what kind of thru hull is best for below the waterline.i have plastic rerko's in now,but i don't know how old they are.do brass ones have to be painted? is stainless better?the plastic ones i see say not for use below the waterline.what do ya think.
my new 85 v 20 o.b. has 2 hatches in the top of the transome, it looks like theres supposed to be some type of liners in them.maybe like for storage or bait.does anyone have these?or know where i can get them.
