1999 Johnson 70hp max RPM

[Roccoi]

New to boating and just picked up a 2001 Grew 17ft with a 70hp 2 stroke johnson.
Was wondering what the max RPM would be, I find it revs high. About 6000 full throttle.
Should I change the prop or leave it, this was with a light load in the boat, just my wife and I.

Thanks

I'd leave it. When you load the boat down it should drop to around 5500 rpm which is where you get max HP..
