All the transom through hulls are leaking. 2 livewell and the transom plug. Is 5200 the best for through hull installation? Does anyone make solid replacement fittings? I have no need for the livewells and would just as soon not have holes in the back of my boat.<br /><br />How do you remove the metal tube that the transom plug fits into ?<br /><br />If I go with new metal through hulls someone explain the "hull bonding" thing to me.<br /><br />Thanks<br />rj
