The first tool I installed to monitor engine output while changing props was a Vac guage. It is a good performance tool for keeping an eye on the tune and the growth on the prop. Once you have tuned the engine to the boat the guage should show the same vac at the same rpm or somethung is wrong. It tells you how hard the carb. is working to feed the engine.
