Anyone have or tried one of these. I'm thinking about picking one up to get my prop figured out on my river boat. Does anyone have one I might borrow for a weekend before I buy one?
I've installed several hundred of those. They work great. Can use on any gas motor. Wrap the sensing wire around the #1 spark plug wire, depending on how many cylinders determines how many wraps. Some of them have hour meters built in and maintenance monitors.
