The faucet is the Scandvik Model 10480 for a 1 1/4in cutout. It is possible to replace it without removing the sink but it took a cutting wheel to get the old one out. A deep socket and a 12in extension helped getting the new one in place. It's way too shiny for the dirty sink but it doesn't leak out every opening like the old one.
I purchased the Shurflo water filter for $60 but realized after that the Whirlpool one at Lowes is the exact same thing for $35. The filters are interchangeable so next spring, I'll buy the non marine version at Lowes. I screwed a 1/2 plywood panel (5x12in) to the fuel tank bulkhead under the galley. 1in screws were little long (thery were going to touch the fuel tank -- corrosion) so I used washers to keep them away. On the plumbing, I needed to buy some adapter parts since the filter is 3/8in pipe thread but my water is 1/2 in pipe. It took a 3/8 close nipple and a 3/8 male pipe to 1/2 in female pipe adapter at each end. I also updated the lines on the boat to PEX with new fittings since the sink lines were about 2in shorter than before. That was a lot easier than I expected. I used the 1/2 in Sea Fit stuff from Defender so I didn't need to buy a PEX tool. The PEX pipe came from Home Depot though. It bends enough that I only needed fittings at the ends. I will try to post a picture later of the install.
Thanks to Steve Laume for the idea! I'm looking forward to nice water without jugs all over the place.
