if you take it easy getting on plane and keep of the stick when getting air either motor's will be fine on a xr for a while .
i had an xr on a 2005 28 pantera with a 600 ci 750 hp motor and the drive lived for over 80 hour's until i sold the boat and from what i herd the new owner put another 50 hour's on it before a rebuild , so it all depend's on how you are going to drive . iv herd of guy's blowing xr drive's with 525's but they do whole shot's from a dead stop :(

lot of nice looking motor's in the oso classified's
