I'AM A FIRST TIME BOAT BUYER LOOKING AT TWO BOATS. ONE HAS A 130HP HONDA 4 STROKE THE OTHER HAS A 6 CYLINDER MERCRUISER STERNDRIVE. WHICH OF THESE CAN I EXPECT TO GET THE BEST FUEL ECONOMY? I WILL BE IN SALT WATER MOST OF THE TIME. WHICH OF THESE TWO WILL GIVE ME THE BEST LONG TERM SERVICE? THANKS. THIS BOARD HAS BEEN A GREAT HELP
