I need help guys
The boat cranks and idles great. Runs good for about 5 / 10 minutes then drops to about 50% power. You can push the Key choke and the motor runs about 80 / 85% then returns to about 50% power. I changed the gas bulb, gas lines and fuel pump. The motor seems to run a little longer at 100% but then goes to about 50%. I have taken the carbs off and cleaned. Saw nothing, they actually looked very clean to start with. Before I put the carbs back on, I thought i would ask about any adjustments on the carbs or any other ideas anyone might have for me. I'm stumped! Help
