Default HP 500 Secondaries

At what RPM do the secondaries start coming in on an HP 500 ?

I believe they are mechanical secondaries. So it would not be an RPM but where your throttles are when they open.

They are mechanical secondaries and every boat is a little different depending on how its propped and such. They should start to open in the 4000 +/- RPM range.
