My 150hp v6 2-stroke outboard is doing the same thing. I've replaced everything from fuel tank to injector, no change. Did you find the problem with your mercury. Mine is a 2000 saltwater series mercury. Help would be greatly appreciated.

Check your neutral safety switch by un plugging it and see if it has power at full throttle.
