The max rpm for that
engine is 3600. We run ours at 2800 as a full "cruising speed", but really just run them at whatever rpm meets our requirements. For example, when running just one engine (most of our usage) in no
wind, we run at 2800. If running two engines into an anchorage or punching into
current, then usually 2400. If needing to get someplace fast, then two at 2800. If motorsailing in very light
wind, then one at 2400.
