Omc part

[saltchuckmatt]

Okay, I received a whole bunch of parts when I bought a whole bunch of outboards this week or last week I can't even remember. This particular thing was in a box with an older Evinrude simplex box and other assorted parts.

Anyone know what it is?

I think it’s a sort of fume meter

combustible gas detector.

I need one of those to attach to my sons backside.

Funny, yes my friend guessed some type of fume checker.... probably down under a hatch.

maybe for an I/O or stringer to put sensor under the cowling to know when to use the blower.... although seems like you should be using the blower regardless

Racerone is right.
It is the meter from a combustible gas detector

Pretty cool really. Also came with a good old fashion amp meter.

Good stuff.
