How can I lower the possibility of water trapped inside the fuel system being drawn into the engine?
The first issue is to prevent the water from entering the system. The second is to determine how much is in the system; if over a quart, you cannot effectively eliminate the possibility without draining the tanks. If the amount is small, Mercury offers Marine Dri-fuel both under the Mercury Precision Parts or Quicksilver brands. Dri-fuel and Marine Fuel System Treatment and Stabilizer are designed to absorb water, allowing it to pass through the engine. If water continues to accumulate and create problems then contact your local dealer for other alternatives.
