"I have a 89' 100hp Merc, Just had trim tilt motor replaced also airbox gasket due to a leak.( Done by Service Co.) I then replaced the spark plugs. Ever since it is really hard to start in the water to the point of flooding. Never had this issue prior. Starts fine using flush cups. It does eventually start and with a bit of smoke and a few revs it runs fine. But then I have to use the choke to restart when warm. Could this be a faulty plug? Also with the gasket replaced would this effect previous tuning from when the gasket was leaking?"
