Drowned Merc 25 won't start
I lost my 1987 , 25 HP merc overboard into a freshwater lake. It was on the bottom for a week before recovered and immediately did the recommended dry out procedure. The motor was running about 1/2 throttle when it went in. I have cleaned the carb, dried out the electrical connections, put alcohol in the cylinders- and of course oil. Now , when I pull the starter rope, I get a "pow" like a backfire on the first or second pull. Exhaust smoke come out, but it really doesn't sound like it is trying to start. Then, I can pull it 50 more times and nothing happens. I can wait a day and try to start it again- and "pow" on first or second pull and then nothing until the next day? Compression seems to be good., but I have not had a gauge on it.
Any suggestions on what to try next?
