water in bildge 18sf 1977. advise pls

[dginge]

I have a 15 yr old rude on my 18sf
Notice water in the bildge after a days use. Like maybe
a gallon or two..... Checked (re sealed) live well again, Scuppers, drain plugs,
Etc etc. I have no through hull fittings. Driving me nuts...
Any ideas or experience as to where it may be coming in?
Everything looks healthy to me.... It isn't a lot but who wants water
In their bildge? I guess the 15 year engine install could be
Making it leak around the engine bracket? Haven't checked the transducer
But doubt that's it with just screws in the glass....
Help or.advise appreciated
