Have a small leak coming from top cap of the Airmar transducer (see photo). Pulled it out, replaced the dried out cracked lower o-ring, but it still leaks. Thru-hull appears to have 2 notches in lip where transducer upper o-ring seats that look like the issue.



Is it possible the oem thru-hull is not made for the Airmar?
Never seen this before... Anyone else? Thanks
