Garry. Be great if you could document all your recommissioning tasks on the MSOGphotosite.com so they are easily accessed in the future by others. The email listproc is a bit clunky for searching and photos are not archived. :: Dave Scobie :: M17 #375 SWEET PEA - m17-375.com :: M6'8" #650 :: SV SWALLOW - sv-swallow.com On Tue, Apr 2, 2019, 7:55 AM Gerry Lempicki via montgomery_boats < montgomery_boats@mailman.xmission.com> wrote:
Sure, but I cheat a bit (I have a gantry). To start, I backed my trailer up so the tires ended up on blocks about 3" off the floor. I then chocked the tires and disconnected the tow vehicle. Then I lowered the front trailer jack as low as I could so the stern came up higher off the ground. I installed the 2 rear stands and chained them together. I then used my floor jack and a few blocks to lift the front portion of the trailer enough to level the boat.At this point I had my gantry over the boat just forward of the stub keel, and I ran a strap under the boat hull up to a chainfall. By taking up on the chainfall I was able to lift the boat off the trailer. Lowering my floor jack and using the trailer jack allowed the trailer to drop further away so I was then able to ease the trailer forward and down the ramp blocks I had backed it up on, and rolled it outside. Then I installed the forward set of stands along with the the V stand on the bow, and once the centerboard was out I set some of the boat weight on blocks under the keel (by lowering the stands a bit (along with letting out on the chainfall). So the gantry crane makes it like cheating. If I didn't have that I would have had to jack, block under the keel, inch the trailer forward, jack, block, inch forward, and repeat until I cleared all trailer side to side frame members and axle. This would have left the trailer on two rear stands and blocks under the stub keel. I would then get the front 3 stands in place. Someone has a youtube video showing this method. In reality my move was not quite that easy because of the long splice on my centerboard pennant; it interfered with raising the CB all the way. I don't know how they regularly used the boat trailer this way; the CB was low hanging enough that it would hit a trailer cross member when trying to pull the trailer out. Fortunately my brother was visiting, so he lifted the CB with a 2x6 against a frame rail while I eased the trailer forward. He was then able to ease the CB down behind the last crossmember.

great shop GERRY, can you tell us your procedure for lifting the m 17 ? On Mon, Apr 1, 2019 at 5:03 PM Gerry Lempicki via montgomery_boats < montgomery_boats@mailman.xmission.com> wrote:
Thanks! Yes, about 11 years ago my wife was tired of seeing me working out in the mud, snow and rain; she said it was time for a workshop, so what could I do but go along with it? LOL Best thing we did here. On Monday, April 1, 2019, 8:20:07 PM EDT, Keith R. Martin < keith.richard.martin@gmail.com> wrote:
