only way to really know is to run it, back then some had limiters at all different RPMs, I have found some had none. Do you know if it is a digital or analog box?

My stock 200 box would only turn 6200 no matter the load, and didn't like more than 6000 with much of load, After sending to Dennis Hoffman, same prop light load 7200

I turn mine 85-600 with stock rod bolts in a promax for short bursts. I wouldn't recommend it though. 7200 should be no problem.
