Total newb trying to understand how to adjust a two piece manual jack plate. I've linked an image of my jackplate. https://www.t-mobilepictures.c...0.jpg
I've loosened the two 3/4 bolt/nuts on each side that appear to guide and secure the outer jack plate (mounted to the transom) to the inner jack plate (mounted to the outboard).
I'm looking to raise my set up one inch. In doing so, I had to remove 1 9/16 bolt and nut that went through the both the inner and out pieces of the jackplate on both sides. This is depicted in the image where the arrow is pointing. If I didn't remove it, the jack plate would not move up and down.
I'm concerned because upon raising the jackplate, there are no tapped holes for me to put this 9/16 nut/bolt back in. The linked photo shows the jack plate up 1in where I want it. Can I simply drill out a new hole? Can I leave this off the jackplate, seems like the two larger 3/4 bolts on each side really hold things down.
If anyone knows what type of jackplate this and may have a place where I can get literature on it, I would appreciate it.
Thank you.
The boat is an 85 Hydra-Sports VL485 DC with an xp200 on it.
