A simple multimeter to your ground and in my instance, thru hull fitting. in salt water an acceptable reading would be 0.4-1.6 Mine was super high at 16.This led me to check the whole grounding/bonding issue. It doesn't last forever. Checking for proper grounding is important or it will eat up your zincs and eventually metals. If you are changing zincs either on the engine or exterior with a diver at a rediculous time frame check your grounds.

The fitting I tested was just replaced 3 weeks ago when she was hauled in the Bahamas.

I also thought my grounds/bonding were good. Surprise! I'm learning as I go so technicality of words is not my strong point. I know basics on electricity and how it gets in the water and where it is more likely to occur.

It really doesn't matter what kind of boat you have, it should be checked periodically. Not a fun job.
