I had to replace the servo motor on my Perfect Pass after it completely seized up and quit working. The boat has only 100 hours and the replacement cost me about $350. Is this a common problem with perfect pass? Any way to avoid this expensive problem from recurring? I just can't live without the perfect pass!

Over 200 hours on mine with no problems and the PP system has been on for 90% of that time. I would check to see if the servo motor is mounted in a place where it can get wet, otherwise, sounds like just an unlucky instance.

Generally they only seize when they get wet. Look where it is mounted and if it is on a v-drive is it below where 2 cushions meet. Water tends to run in and that gets them. Another thing I have seen is some not so bright people empty fat sacks into the bilge and let the bilge pump empty the water. This works but a lot of water is flung by the pulleys and belts getting the servo wet.

On my V-drive with MCX, I mounted it way out of the bilge, putting it on top of the left exhaust. No water there.

It never got wet that I know of, but it does lie above the engine, right where the pads come together. I guess I will keep an eye on the new one and hopefully it won't happen again.
