Interior wood

[Knotty]

I have a 1988 37’ Double Cabin with of course wood on the interior, doors and drawers, would this be the same teak that was used on the outside steps?

I have a full size door that was for the rear head, I removed it, but need some new steps for the outside, will it hold up if treated?

TReated how?Any wood painted or stained and covered in poly will hold up with, perhaps, annual touch up. But teak (which still needs annual loving) is the best because it's an oily wood and fends off moisture. Marinettes got exterior teak touches.

Treated teak. The question is will the teak used in the interior last as well on the exterior.?

Most interior larger pieces/paneling is veneered plywood. I would guess that head door is veneer and will fall apart outside.
Most smaller interior trim pieces are solid teak.

I used Plasteak to make new exterior steps.

I’ll have to cut into the door to find out, not very keen the the plastic stuff.

I can vouch for Plasteak. You won't regret the choice - it is easy to work with, cleans well and easily and just lasts and lasts!

Oh, the door is 72” long, 2 5/16 thick about 18” wide and it weighs good.

Pretty sure you can tell plywood by looking at the edge without making a fresh cut. All the doors on my 1972 are plywood, stained and varnished, as they should be. A thin panel of solid wood would be very likely to warp badly.

There was C teak trim all around the edge, I knocked that off to see the edge, it’s thick plywood that I’m gonna use to patch a too large of a hole that was cut into the galley counter top..
