Answer :
If a boat motor catches on fire shut off the fuel supply immediately.
Option B .shut off the fuel supply.
Stop the engine immediately! This is always the first thing to do in the event of a boat fire. Position your boat so that the wind blows the fire off the boat. This will help prevent the spread of fire and minimize smoke inhalation for you and your passengers.
If there is a fire in the engine compartment, turn off the fuel supply. Point the fire extinguisher at the base of the flame and sweep back and forth. Never use water on gasoline, oil, grease, or electric fires. Ask for help on VHF Marine Radio.
The solution is to keep the hatches closed and extinguish the fire with a permanently installed fire extinguisher in the engine room or a portable fire extinguisher ejected from the deck fire vent (small opening to the engine room). . Any class of chemical extinguisher used is unsuitable.
