I have a Bob’s machine shop trim on my 40 Yamaha. It’s not working and there’s a whirring sound coming from the relay. I tested with multimeter and getting 12V to the switch but only 6V going back to the trim motor. I’m guessing the relay is bad?

Next question. Should I just replace with the relay from Bobs or is there another brand that would work better?

I haven’t even had it on the boat for a year so pretty aggravating it already went out. Boat is stored under carport. Relay is mounted to side of boat. Could vibration have caused it to fail? Just trying to figure out what caused the problem to try to prevent it from happening after part is replaced.
