Polling other Chaparral Signature 310 owners, year models 2004-2009 with Volvo 5.0 engines with dual prop drives to see what sort of fuel economy you're getting? My fuel manager (based on what ecm fuel flow shows) is showing 1.0-1.1 MPG @ 25 MPH but on a recent trip it was showing .9 average when the fuel pump after topping off the tank again shows .7.
Post yours so I can compare if my heavily loaded boat for the trip was out of the ordinary or in line with others under "normal" or heavy loads. Please estimate you boat load (light, medium or heavy - actual weight not required) when posting fuel economy.
