OK.... this doesn't effect my boating and the engines are really performing nicely. But, out of curiosity, what do these numbers tell me?
5 seconds after giving throttle to bring boat on plane:
Port RPM - 3,600 and works its way to up to ~4,000 by the time boat gets on plane.
Starboard RPM - 4,400 and works it way to down to ~4,000 by the time boat gets on plane.
After boat "grabs, then rpms work identically. Temp, Oil pressure, water pressure, etc. all ok and engines act identical except when getting on plane. Hubs were checked and everything a-ok last fall.
What causes this?
