Anyone know how big the fuel tank is ? I seem to remember 8 gallon , checked the brochures etc but nothing . Just currious for calculating range.

It's precisely 41 litres.

You asked about 'range'. My estimate would be about a half gallon (2 liters) per hour.

That depends upon a lot of elements. Sea and Wind conditions, salt water or fresh water, currents and tides, at 60% throttle with a relatively empty boat in fresh water I used to get 1 litre per hour. It's really hard to attach a number to this as everyone is different.

Last summer I motored 95 miles in flat water with no wind or current. Took about 16 hours. About 2200-2300 rpm. Boat pretty light as we were transiting to a race. I seem to recall using about 1/3 of a tank which roughly correlates to Bill's 1 litre per hour estimate, under optimal conditions.

Yes, I agree that fuel usage varies. I was thinking in terms of an annual long distance regatta that we travel to. We have a crew of 4 with a loaded boat pushing at hull speed. We'd be the worse-case scenario for fuel efficiency. john

Always nice when you have a question a great group of people that step up right away - thanks all . As for my consumption I was guessing about 1/3 gallon an hour and 8 gallons . Never really an issue at all for what I do but still nice to know .

Anyone have any comments on how accurate the fuel guage is ? Never run mine down , but is a 1/4 tank really a 1/4 tank? Just currious .

They are not the most accurate gauges. The rule of thumb we go by is not to let your tank go under a 1/4 on the gauge. This seems to prevent running out of fuel and having to do a low pressure and high pressure bleed. Some boats can go under a 1/4 and some are near empty at a 1/4. To check all you need to do is remove the 6 screws holding the gauge and look in the tank. Remember that due to waves and boat motion the fuel will move around and too low of fuel will allow air into the fuel pickup tube. Bleeding these engines can be a pain so it's best to never run out of fuel.

That is about what I figured . I never let her go below 1/2 but 1/4 is a good rule .
