Hrs on an outboard question.

They're designed to operate there, but not all the time. A lot of rotating mass at high rpm for long period of time. You take larger engines that is a lot of stress. A car engine while designed to operate above 5000, is operated daily at +/- 2000 rpm. Double that to 4000 the 150k to 200k is now shot before 100k or less. I've seen pumps operating at 3600 rpm 50 years old, 1750 rpm pumps rarely last that near that long, can't say never but most do not. Best analogies I have.

Outboard motors aren't car engines, outboards are designed to run constantly at max RPM car engines aren't.

Agreed!
