Propeller exhaust tube lengths
It has come to my attention that Mercury racing is now selling the Bravo 1 propeller with different length exhaust tubes.
There saying a long tube has more stern lift and a shorter tube, more bow lift and higher top speed.
Has anyone done any testing on exhaust tube lengths??
My Banana Shark Rib runs very flat, so I am about to start testing any help or advice with this would be great.
