Product Features

• Made by Motorguide

Product Description

Absorbs shock and protects electronics. Ideal for mounting all marine accessories, electronics, and trolling motors without having to get under the deck or behind the console.  The rubber limits vibration and provides a solid installation. MotorGuide factory isolators come with many of our mounts and are a quick and simple way to mount a trolling motor with limited access.  Each rubber isolator has a molded-in nut inside the small end, that when tightened up against the underside of the deck by the stainless steel bolt forms a rubber mushroom shape that hold the mount in place.  Each kit comes with 4 stainless steel bolts and 4 rubber isolators, along with mounting instructions.

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!

2.0 out of 5 stars Not suitable for stronger trolling motors, September 29, 2011

These isolator bolts seem to work fine on 12 volt trolling motors, but on my new Minn Kota ST-80, they just did not hold up. After a month and a half, they just pulled through. After talking to my dealer here who claimed he never saw problems with these bolts, I decided to give them one more try. I thought that perhaps I tightened them too tight. Well, the next set I was very careful with, even counting the number of turns on each bolt. About 6 weeks later, they failed again just like the first set. I almost lost my motor when I went to full speed. I now think that my 80 lb thrust motor is just too strong for these bolts. The problem also may be related to my using the Minn Kota RTA 17 Quick Release bracket. The holes on this bracket are very close together, so the torque on them must be much higher than if the motor was mounted directly to the deck.

I now am trying the Minnkota Mkr-8 Quick Nuts. I had to widen the holes in the deck to 5/8", which was a little difficult because the only 5/8" bits I could find were not the kind that would self center within a 1/2" hole. I created a guide to keep the drill centered over the hole. Anyway, the Quick Nuts do not isolate the vibration quite as well as the Motorguide Isolator Bolts, but thus far, they seem to be holding up very well. The trolling motor is much more firmly attached.

So some people have good luck with these isolator bolts, but if you are using one of the newer, stronger trolling motors, I would advise not using these. I have uploaded a picture of the last set of Motorguide Isolator Bolts to illustrate what happened to mine after only 6 weeks.

4.0 out of 5 stars good product but not for minn kota motors, June 26, 2011

They seem like a good product but they do not work well with minn kota trolling motors. You need a 4" bolt and they come with 3" bolts. Minn Kota Maxuum trolling motors have a very thick base which requires a 4" bolt. When I hit the switch to run the motor it rocks a little and I think eventualy it will work its loose. Just to much leverage for the rubber shanks to handle.
