Blower duct

I was wondering if anyone knows the diameter of the bilge blower ducting. I was going to replace mine. It is a 2005 320. Thanks

It should be 4”.

I agree, should be 4” . I justreplaced them on my ‘08 330 and they were 4”.

Tell me where you found the best price - about to do mine!

I used Trident blue poly duct. I purchased from Marine outfitters. It is much more ridged than the white flimsy original hose. Was harder to install because it is not as flexible but will stand up and last longer $11.00 per foot
