WOT rpm on 85 Mercury Black Max 150

[dkpz64]

What should be WOT rpm on 85 Mercury Black Max 150? I just had my boat out and it is running good. Had it at WOT and the rmp's were just over 6000. I think that is high. I'm trying to find video's on but can't find any. If I have to adjust it how do I do it?

It's a 85 Ranger 375V. It has a 19P on it.

Max RPM is 5000-5500 .....Idle RPM in gear is 650-750 RPM, this is in the water not on a hose. RPM on hose is around1100RPM
