Polaris XP Bought 2014 850 HO engine September 26, 2015 Will this be an easy swap for my 2009 850xp? Motor blew and I can get this engine for 1800. Buddy wrecked his with only 286 miles on it. Has the transmission too, I’m just wondering if the 850 HO is gunna be a problem?? Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) Related
