Good morning,
I recently changed props to the spitfire x7 19p and raised the motor one hole ( i can still go up 2- Merc pro xs 115).
The porpoising issue is completely gone, running about 44 mph (gps) with 2 full sized adults and gear.
Wondering why I am only seeing about 5200 RPM's on my stock tach... I know they are not the most accurate but I am no where near the peak performance for that motor. Is this bad for motor? Should I go up another hole? Prop change?
