Checkmate ZT 280 what is your max RPM, i only turn 4650 max

about 5000 rpm 4650 way to low.

any of you 33 lightning owners ever notice what your oil temp gauge reads. I have one reading 190 and the other 220.

After quite a bit of research, I have found out my issue with RPM and speed . If you have a Maximus prop made between 2006 and 2008, mercury had changed the way they shaped the props during these years causing the belly of the lobes to be too large. This change wound up costing a few hundred RPM and 3-4 mph, I found this out Thanks to Brett @ B Blades and confirmed by Nick at Mercury Racing. Mercury realized their new process was a screw up and returned to the prior method of shaping the props in 2009. The letters inside the hub of the prop can tell you what year your prop was manufactured.
