GPH gas usage for 270CR with Volvo 5.7GXI (320 HP)

Recommended Posts

I have a 2005 248LSC with a Mercruiser MAG MPI (300HP) and I average about 5 GPH gas usage overall. I am contemplating moving up to a 270CR with a Volvo 5.7GXI (320 HP). Does anyone have any experience with this (or similar) configuration in terms of gas usage?

I have a 270 with the 5.7GXI DP, My overall average is usually about 6 GPH, Cruising at 24 kts you can expect 9-10 GPH. If you run the boat over 3500 rpm to WOT expect o burn a lot more. It has turned out to be a very economical cruiser. Good luck, Jeff
