Thru hull fitting

[Trey5684]

Does anyone know the size of the jam(?) nut on the inside of the hull(bilge) for a thru hull inlet fitting.

They come in a pair. They don't sell just the nut. You'll need to determine the size of the through hull fitting and buy a new one, then use the nut from or completely replace it.

IF it's a 2004, and the through hull is nylon and all of you through hulls should be replaced at this point.
