I think I really screwed up. This winter I went to the marina one day to start up my Universal M-25 to charge the batteries (no shore power). I picked a particularly cold day and was unsuccessful. Here is the boneheaded part. I failed to drain the waterlift muffler. When I went to the boat this weekend, I had copious amount of oil in the bilge and raw water in the oil pan. It appears that the water backed into the engine from the muffler and displaced the oil. I have since cleaned the bilge and replaced the oil. I was going to run the engine for a few minutes and then againchange the oil. The problem is that the engine won''t turn over. I don''t believe it is a battery or starter issue. I feels like the engine is locked up. BIG PROBLEM. Does anyone know if the engine can be salvaged, If so, what kind of money are we talking about? If not, any idea what a new M-25 or comparable costs?
