I love my powerhouse, I found I had enough torgue to get me out of some crazy currents in tight spots heading up the inside passage last summer. She is not underpowered thats for sure.
Those fuel numbers equate to a horsepower draw of approximately 36 HP at 8.5 knots on the JD 6068. How do you measure fuel used?
