3500 Open Fuel Consumption

[Chris Burkard]

The 3500 Open is a great boat with diesels. Tiara only built a few 35s with gas engines and usually for short season areas where diesel is hard to find. I have run a gas 35 and it runs well, just slow and with a much greater fuel burn than the diesel versions. Cruising speed 20 to 21knots getting .75 mpg. The Cummins diesel version cruises between 24 and 26 knots getting 1.15 and 1.2 mpg (salt water, mild temps, calm sea conditions and normal loading). Fresh water will produce slightly lower speed and slightly worse fuel economy.
