Re: Outrage 21 Yamaha 200

There's no reason not to run it up to redline from time to time. The thing to avoid is spending excessive time in the low midrange, where you are just barely planing, struggling to stay on plane, or plowing along at high, sub-planing speed. All of those are demanding a lot of power, but not flowing ...
