    The plate on the valve cover should give the max no-load rpm, if it's still there. If not, I would guess 2500.

    WOT RPM should be 2300, with high idle 2500.

    Check the high idle - if its 2500 (within 25 rpm or so) then 2300 is the proper loaded WOT MINIUMUM.

    2350 is what you want to prop for with a FULL LOAD. This gives you some margin when the wheels are less than perfect, there's a bit of fouling on the hull, etc.
