Does anyone have a spare deck fill cap for the water or fuel fills from an 80's vintage Ericson. Lost my fuel cap overboard when the safety chain broke and all the replacements I can find are just a little too small.
Most one's I can find have an outer thread diameter of 1 1/2", but the caps on my boat are just a bit over 1 5/8". I'd call it 42mm, but the thread spacing doesn't seem to be metric pitch. Also very interesting the thread teeth are cut at a 45degree angle rather than the 60 degree which is standard for screw threads like this.
Don't know why someone would have such a non standard part nor why Ericson would use it, but if you have a spare I'm really interesting. The bathtub plug on my fuel fill looks kind of tacky.
