I have a Powerwinch 31 on my 2530 and am very pleased with it.
I originally installed the old Powerwinch 30 on my boat. After two seasons of walking up to the front to free jammed rode or to put additional pressure on the rode because the gypsy didn't catch the rode well, in addition to sending it in for repairs, I was real unhappy with Powerwinch. I finally sent it back to the manufacturer for a second needed repair; broken gears again. I spoke with Powerwinch about the problems I had and told them how unhappy I was with their product. The customer service rep admitted that the Powerwinch 30 had several design and manufacturing flaws. Two of them being a poorly designed gypsy and plastic gears.
Their customer service was good and for $200, they upgraded me to a Powerwinch 31. It would have been much better if they would have upgraded me for free.
That was three years ago. I've had three years of trouble free use with the 31 model. The retrieve is quick and the free fall is great. I use it often for inshore wreck fishing and anchoring up while swimming. And I'm not babying this windlass. Its hard frequent use.
Depending on where you're shopping, make sure you don't get the old Powerwinch 30. Make sure its the newer 31.
