Goal is to find out where the motor makes peak HP. I didnít ask for prop advice but somehow that got mixed in. No one seems to have a dyno chart of the engine which is unfortunate.

Pitching for 6000 (or max rpm) is a good rule of thumb. But if the motor is making its max HP at 5800 then for my application I would disagree. The question wasn't what RPM to prop for, but rather...

This is bad advice for the Mercury V8. It does not have a traditional rev limiter like other outboards. It will never go past 6000. If you underprop it, it will limit the throttle as you reach 6000...

It shows my motor at 221kw at 5800rpm which is 296hp.

I would interpret that as meaning the engine is making peak power at 5800. (Which is kind of what I feel based on running it) But your saying...
