Received the kit and rebuilt both cylinders. Not horrible. I'd go on a limb and say I'm decently mechanically but many of you would laugh at my small tool collection. I ended up having to Dremel out a notch on a washer that would slide around the ram cylinder itself so I could place it on the cylinder cap and smack it down to removed the retainer ring. In hindsight I'd say it's probably a 6.5 out of 10 on the difficulty scale for a do it yourselfer. As far as bleeding out the system...definitely have a helper. Doing it myself, getting in and out of the boat, under a monster swim deck, all with a bad knee...GIANT P.I.T.A.!!! Oh well...it's done now. Thanks for the input!
