On my project list for the spring is to replace the galley faucet with a single handle, pull out faucet. I think it'll be a lot easier to use and look better too.
Something like this....

Very similar to what comes from the factory on the 318.
Fast forward to tonight. I'd really like to get a single handle faucet/shower combo for the head, but I've yet to see one that would work. On an '08 260 Sundancer at the boat show this evening, I saw just that.
Here's a picture from Sea Rays parts diagram showing the faucet.

Seems like an upgrade from the two handle version currently on my 268.

Has anyone done something similar? I remember a thread from last year regarding galley faucet replacement, but nothing about the head faucet. I checked and the 318 has the same head faucet as on my 268...
