Re: Replacing engine mounts
I went to a bone yard, and bought the best looking Honda Civic scissors jack that I could find for $10. The jack folds down to about 1½" and can raise to over 8".
I was able to slip this in between the motor mount, and the hull with a ½" piece of plywood under the jack to spread the load.
I then removed the top nut on the motor mount, and the two bolts that held the bottom of the mount to the FRP stringers that hold the engine mounts in place. On many boats, these are lag screws, but on my boat, the etringers are hollow, and the mounts were through bolted.
After the mount was removed, I set the new mount to the same height as the old, and installed them.
