I have a question that you guys might be able to help me with. I am going to get a bow trolling motor, and I have a high bow rail. Well, the solution that I have found it to just take the rail off. My question is there are 3 screws at each post and seems to be sealed with silicone sealant. Do you think that there are just the three small screw holes or a full size larger hole, and do you think it could be bolted from underneath?
