What rpm are y’all turning? This guy claims his slows down propped to spin more than 5800 which I find hard to believe and wish dyno curves were released to the public like in the automotive world as they have to dyno them for emissions purposes, but I believe the reason for them not doing that is the 10% rule on outboards that allows them to make within the advertised number + or – which the latter would hurt sales of course if it was widely known.
