I have done a couple of jack plates including my own and with the right tools its an easy job. I use a come a long attached to the cross beam of a car hoist and the merc lifting ring to raise and lower the motor. Works great. Its a 2 man job tho if you want it to be alot easier. The lifting ring is a must tho. I have always used grade 8 hardware and I never have to worry about gauling the threads or lubing the threads of the bolts. Use 3M 4200 silicone also.
