Just removed a Yanmar
3GMD from under the galley
and dinette seat in my Freedom 32 cat sloop
by myself. No "A" frame required. I just made a lifting beam out of three 2x4's 36 inches long and screwed the three pieces together with drywall screws to create a 4x6 beam. I laid this makeshift beam outside and across the main Lewmar hatch
over the dinette (clamped in place with bar clamps), and then lashed about 6 turns of half inch yacht braid in loose loops around the beam so I could put the lifting hook on all six loops. The lift
I used was a Harbor Freight 1 1/2 ton ratcheting chain lift (NOT a come-along). I also used a Harbor Freight engine load leveler. (search thier website, it's cheap
and worth it's weight in gold = $18.00) The load leveler was invaluable because as I began to lift the motor
it also moved forward. When it moved up and forward I used a rubber mallet to pound a couple of wood skids made from 2x4's under the front motor
mounts. Then used the load leveler adjusted for rear lift to move the leverage to the rear of the engine. Cranking up again the rear motor mounts moved up and I was then able to pound the skids under the rear motor mounts. Now the engine's four mounts were all sitting on the 2x4 skids about 4 feet long. Think Skis... Then I just continued lifting and that dragged the engine up and forward onto the skis and into the main salon
. A photo
is worth a 1000 words.
The hardest part of the job was the anxiety of trying to figure out how, me, alone was going to get this done. The actual doing of it was not that hard. (getting the bottom nuts off the motor mounts under the fiber glass channel beds was worse than the enitre motor lifting and moving). Once the engine was sitting on it's skids in the main cabin
I leveled the load leveler and lifted it up again and lag bolted the motor mounts to small blocks of wood so I could slide it aft (on carpet) and then the yard crane lifted it out of the boat. In your case you could just work on it in the main salon
. Once the load leveler is on it you can lift it, turn it, whatever you want easily. Good luck...
