Outboard Motor Dyno Test

I initially thought I had a fuel flow problem so I took it to a shop and they said they ran a Dyno test on my Johnson 50 HP and that the test showed proper fuel flow so they ruled out my carb & fuel pump as being an issue. I don't know alot about the Dynomometer and what it can do, but I thought it just gives a torque or hp curve. Can it actually measure fuel flow as well?
 
The 'dyno' itself just measures torque and usually has a tach (to yield HP with a bit of math).... it is quite possible the shop has invested in a comprehensive test bench (separate fuel flow meter)which they may refer to a 'the dyno'....I'd suggest you ask "how did you do that?"
