We do like Evans. Never had special protection, except for the cutters for rigging
wire: Jim sprayed them with Boeshield. Jim has a (probably) 45 yr old 1/2" drive electric
. We've used it some. It used to leak oil
. Must have run out of it. We also have a cheap
B&D 3/8" drive drill motor
that was a gift to me, bottom of the line, after I was divorced, by a friend of the family
. (Thank you Keith, I really wanted to make holes!) It still works, no special care, kept in it's original cardboard box. It is not our good drill, but it still works okay.
So here's what I say, don't overthink this one. If you have a dry boat (and I-1 wasn't, but I-2 is) they'll do okay for 25 yrs. or so, anyhow.....
