9.9 mercury 1990 choke

Post by water bouy » 02 Aug 2016, 18:25

This motor seemed to run okay in the barrel of water the day I bought the boat but the choke had to stay pulled out for 3 or 5 minutes, then it hit a sweet spot and ran fine. If pushed in too soon it would shut down. He also said gas would leak out after several days when not in use. Sound like rubber needs to be replaced somewhere? I may trade this motor for a 20 hp Merc and want to know what to tell the guy the problem may be. His is a tiller made about 1974.
