I've got a 1650 with the rear lift, and I'm wanting a land plane. The one I'm looking into weighs 233 pounds. Xtreme has there 3 point conversion and they say it offers 35% greater lifting capacity over the stock rear lift. My question is, what is the stock rear lift capacity? I've looked for about 3 hours online and can't find anything that gives a spec. Thanks in advance guys...
