I have a 1983 mercury 90 hp two stroke. on a 17' 8" fiberglass bow rider. (SeaSprite) I bought this boat and motor new. All most from day one it would stall if I "Hit It" while trying to get a skier up out of the water. But if I would advance the throttle slowly to full throttle the motor would accelerate fine. The motor works perfectly except for this problem when water skiing. I spent a fair amount of money the first few years I had the boat trying to solve this problem with my dealer. I even wrote a letter to mercury explaining my problem. To there credit they sent a factory tec. to my dealer and together they tried to solve the problem. The fuel pump was serviced and modules replaced at no coast to me. Over the years I have had another module and the magneto replaced because of different problems always by a dealer. I have tried using a portable gas tank and I even tried a smaller pitch prop. But the problem has never gone away. What do you think?
