A bit disappointed in Sea Hunt for the first time. Guy there has not been much help finding this lock for me. I don't expect a gift, just help finding the replacement that I'd pay for.
Finally found that my lock is a Mobella which is now owned by SouthCo. Had a hard time finding their marine division, but found a local rep [who ironically is brother-in-law to an old friend]. He has been very helpful and actually went to my boat in Beaufort, NC, took off the lock and is getting me a replacement.
Having said all this, if you need a SouthCo lock for marine applications the website is
http://www.southcomarine.com/; which is different division of SouthCo. I could never access this division from their main website.
