MG Xi5 or MK Ulterra?

What is the best way to attach the TM when there is no access below? I want to do it once and be done with it.

I do not want cut an access hole.

I bought a 80# thrust motor.

I was think thinking the best option is SS wing nuts after doing some research. When I have used wing nuts on other projects they are the best.

MG and MK sell kits but I have read that there are problems with the kits.

Any ideas other or better then SS wing nut?

Who knows a good installer of trolling motors?

I purchased the Motorguide Alum Mount. Very solid.

All I need is someone to attach the stationary portion of the mount to the deck. Permanent attachment. Must guarantee it will not come loose.

I can do the electrical stuff.

Who is the go to guy for trolling motor installs?

Thanks
