Re: 1996 150hp Evinrude problem
kit48,
Try a few simple things and go from there.
I assume that the motor will run at idle or low speed if so try pumping the fuel bulb when accelerating.
Change any filters if you haven't already including the one mounted on the fuel bracket at the front of your motor.
Check hoses, fittings, and clamps for leaks.
Let us know what you find.
