open it again. I think it is a smart way to avoid loosing your engine or boat. In fact a boat I sailed in charter in the Caribbean was lost on it's return north because the engine failed. What were they using it for? There was plenty of wind? The crew were a bunch of screw ups. They didn't have all the right safety gear, tried to rely on the engine in rough seas, and were helicoptered off near Cape Hatteras. Why? Because they were sea-sick! All they needed was to make a drogue with the three corners of the sail tied together or drag some line, or something. The boat wound up on the beach wrecked. It didn't sink, which will tell you what losers the crew were. Every time I read a story like this, I wish the helicopter would drop me off when they picked up the crew. I'd like to have a free salvage boat. Capt.

How high is the riser in the exhaust system? Here a friends trawler did the same thing, he anchored and had stern seas wash over a 1 foot tall riser in his exhaust. Got water on top the pistion. When he went to start the engine he bent a connecting rod, and fractured a liner. If you havent bent a rod yet you better get it fixed, you could throw a rod thru the block. But since its a dangerious gasoline engine it might be a blessing in disquise. Start looking for a safe diesel. Or put in a riser thats tall enough to keep water from backing into your engine. Flapper valves are a freekin joke and a waste of money IMO. Joe |
