You need to refill your boat when should you turn the power ventilation system?

You should turn on the power ventilation system before refueling your boat. This helps to ventilate any potential fuel vapors that may accumulate in the engine compartment, reducing the risk of fire or explosion. Ensure the ventilation system remains on during the refueling process and for several minutes afterward to clear out any residual vapors. Always follow manufacturer guidelines and safety protocols when refueling.
