I've thought about that James, I've never heard of anybody reasonably
hooking a dynomometer up to a prop shaft, but I'm sure it's been done,
in high-performance marine use.


A decent marine service shop will have one. They are portable and put a
load on the engine shaft using hydraulics. I've seen them at a couple of
shops around here.
