Mount your trolling motor with Isolator Bolts and shield your boat deck against impacts and vibration. Stainless steel bolt with rubber body. Initial installation requires drilling of 1/2" diameter holes. Once installed, bolts can be replaced with only a screwdriver and pocket knife without accessing underside of deck. Available: 6 pack, 8 pack.
A total waste of money for me. Bolts are not long enough for my Minkota motor base. Had to custom make SS bolts long enough too mount the troling motor. Three of the rubber extensions broke the first time I trailered my motor to the lake, I did not use lthe motor on that trip. (road is paved and is not rough and I travel no more than 60 mph on roads rated for 70 mph.) I definitely woul not recommend these things to anyone for mounting more than a very small trolling motor.
My old Orion (1977) hull is over 4" thick by the time I get through the fiberglass and the supporting wood underneath. ( don't have the luxury of a removable front panel into the bow. The rubber could not expand. It just kept spinning in the bored hole. I didn't think of that. I was so excited to just have a new front mounting trolling motor! So, off to the hardware store for long toggle bolts.
These bolts (rite-hite) are useless. Rubber is very thin walled. When installing rubber tore in half before even starting to tighten. If you must use isolator bolts because of lack of access I recomend MotorGuide bolts. I cut rubber to size and used a 1/4" fender washer and a lock nut to secure mount to bow for each bolt.
Very good fast mounts, be aware of limited life...

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!
