Progressive Automations 12V High Force Linear Actuator - 1 inch Stroke, 850 lbs Force, Industrial, Heavy Duty Linear Actuator with IP65 Protection for Agriculture Automotive Industry, PA-17

I purchased this to replace the engine hatch actuator in a 2003 380 Sea Ray. It fit this application perfect with no modifications. My only complaint is that the supplied connector on the leads is useless without the mating end. Progressive Automations should have supplied the mating end with pig tails to splice into the existing harness. Not a huge deal or deal breaker. Hopefully it will last as long as the original.

Bought the PA-17 14” versions to replace the actuators on my 2002 Sea Ray Sundancer 320. They’ve been on the boat now for a year & am happy. The 14” are shorter than the original 18”, but the housing the strut retracts into is too long to allow the hatch to close flush, necessitating the shorter throw.

I’ve been using these linear actuators for more than three years. I use it for a wheelchair lift, to get my wheelchairs in and out of my car, so reliability is of the utmost importance!It is by far the most reliable piece of equipment I’ve seen for this purpose.Customer support and technical help is superb!I’m buying my second unit, not because the first one in any way is deteriorating, but I’m using a faster model. (It’s actually the same unit, with different gearing.)Again, if I could give them 6 stars, I would!

I even called manufacturer and told them what kind of use this would get. They said it should be a good fit. Didn’t hold up junk. Sent back

Well built. Did not like the round face of the actuator ends, these should have been flat faced. The diameter of the linkage hole at the ends of the actuator are ~33/64", with the piston end hole ~.002" larger than the base end hole, which is ~.002" larger than the 33/64" oil-hardened drill rod bar stock I purchased to make linkage pins use with this actuator. I used .004" steel shim stock to firm up the piston end linkage. Progressive Automations does not seem to carry any linkage pins that provide a tight fit for this actuator. This actuator is used to tilt a 800 watt tracking PV array in the north-south axis.

Works great, very strong. I ordered the wrong size so to return it and order another. The new one works great, does the job nicely, however dealing with Amazon support regarding the return was a very bad experience. I returned it the day after it arrived, and here I am almost 4 weeks later still waiting for my $322. I’ve had to deal with no less than 7 customer service reps at Amazon , some lying to me saying my refund is just 3-4 days away, and now being told I have to wait another 2 weeks. I have a friend that ordered an expensive ( cost more than my item ) table and chair set that they wanted to return because it wasn’t exactly what they thought it would be. Amazon told them to not return it, just keep it as a good will gesture, and they would send a similar replacement …. No cost! The Amazon return policies seem to be like leaves in the wind, blowing in all different directions, just depends on how lucky you are in the return process . VERY FRUSTRATED !

have not installed them yet but i am sure they will be easy to install, and they will work great. Thank William

Quality made item through and through. No grease???Waaat?? Powerful and smooth. The 16" is not an exact fit for a sundancer 420DA.p robably just get the 14"..will be "replace plug and play". I had to modify the bracket to get the Hatch to close completely but it lifts the Hatch smoothly and efficiently far better than the OEM with no grease to maintain. The most important thing with this is to measure the compressed length of your old unit not the extended length. I made that error. I would have returned this in order to 14 but I had already cut off the connector to place it into my electrical. 6 months later I'm still smiling every time I open the hatch
