May I ask, What engine, what boat?Our engine is actually 18HP. (Although designated a "20" model. We "budget" @ 1.1 l/hr, but, looking at my spreadsheet, I see that the last 203 engine hours has given an average consumption of 0.92 l/hr - of course, there's quite a bit of idling & lower speed manoeuvring in that figure. The official manufacturer figures are 1 l/hr @ 1800 revs and, interestingly, 1.6 l/hr @ 2200 revs.
