Do you have the three or two bladed prop?
We have the "AP3 series" 3 blade version.
Are you able to access the pictures from the link in the previous post?
How about some real world numbers?
At max takeoff weight, at 85F, at sea level, climbing at Vy 75 kts IAS.
When climbing to altitude at Vy when the OAT at takeoff is 95F, have you noticed high oil temps above 230F?
