Found out from Thom at Hydromotive why the new 25p Q4 OT Round Ear has a slower hole shot than the 24p Round Ear on the 225x PM.
The new ROS had an open exhaust 'snout', 'cuz it was set up for an 'over hub' prop.
The 25p is a thru hub prop and requires the exhaust to optimize performance.
Checked the parts manual and sure enough both plates are offered....I just fabricated an aluminum plate and installed it above the hole'e one.
Will update performance this weekend.......if the weather co-operates.
