Hi Guys, I am curious of your opinion. I have a Skagen 53 motorboat with twin Yanmar 6LY-ETP 480 HP engines. The boat is capable to cruise at 20 knots, but as she is built something like a trawler, my typical cruising speed is 8 knots (at 1800 rpm). Except extreme weather conditions I never feel tempted to cruise faster. I read, however, that the engine needs to run full (or at least 80%) throttle regularly (somewhere written 20-30 percent of the time used). Apart from burning much much more fuel (3-4 times per mile), I simply not enjoy fast cruise. Is it really necessary to run the engine with full load or it is only an unfunded advice?
