I have a thru-hull that does let water come into the mounting section of my boat. That water does not actually leak inside the bost just in the back part (see picture. I circled were its mounted). It seems that it let's water flow freely in and out. Is there any terrible risks with this as it does not leak into the bost itself? If it is an issue what is the best route to resolve this. I have my mph and transducer wire feeding through it. Thank you
