Boris, I replaced ours with a single hole, pull-out, spray faucet. Fits the hole and is much more useful with the spray or stream feature. They are $150 and up at the box stores. I found one on eBay for much less. I'm not home now or I would look at the one I removed for you. Our boats were made around the same time and should have the same faucet.
Edit. I looked at your album and we had the same faucet. Photo "sink pin rails" # 10 in Configurations sub album.
Yours might be a Scandvik faucet. They make a few similar ones. Look at,
