Simple task, put a jack under, remove bolts, lower jack enuff to flip the hangers = 2 beers.
However, last haul out keel wasn't centered on the rear trlr roller, so keel was off vertical, maybe 5*....no worries I thought.
Flipped hangers, tried to reinstall properly, bolts wouldn't thread, 2 stripped out....AND one weldment felt like it was stripped, fearing the worst.
Back to Lowes for some all-thread & nutz, 3 hours later still couldn't get the b!tch to line up vertically, jacked many ways, btw, 95* here under boat.
Poured one and left the scene.
Nxt day, more repositioning the jack(s), finally got it vertical enough for the all-thread thru the hangers and into the weldments, tightened up and hangers into position.
Left the scene and poured two.
This morning, removed all-thread and inserted one bolt at a time (with blue lok-tite), fortunately I had extra bolts from last drop....all good, all threaded and tightened up properly....whew, NOW it's a 3 beer day & happy ending!
