Satisfied TriMatrix user -- link to blog on installing them!
I did indeed purchase a whole set of these for installation on my thru-hull ports on an Irwin 43 center-cockpit sloop, which had the Gray Industries plastic ports so common from that era -- found the TriMatrix ones fit almost exactly in the existing holes (just a bit of trimming) -- they have not leaked at all, what with the sealing o-ring of silicone, rather than needing any bedding compound. NFM's all-SSTL ports seemed to be just too heavy a "look", and overkill --- besides, those do not have the silicone o-ring but rely on bedding compound (which can dry out and crack...)
for my write-up on the installation procedure, with lots of photos, See: irwinboats.com and click on the firsst article on that home-page.
Regards,
Wayne Gilham
