i had the isolater bolts for my trolling motor start to pull out. i have a nitro 640 and don't have any access underneath....do i have anyother options other than ordering another set....or is one brand better than another,i think i used the universal set listed in bps catalog....

The screws that hold the trolling motor can be tightened which causes the isolator to expand and hold the trolling motor. The isolators can be changed from the outside of the boat. Remove the screws and lift the trolling motor mount then pull out the rubber isolators.

To replace them just drop the new ones into the old hole, replace the mount, replace screws and tighten. You're done. Sometimes the rubber part breaks during removal and leaves some in the fiberglass, if this happens just knock the broken part thru the hole into the boat, then replace.

You can usually gain access underneath the trolling motor by removing a power panel or depth finder and snaking your arm/hand through. Most people do this and replace the isolators with stainless steel bolts/washers/nuts. I replaced isolators several times before I bolted them. No problems since.................Al

i removed the power panel but couldn't get my arm in far enough to reach all the bolts.instead of one larger hole there were two smaller holes behind the panel and if i made the hole bigger then there wouldn't be a place for the panel screws to hold to, so i ordered some isolater bolts from motorguide,maybe those will last longer....
