Yeah, you mentioned that in your original post. You stated clearly what your results were. and what the fuel savings are for you and your boat.

See the second and every subsequent post ... they talk about, and question how much, if any, savngs are to be had by locking the shaft or letting it freewheel. That is what the thread is about.

Hence the question "Who really cares if they save 12 cents an hour or spend 11 cents more?"
