Replacing Lewmar hatch handles

I have a couple of large Lewmar hatches. The handles have degraded from UV. They are the kind with red latches so they can be locked from the inside.
I bought replacement handles from Defender, and they look the same as the ones I removed. However, I cannot figure out how to prevent opening from the outside! Whatever position I put the red latch, a simple turn on the external handle opens the hatch.

After some digging, it seems possible I have the older style “super hatch”, no longer supported:

Is there any reason the newer handles would not work on this hatch? It closes fine, just can’t lock it from opening from the outside.

Appreciate any ideas or suggestions.

Re: Replacing Lewmar hatch handles

Apparently, there is no available Lewmar hatch specialist on the forum. I'm sorry you have not gotten a response.

Let's try to think it through.

From the looks of it, the red tag simply stops the rotation of the handles, so the bolt stays extended. It should insert itself into a non-rotating part when you lock the hatch.

One avenue is to take it apart and see why the red tab is not stopping the rotation. It could be that the new core doesn't have a notch for the tab to go into. Another approach would be to reuse the core and lower parts, while replacing the handle on top that has been UV damaged. A third would be to repair the damaged handles with epoxy, either molded around them or painted on in several layers.

At any rate, if you are careful in your disassembly, in a place in which small spring loaded parts cannot run and hide (I used to use a buttoned up tent), you have little to lose in figuring out how the mechanism works. Therein lies the clue to how to make it work. Good luck with it.

Re: Replacing Lewmar hatch handles

the little red lever engages with the non-rotating part of the handle. This part is kept from turning by a knob that engages in a blind hole in the lens. There are different Lewmar handles for different lens-thicknesses 8Ocean series handles are slightly different from Low Profile series handles.
Why not post pics of your installation?

Re: Replacing Lewmar hatch handles

& there are no spring loaded parts & "painting" with epoxy won't repair your handles.

Re: Replacing Lewmar hatch handles

going through their spares section I see, that apparently now they have included the parts for Ocean & LP hatches in their handle kit (It's been 3 years now that I stopped working for the local distributor...)
btw: you dont have to mount the handles to see if the lock works (this needlessly wears the "thread" in the plastic): you can just fit them together & see how it goes

Re: Replacing Lewmar hatch handles

Thanks all for the replies. I found that one of my smaller hatches had the newer handles, and disassembled those. As "double u" noted, there is a shallow depression in the lens that engages with the handle to stop it rotating. This is not present in the first-generation hatches. But after now replacing several of my newer hatch handles, I feel confident I can drill a partial hole to engage the newer handles and make them work on my old hatch.

btw, the official Lewmar replacement handle kits I bought from Defender contain two different depth external handles, as well as two notched and un-notched internal parts. As long as I can drill to the correct depth and at the correct distance, I should be able to make the new locking handles work on my old hatch.
