This is weird case. Buy or borrow stock bravo 1 prop!!!!! The prop is out of specs or your coupler is done. Stil 33% slip. Take white marker penn and draw line to the coupler, take a ride and check the marked line. Dont know how the bravo coupler fails, but the smaller coupler used with alpha drives can slip before it fails completely.

On the way back home I took some photos on the GPS speed and rpm gauge.
Now it shows 46,3 knots/ 53,2 mph @ 4400 rpm.... Yes this is weird lol.... A slip number of 30%
