2004 330 Express:
Is this factory, or a subsequent repair? Both the Generator AND Air Conditioner strainer have the same plastic fittings as shown in the picture. The AC also has a plastic fitting at the water pump.

Is this factory? As my generator thru hull ball valve has failed "OPEN", this has me a bit concerned. This may be ok if the ball valves are kept closed except when operating, I'll certainly replace with bronze and double clamp at the next service.

Thoughts?

Plastic is OK as long as it is rated for marine applications ( nylon, Marelon etc). Fittings like PVC,ABS should not be used

I have an 2007 330 had the same plastic fittings, I decided to replace with bronze ones from Jamestown distributor, not very expensive, worth the piece of mind.

The seacock condition is much more important. You may be able to free them up by taking off the hoses (out of the water of course) and lubing both internally and externally.

Same fittings on my 2003 330 Express - I'm sure they are factory installed.

The lever and shaft moves freely, however the valve does not close. These are Apollo valves, at first I thought they were residential quality, then I saw on their website they do have a marine part. Anyways, I think I will be replacing all the ball valves soon... Thanks
