If you need to know the number of hours your Honda outboard engine has run, there are a couple ways to find out. One way is to check the maintenance records that came with your boat. These will typically have an entry for every time the engine was serviced, and will include the date and number of hours on the engine at that time. Another way to find out is to look at the hour meter on the engine itself. This is usually located near the ignition switch or key, and will have a running tally of how many hours the engine has been used.
