Hi guy's,I bought a 75 Evinrude 15hp and this was attached to the power head, I've never seen anything like this,just curious if anyone knows what it is and what it's function is ? I've taken it off ,it was attached to a 4 or 5 pin connector,just curious that's all

Used to sound an alarm if motor should overheat.----Custom installation.-----Best to install a new impeller every 5 years.

So it's not a factory/OMC part I'm assuming?

Just a temperature switch. looks like it is set to close the circuit at 150 degrees. Somebody came up with a custom temp alarm is my guess. I like the ingenuity.
