[Public-List] Whitby Shop Made Through Hulls

[crufone at comcast.net]

Hello, 



How easy is it to distunguish these through hulls from the normal cast bronze variety?  My boat is a 1966 model. Which through hulls are likely to be suspect?  Even though none of them are leaking, I was thinking of removing the through hulls and just rebedding them.  Mine is a fresh water boat so I expected this to be a good way to proceed.  My original gate valves all work fine, don't leak and none are frozen with corrosion. After rebedding the through hulls I was planning on inspecting and perhaps repacking the gate valve stems and refitting them back in place. 



Hummmmmmmmmm  should I be thinking differently?
