I always pull the prop every year, usually hafta clean out some fishing line. Always wonder when I will see the flo torque hub start to fail. Good catch.
I give my trailers a good going over every year, repack bearings, usually fix lights. I look at the trailers everytime I launch once the boat is off. I also check tire pressures everytime I tow. I have still had surprise issues.
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.
