hello, I got very accurate results at displacement speeds and in accordance with two year experience with the boat and consumed fuel on longer trips. But, the question is should the getting over the hump be excluded for this type of measurement? Because with 195HP diesel engine, which at maximum power consumes approximately 37 liters/hour per the book, I have measured 90 liters/hour (getting over the hump included), so I was a bit confused. That was 15 liters in ten minutes. The boat is heavy, but not overloaded, no smoke, RPM can go a bit above maximum declared at WOT. Nothing is malfunctioning. If I presume that engine does consume 37 liters/hour without going over the hump, that means that in ten minutes it consumed 6.2 liters on planning and 8.8 liters to get over the hump? Is this reasonable thinking? Please help. Thanks! I didn't find the right solution from the Internet.
