Back in Sandinia, I've just began my two week, pre-season preparation work. I was going to fit three new water
pump intake bronze screens today, but when I examined two through hull
fittings that were installed last season, I noticed that all the bronze screws had corroded.
Last season, the screens were part of the through hull
(a one piece design) pictured. This year I had planned on just installing the bronze screens over the existing mushroom though hulls using an adhesive
bonding material along with bronze screws. Last year, I did the same, but as you can see by the pictures, the screws are now missing. The two that were fitted last season are part of the boats electrical
bonding system. The two to be installed won't be a part of the system.
Question: Should I go ahead as planned? Will the new bronze fittings end up totally corroded over a one or two year period. Or.... Should I instead use a marilon screen
along with bonding and stainless screws?
Thanks in advance for your replies.
