Tommy that works for me has a 1995 Mercury 40 hp outboard. It's the 4 cyl 2 carb engine. The issue is at full throttle it acts like vehichle that hit the rev limiter (cuts out) If you name it, it's been replaced. Two shops have had it and no luck. The guy in Elloree looked at it and said it runs fine.

Not looking for ideas, but more so of any old school Mercury techs out there.
