OK.. So I took my trolling motor off of my aluminum boat. It has 6 holes which were bolted onto the aluminum boat. But now I want to put it on my fiberglass boat. I'm not sure screws would hold. I can't get into the underside of the fiberglass to use a nut and bolt so I'm wondering if they make an anchor like a sheetrock anchor type thing?? How do you normaly do this?
Logan I'm guessing the fact you cant get at the bottom to put some nuts on the mount this is an older fiberglass boat. If this is the case the fiberglass is pretty thick. That being said you probably could just screw it in. It does not take much to hold that trolling motor. I would use the biggest screws that fit your motor and cover them with Locktite when you go to put them in. The Locktite will prevent them from loosening up when you transport the boat. Give it a try and see if you can live with it.
If you feel it is just to weak, than go with the Sheetrock anchor like you were talking about. Buy the biggest one you can. The smaller ones strip to easy. Once again I would put Locktite on the threads.
I threw some locktite on and screwed her in without anchors. WallDigger, You were correct in assuming it's an older fiberglass boat and yes, the fiberglass is thicker than I anticipated.. I tend to be rough on things So I was worried that dropping the motor in repeatedly would start to cause problems. But It's holding just fine and feels strong.
