We like our Martec, though as mentioned, marine growth can hamper its opening properly and hurt thrust. If it does open unevenly, the throbbing vibrations let you know pretty quickly. Putting the engine in reverse and speeding it up seems to fix that problem, and then you can proceed normally. Newer versions of the prop apparently have interlocking teeth that even out the blades'' opening and avoid this problem.
