R300 Horrible fuel burn

Recommended Posts

I have an 08 R300 with twin Yamaha 350. I just purchased it survey shows perfect compression. No issues, did oil, plugs, fuel filters before the season. I am getting horrible fuel burn. Basically it’s 1 gallon per MPG across the board. So at 30 mph it’s burning 30 gal. Everything I read about the boat said it should burn 16 gph at 30 mph. Any input would be great.

Check to make sure the height of you motors are adjusted properly. My motors was running too deep and when I had them moved up on the transom my fuel mileage increased by about 20 percent.
