Description Technical Specs

This is a replacement lock engine for the popular Southco Mobella McCoy swinging entry door latch. Sometimes referred to as the door's guts, this is the main functioning portion of the latch which simply slides into the edge of your boat's or yacht's door. Each lock engine comes with a privacy lock spring for the privacy knob on locking McCoys. It will work with passage (non-locking) doors as well, the spring will just not be used.

We offer the lock engines with either a standard single springbolt or a double springbolt that reduces closing force and resists vibration. All lock engines have a brass body and you can select whether you would like the screw plate and spring bolt to be stainless steel or brass. You will also need to select your door swing from the options area above. In the last picture you can see a diagram showing how to determine your door's swing. If you are replacing multiple lock engines on your vessel, be sure to check every door.

Reviewer: Ted Smith from Sidney, BC Canada  
We needed a very elusive piece of hardware to fix a broken spring in a door latch on our Hunter sailboat. Southco is a brand used by many builders, but it is hard to find just parts and we didn't need the entire latch set. Ugly Fish was the only North American supplier who (to our knowledge) carries the "guts" So to fix a broken $.25 spring, we spent $135.00. But if we'd had to buy the entire set...$200.00 Our only quasi negative comment is that it arrived in Canada in less than a week when we were expecting a month.
So all in all, thanks Ugly Fish!
