FAQ: Lewmar Ports
We've got a leaky Lewmar portlight. Has anyone fixed
this? Pointers? Parts & source?
I had leaking Lewmar portlights when our boat (#617 -
1988) came up from California to BC in 1993. What I found was water
leaking out of small 5 mm tapped holes near the
bottom of the frames. These holes seemed to allow water from the hollow
frames to drain into the boat. I seem to remember the holes
are to allow extra fittings to be attached. After studying the source of
the leak I could only conclude that it was getting into the hollow frames
at the two plastic connections between the upper and lower parts of the
frame. My solution was to install 5 mm threaded grub screws after covering
the threads with silicon sealant. This reduced the problem substantially.
Over the next year or so the frames seemed to tighten up and leakage
hasn't been a real problem since. You can also get leakage from around the
window seals due to dirt trapped between the seals and the Plexiglas
windows. Gentle cleaning to remove the dirt will deal with that problem
