Beneteau Oceanis 31 - Seacock Corrosion

[doug748]

But surely that is the whole point. The diligent owner takes steps to avoid these well-publicised problems, by carrying out regular checks/replacement of rigging fittings, keel bolts, rudder bearings and stocks, etc., etc. Replacing potentially problematic seacocks is just one of these, avoiding failure down the line. I am certain that mast loss due to rigging failure is far more common than boat loss due to seacock failure but insurance companies do not load the premiums of boats with masts as far as I know.

There should be a forum award for this sort of patient reply.

The raw water inlet to my Yanmar 3YM20 is badly corroded and needs to be replaced.
Boat is now 6 years old and all the other seacocks look OK.
The only difference I can see is that there is a strainer on the outside which may be setting up some kind of sacrificial current.
Any ideas on the spec & supplier for a replacement? (UK)

I think Mistroma has it right with the wire reinforcement in the pipe.
