I've often wondered my actual fuel consumption on my Konsort with a Beta. I wasn't plugging the tide but did use 19litres in 7 hours at 2300rpm with a hull needing a scrub (but not that bad). So more like 3 litres an hour. I measure the fuel with a dipstick (notched sail batten) and it is accurate. So are peoples claims of 1.5 l per hour for Konsort sized boats that accurate? (Apols if this is thread drift :))
Our old Pentland with a newish Yanmar did about 1.5L per hour if pootling and its not as slippery as the Konsort. We never made a detailed record of engine hours so only really know from the 32 to 36 hour runs to Camaret or back when obviously 3L an hour would have emptied a 90L tank before we reached our destination. (one day we might get fair wind to sail the route!!!) We did use more if pushing into F6 and chop but not as much as 3L per hour, unlike the antique and leaky Bukh originally in our present LM27 which not only used more on the Camaret run, but seemed definitely thirsty banging into head seas.

The LM27 does have fuel gauge as no way to dip it. I trust it when it says full and dont trust it below that. Its about a reliable as the one on the Navigators unlamented scrapped car - so not very.

I'm a believer in the KISS principle, so a dipstick is ideal, cheap and reliable with nothing to go wrong - unlike fuel gauges... Assuming a dipstick can be used.

On the trip when I calculated my consumption there was a bit of a head wind but more there was an unpleasant closely spaced wave pattern for quite a bit (head on chop). I would not have been trying to get anything more than 4.5 knots, perhaps only 4 knots. For me it is hard to get an accurate picture of fuel consumption as it is so rare to do long trips under motor..........to accurately use a dipstick for litres used I'd reckon you need to motor for 3 hours absolute minimum.
