Some of you might remember an article I posted early April following our discovery of the Frozen Yanmar in a friend of mine Hughes 38, winterized in Montreal.We do not have all the answers yet (where the water came from still remains a mystery) but I am happy to report the following. Last week was warm in our area and all the ice melted in the Hughes bilge where the motor is located. Following the review of all opinions received, we did the following:Cleaned the exterior of the motor, especially around the in injector area. Check the oil and found no trace of water in the oil. Remove the air filter and remove all the water accumulated in the air intake with absorbent paper. Replace filter element. Remove the fuel lines and remove the 3 injectors, cleaned and oiled. Add the equivalent of Marvel Mystery oil in each cylinder. We used an other product cause MMO could not be found here. Waited for 20 minutes. Slowly turn the crank using the alternator strap, until my friend remembered he had a crank handle for this usage. In the beginning, the crank was difficult to turn. After 10 minutes it was easy. We did all of this very carefully to save all internal components. Water/Oil was coming out of the injector holes. When we noticed that all things were turning freely, we put a rag over the injector holes turn the battery ON and I ask my friend to push the starter once with the engine stop pulled. What I did not think of when I asked my friend to do this is that the compression of the pistons is much stronger when pushed from the starter than by our manual crank turning. The rag flew off and we had droplets of oil and water on the ceiling. Not too bad, at least we knew the starter was OK. We continued to use the starter to make sure everything was working free. Cleaned everything one last time. Re-assembled the injectors and fuel lines and bleed the fuel system. We then removed the compression with the 3 levers and made the motor turn for 3 stints of 10 seconds. No problem.Put the compression levers back in place, push back the engine stop and were ready for the start. Some of you might not believe this, I am the first to be surprised, but the engine started with the first push of the starter button. We did let the motor run for about 15 seconds. Re-started and everything was running a smoothly as if nothing ever happened. Remember this engine was flooded and frozen solid for a few months… We just won a battle, not the war but at least we might have saved the motor! We will now change the oil at 0.5, 1, 5 and 10 hours to monitor everything. We might also use a test kit to have the oil tested. We will remove the starter and Alternator for complete cleaning. Both are working fine now, the alternator is charging the batteries OK.This site has been more than helpful once again. I am not a mechanic, but was able with a methodic approach to analyze answers and follow the most plausible way to go. Special thanks to RichH from Worton Creek, MD. Ken from Edmonton and all the other contributors. We now think the boat will be in the water for our summer cruise on Lake Champlain.
