I have a 2009 DF250. I was told the hours are suppose to be 10% of the tachometer reading when first turned on. My DF250 tach stays at zero. Any suggestions? I believe the engine has about 230 hours of operation.

Operating Hour Indication System DescriptionOriginally posted by jnormandin View Post

When the ignition switch is initially turned “ON” (from “OFF”), the ECM tests the caution system by turning on all four
lamps in the monitor-tachometer and sounding the caution buzzer for an initial two seconds.
For the next three seconds, the ECM indicates the total operating hours, using a combination of the tachometer needle
and “REV-LIMIT” lamp flash.
NOTE
The total operating hours displayed are those of the actual engine operation, not the ignition switch
“ON” time.

*: One lamp flash corresponds to 500 hours.
The chart didn't cut and paste as neat as I would have liked. Your tack should jump to 2300RPM to indicate 230 hours. Yours is not so I would suspect a problem with the communication between the tack and the ECM. -
are you close to a dealer?
dealers have a software program the will read all the parameters of your engine
with any error codes it may have thrown
the boat didn’t come with an hour meter?
