Yep that is correct,

That is ABSOLUTELY false. I know this for fact. The 496 will only register hours in the ECU if the engine is actually running, not if the key is on. Both of the 496 boats that I've owned have had more hours on the helm hour-meter than the engine, from sitting with the key(s) on.

What part of Canada? Maybe call Double R. Good people.

I stand corrected.

Sorry to post incorrect info.

Don't forget, with engine hour scans, as I understand it, you can have the scan reset back to zero for the scan of rev range usage but the total hours cannot be reset. (This applies to Verados and I assume it also applies to inboards).

When I bought my current boat, the total hours on the engines were all about 210 but the break down of rev ranges only totaled 108 hours. Took me a while to figure out why.

Reasons for resetting the rev range settings might be when you acquire a new to you boat and want to keep track of your usage, maybe change of boating habits like lots of poker runs and no slow cruising, possibly after a rebuild or major work.

Good luck.

Just to illustrate my confusing post (above), total run time 213 hours but if you total the individual time readings, it's only about 107 hours. I was told the scan was reset at some point. I have the scans for all three engines and they're all about the same.

N.B. This is for Verados, I assume inboards work the same way.

A 496 actually has PCM which is the engine's computer control system. Only a few people in the country can even retune them.
I would say the engine scanned hours are legit.

honestly ,i am a little confused.so if the scan that was sent to me is truly for this boat,the scan hours are most likely correct and the gauge hours are inaccurate?

It's surprising how those idling hours add up. My 525 has 386 hours; 161 below 750 rpm!
