I have a 1981 Newport with a 1981 OMC 90-HP outboard engine. The outboard engine is currently mounted using only the top two bolts. I would like to install the bottom two bolts to allow me to raise the motor using the method [of having the boat on its trailer, unbolting the engine, stabilizing the engine on its skeg, then moving the boat transom by using the trailer jack, as previously mention in an old forum posting and] described here:

How difficult is this to do? Can I do it on my own or should I just have a shop do it for me?

Any tips of parts required and procedure would be greatly appreciated!

You need to first decide where you will be drilling the holes for the lower mounting boats. See the FAQ for advice. Here is the link you need to follow:

Also: IMPORTANT--the method you have pointed to employs the two lower mounting boats to help retain the engine to the transom. Also--IMPORTANT--the method you have pointed to is for engines whose mounting bracket has a slot for the lower mounting bolts, not individual holes. That method won't work if you have a mounting bracket whose lower bolt mounting locations are holes, not one big slot.

Also: IMPORTANT--you need to figure out if your boat can accommodate the standard transom hole layout. See the FAQ for more information. Here is the link you need to follow:
