Re: 1988 Johnson 110 hp starts out of water but not in water.
I had the exact same problem with my 1984 evinrude 150.I tried everything you are trying and finally gave up and put it in the shop.They checked the compression.It was great.They cleaned the carbs and replaced the plugs.They even replaced a bad powerpack but it still had the same problem.Finally they replaced the stator and it works fine now.It all cost me about$1000.
