MotorGuideMGA015PB6 Mounting Isolator Kit — Absorb Shocks, Protect Electronics — Includes Corrosion-Resistant Bolts — Set of 4

I had to install a new trolling motor on my aluminum boat. Access to the underside of the deck was non-existent. These inserts worked extremely well and hold the TM bracket securely in place. You will need a 1.2" drill bit for the inserts to fit.

BUENA SUJECCION PARA MI MOTOR TROLLER.SOLO QUE POR MI MODELO DE TROLLER TUVE QUE COMPRAR POR APARTE TORNILLOS DE 4" MAS LARGOS PARA LOGRAR LLEGAR A LA ROSCA

It fit properly

Serves their purpose

These are actually very nice mounts and easy to use. I highly recommend, however anyone ordering should order a second set as a spare. The very design of these will not last forever. In fact, my first set of these just failed on the water. Glad I had a second set onhand on the boat and a phillips screwdriver in the boat toolbox. Took 15 minutes to replace with a new set on the water.Now for the problem...the design of the mounts are to isolate shock and torque from the mount holes through the fiberglass boat deck. They truly do the job for this....no deck cracking what so ever after three full years of fairly hard use. However, this advantage comes at a price. The mounts are rubber and will eventually tear through/separate from the brass threaded tightening sleeve. When this happens, the mounts will have no grip and pull straight out. Fortunately, my MG gator mount has four of these, and motor torque only tore thru the 2 isolators on one side of the mount.When I replaced, I did all four of the isolators....glad I did, as the other two were about to fail as well. When the two did let loose, the mount looked as if it was going to fly off the boat, but the other two held. Lesson learned....although you're not supposed to have to get access below the deck to use these mounts, I WILL be adding a washer and nylon lock nuts to make sure the next time they fail, the mount doesn't try to jump off the deck:) My heart can't take that anymore!Excellent mounts though, I'm back here to order two more sets for spares!
