Hows Your Fuel Economy With The R family of Mercury Racing Outboards?

[DrCatcher]

I am super impressed with my fuel economy numbers I am seeing on my Mercury Racing R Applications. What is everyone else seeing? 

These numbers are boats loaded ready to fish... 

36 Yellowfin Triple 300R Eco XP props 1.65 mpg @ 40 mph

24 Yellowfin Single 450R Max 5 prop 3.95 Mpg @ 45 mph

24 Yellowfin Single 300R Eco XP prop 4.25 mpg @ 40 mph 

17' technical flats boat 60R Vengeance Prop 8.2 MPG @ 28 mph 

With todays rising costs in fuel great fuel economy is a huge help keeping our bottom lines down, especially as a charter fishing guide. Feel free to ask me questions about my set ups here on this forum.

Likewise very pleased with the performance and fuel consumption, twin 300R's on a 35'cc deep v. Burning around 48l/h per engine at a cruise speed of 35-36 knots.
