You can always put an hour meter on it, but its not necessary. Now if you want to keep track of hours, I suggest you contact Don Weed at European Marine in SC for a MercMonitor to add to your boat. There are various levels you can get but I have two version 2's that keeps track of hours (one for pontoon boat and one for bass boat). For your motor you can also add digital sensors for trim and other smartcraft gauges. MercMonitor does the job of the tach and if you hook up the NEMA connection to a compatible GPS, you can get speed display as well as other readouts.

Take your time during break-in and learn your boat. I bet a number of people get tired of me saying this, but in long run you will be a very happy person. Congratulations on the new boat.
