New thru hull

user 10933 · May 12, 2024

Hi guys, I am trying to replace or find a replacement for my thru hull for my live well through the transom. I want to go with bronze, yet I can't find the right dimension.I have a 2023 2120 sc. I just installed a 48gl blue water. The thru hull on there now is a black plastic.
The dimensions are for a 1 1/2" hose
min hull thickness: 3"
thread diameter: 2 1/8"
cut out hole: 2 3/8"
flange: 3" up to 3 1/2"
I have been struggling trying to find the proper fitting. It could be, at this point, the same black with ss face. This boat has never even touched water yet. From the factory the hoses and ends were filled with sealant and thru hull had a crack. Just want to get her fixed and get fishing. Please any help.

Do you have a picture of the fitting you're talking about?

That seems like a pretty huge flange for a 1-1/2” thru-hull fitting.

This is about the closest I could find spec-wise, thickness being the difficult parameter. But the flange face is going to be much smaller.

Have you contacted Parker about this?

Manufactures don't do it a Lot of times, but the fitting your talking about I like to see screwed into a Seacock. That aside. Bronze below the waterline.... 3/16 Stainless above is what I like.

This is the stuff you have to work with... You may or may Not have to mod the hole in the boat. The items above are fairly Standard.

The cut out hole is 2 3/8' large, I am going to contact Parker today. For a 2120 I don't get why. The hull thickness is 2 1/8". I was thinking on the bronze, my hoses are all 1 1/2". I know there should not be that much play. I ordered an Attwood 1 1/2" ss, the thead diameter was 1 7/8", The thru hull swam inside it. Lets see what Parker says.
