Here is what they are going to be using in Powerboat P1 for the 2010 season on all the boats.
This is a torque meter that goes between your engine and the drive unit. (How they would couple to a close couple Bravo I do not know) The pic's are showing it installed upon the Apache pace boat in P1 which obviously has transmissions.
They are going to mandate that every boat use these (don't know if they have to be on one engine both as the rules only require one engine to be sealed in P1 (LOOP HOLE)) to monitor the power the engines are actually producing and then adjust weight accordingly.
This is not new technology. It is nothing but a strain gauge with a sensor that reads the engines rpm and thus the math to hp is found. I remember these about 10 yrs ago at the Ft. Lauderdale boat show in the Michigan Propellers booth (they were the distributor) but now they are going to find their way into a race boat for parity classes in Europe.
