When the motor is fitted in the outboard well which is sealed from the inside of the hull and drained and vented overboard,the remote fuel system is fitted there with long runners for very slow ideling and low rpm torque,and short runners tuned for 6000-7500 RPM with a switch over between the two.The long runners charge the cylinders well and very slow idle is great for a boat.The fuel cells are fitted midships in the hull and are sealed from the inside of the hull and drained and vented overboard.
