hour meter

Ok brats help me out, does anyone know if a hour meter records straight time run or is the time recorded varied with rpms? Or better stated does the hour meter show more hours at full throttle then at idle?

Thanks for your input,

Dan

On our Honda twin forty's with Honda gauges and hour meters the hour meters run off the ignition key. When the key is on the hour meter is counting time whether the engine is running or not. Found this out when I accidentally left the ignition key on and found I had run up an extra 5 hours on the starboard engine.

Ditto....simple device clicking time the moment it has DC juice.

If a new Honda hour meter is installed for a Honda engine that already has,say, 200 hours on it, will the meter show zero or 200?

Tortuga,

If you want to run that hour meter back....find yourself a old time used car dealer....they will know how to do it.

The Honda digital gauges only record time when the motor is running, not just when the key is turned on.
General Motors vehicles consider other operating parameters when telling you when to change the oil, but that's not the case with outboards.

I have 87 hours worth of proof that the Honda BF90 hobbs meter runs when the ignition is left in the ON position and not just when the motor is running.

I lost a long post responding to this, but here's the short version:

I think the old motors just had an electric clock that ran when the key was on.

The new EFI models have total control computers on board, just like cars, that record actual hours running (plus all parameters, sensors, error codes, etc.), and can be downloaded to another computer or sensor set.

Mine records hours run at each rpm group range (in 500 rpm increments) on my 2005 Yamaha 90 EFI model. (Tells the Technician whether you've been naughty or nice!)

Fun to read the printouts!

Interesting information. It would seem that there could be any number of ways that time is recorded depending on what type of unit you have. I would think that the best way to measure use would be to have a variable speed setup, it would seem that high rpms and low idle rpms need to be accounted for.
Thanks for help.

Dan.

If you have the analog type hour meter (I have a 2005 25) you can reset the hour meter to zero by jumping across two of the four contacts on the back of the meter. The problem is I can't remember which two. Les would know. I once left the key on and ran the meters up. I reset and then ran them back to where they where supposed to be.
