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.
