Well I have my drives apart just want to go through them, uppers are like new. Lowers have some wear, nothing bad. They are laying on my work bench haven't decided weather I going to put lowers back together and swap them with each other ( spin them the other way) or put upgade kits in them and make the lowers XR's. Eather way it doesn't cost me that much cause I get my parts at cost, and labors free, plus I get to hide in garage smoke cigars and not have to listen to the wife, which is a good reason why I tare my boats, cars and bikes apart every winter. My drives are 1:36's any body else running 1:36 on thier 33 Powerplay. Motors are 502's maybe 450-500 hp realy don't know. Judging by the paper work I got with boat the motors were built with parts that they should 500's. Boat cruises and stays on plane at 2200 rpms with 4 blade 24p. It will run 80 with 3 blade 25p but doesn't get on plain to easy.
