...little place for them here, eh?

Anyway, here's a snap of Yo Ho's business end. I'm waiting for the
shrinkwrap guy to show up this week. Wrapping the exhaust after the
motor drains is part of the winterizing process. I've got to spend a few
minutes removing the rust from the prop and repainting it. One of these
days I'll find a prop paint that actually stays on the blade tips. *:)

Why paint a stainless prop? Surface rust on 304 SS is normal ... if
you don't boat a lot. It really isn't hurting anything. If I am out of
town for a few weeks and not boating I see a little on mine. It buffs
right off after an hour or so of running

Yeah, it does come right off while running. I never gave it much
thought. But I'll still clean it off and coat the prop before the
shrinkwrapper arrives.

Actually, coating stainless promotes rust. Stainless loses it's rust
resistant properties when deprived of oxygen.

Hehe.. quit trying to punk harry. Stainless steel is stainless mainly
because of its chromium content. When exposed to air (oxygen), it
forms an invisible, but impervious, layer of chromium oxide which
protects the steel underneath.

Coating the stainless with paint will not cause it to rust. It would,
in fact, protect it. When the paint wears away, the layer of chromium
oxide continues to protect it.

That prop is just made of a type of stainless that isn't so
"stainless". It can corrode, or "rust".
