Mercruiser 4.3 loses power and surges when hot
My '85 4.3L Mercruiser starts losing power at plane and starts surging
heavily at idle after about 30 minutes of running. The motor is not overheating and the clear fuel filter close to the carb is still full of gas. Any suggestions on where to start? |

I suggested before it was probably vapor lock. Seeing gas in the
filter does not matter, the vapor lock could be in the carb or in the line elsewhere. Take a pure co2 fire extinguisher along next time and give the carb and fuel line a squirt to cool them down and see if it runs normally again.
