In all honesty, Id say that and HD-25 or TD-20 is not really a "desirerable" motor, and it probably doesn’t get more common than those.
I have a TD and a TN that I use each year at our Mystic Seaport meet and neither of them have seen any ill effects from use in Salt. Okay, I wouldn’t recommend it for a Ruddertwin, Clark Troller or a rare and valuable antique/classic like a Amphion, Cross Radial or Amarc. But the HD is a really common motor and Johnson did a pretty good job with their corrosion protection for that time. Actually, an HD or TD that had the L/U fasteners preped by a dip in Permatex or another silicone sealer, would probably hold up pretty well even under relatively long term salt exposure. It may even hold up better than many of the new motors do! I have a "dump find" 1965 Johnson CD-22 6hp that is used as a trolling motor on my Mako 19 that’s pretty much only seen use in salt since it was new in 1965. Properly prepped, waxed each year and washed off after use, it’s fine and still even sports 95% original paint!

Art, thank you for the detailed response. It is exactly what I needed to hear.
Thanks to all, James
