    3.7 to 4.3 swap

    there are things that can be done to improve the 3.7 reliability, however you are correct that it is not supported from a parts level very much. from that point, any of the V engines would not have you digging and looking for "good used parts" however that point just on the edge of dropping...

    3.7 to 4.3 swap

    marine spark-ignited I/O motors burn 0.4# of fuel per HP per hour. so fuel consumption is solely dependent on load and commanded throttle. if you load a 5.7 liter motor and a 7.4 liter motor and a 4.3 liter motor to 150hp for an hour, they all burn 60# of fuel in 1 hour (8.8 gallons)
