Out of curiosity anybody know what the fuel burn estimate might be on a 75' motor yacht with Cat 3412 running at about 9 knots and what the generator may use per hour?

Re: Fuel Burn

Re: Fuel Burn
Should be about 17/19 GPH combined based on other 70/80 footers I ve run with 3412Es/C32s
Generator burn depend on load. Assuming about 20KW at typical half/three quarter load burn should be about 1.5 GPHPascal

Re: Fuel Burn
2002, must be 3412Es. Great engines. I put 4000 hours on a set and they passed survey with flying colors at 5500 hours. Nothing done beside routine maintenance
