I used 1 a-frame, one 3 ton chain hoist, 3 straps. One strap thru the eye of the boat, one under the front third of the boat and slide another under the boat where the actaul motor sits. The majority of the boat weight sits on the rear two straps while, the front strap under the eye is more or less to help out with balance. If you can not get the rear strap under the boat where the motor is, I grabbed a 4"x4", cut the top of it to the shape of the bottom of the boat and uses a hydraulic jack to raise it just enough to get the strap under. I then used a series of cinder blocks and notched 4"x6"'s that were notched to cradle the boat (I believe 4 total). Reverse the process when you want it back on the trailer.
with the engine still in it? Im having my trailer redone, and i dont want to pull the engine to get the boat off the trailer.
did you get it off??? just curious, who is re-doing your trailer???
