  • 40hp Merc Big Foot EFI loss of power

    I have a Model 40 ELPT 48. 40 hp Big Foot on a 16 foot pantoon. The engine starts perfect, but seems to have a bit of a miss fire. When going to full throttle the engine will only go up to about 3500rpm and no higher. After about 40 minutes of running it will just die. It will start, but when trying to accelerate, there is very little power, and the engine will go only to about 2000 rpm and then back to idle. Gas is fresh and plugs are new. Please help.

    Sound like could be going into limp mode. You should have the computer diagnosed.
