I hope anyone can help. Have 35 Evinrude ran great for the last two years. Lately when I have it at full throttle the motor begans to choke out. The boat starts to lunge foward. The motor sounds as if its starving for gas. When I back off the throttle the boat scoots just fine. As soon as I open her up the motor does it again. Now the motor is doing it at half throttle. I checked everything from the gas can to the fule pump. New line and bulb, new fule line and fuel pump. The motro dose not smoke and starts on the first try. I can run it a full throttle for the first 2 minutes before it starts to act up. Can any think of a solution? The model # 35752C and the serial is E0002023. Im good with tools and love to work on things but I need to know what fix or replace before I make things worse.
