I bring mine to wide open, then throttle back just a crack.
The thing with outboards is they are not built like regular inboards, car engines, air plane engines or anything else. They run on needle bearings and not friction bearings. They are designed to be able to be run hard. Essentially they are high performance and strong engines especially if you look at how many hp they squeeze out such a small amount of CC's.
Running outboards hard is perfectly ok. Running regular inboard gas motors that hard causes issues. Don't forget inboard engines are built more for torque (lower rpm) where outboards dont have nearly the torque but are meant to be more for speed (high rpms)
The only caveat to all of this is when pushing a displacement hull
maxing out the rpms usually doesnt gain you a ton of speed and at that point really is just wasting gas. Match how you run the outboard
on your sail boat to how much gain you actually get in speed.
i.e. if at 3/4 throttle you get 5 knots and max throttle you get 5.5kts then stick with 3/4 the extra rpm
is just burning gas and not really moving you that much faster.
