Hi,I don''t know what the capacity of the Garhauer is. I lift a 8hp 2-stroke.I think I could lift another 30-40lb without a problem.The quality (seems) good.I''ve used mine for 3 yrs.& for 6mos. almost daily.Maybe some of the reasons it''s cheaper is that it has a 2-pc.post,the lift arm bolts on,it''s supported by the pulpit rail,& the whole thing is removable without undoing anything. Also, most Garhauer products are less expensive,across the board. I have a 36'' catamaran & I carry my dinghy in davits.It takes me about 6 min. to drop the dinghy,put on the o/b,and go.
