I am mounting a trolling motor to a fiberglass bowrider. The problem is that there is no access to underneath the deck where the braket needs to mount.<br /><br />So--- do I have to cut an access hole so I can attach the bolts or is there some sort of anchor available (similar to a butterfly drywall anchor but marine grade) that people use to mount the motor in this situation?<br /><br />Thanks in advance for your input. Great site- has saved this new boater a lot of time, money and headache.
