    Engine Hours

    Came across this posting on a different forum:

    I am considering buying a boat that has a pair of f350 Yamaha motors with approx. 900 hours, 331 hrs are under 1000rpm, 301 hours are between 1000-2000 rpms, 161 hrs between 3000-4000 rpms.
    I run an older 2 stroke so I'm not up to speed with newer features included with four strokes. Does the engine record this specific hour:rpm data? If so, that's pretty sweet.

    Yes. And codes are displayed at what hour they occurred. It's interesting the total hours on ECU never seem to match what shows on the Yam dash gauges.

      Should we measure our road vehicles in hours versus miles? I am in sales. I idle in parking lots for long periods of time. So do cops....

        If outboard engines have this technology then I recon auto's could have the same.

          My 2014 GMC Sierra has an engine hours count in the ECM that will display on the dash along with other information. Most new vehicles probably have the same. Diesels I think have long been gauged on hours?

            Lots of airplanes have hour meters to record engine run time. On some, the run time will vary as a function of engine RPM. So idling around at 600 RPM won't count the same as will flying at 2600 RPM.

              Fixed it for you. You are welcome.

                This was implemented on 2 stroke HPDI's and 4 stroke EFI models. Engine hours as a function of RPM bands can be seen on YDIS.

                  I had fun recently. I got to drive a Lamborghini for a few laps on a very small road track. Top speed maybe 70. Got there very quickly with 550hp. 1st and 2nd gear only. Can't have people like me driving their cars at 180mph. Point is....what a brutal life for those cars. Jolting around in first and second gear and slamming on brakes. No matter the hours, who would want one of those things after a year or two?

                        "pablum" was just a word I tossed in to ensure that my post met the minimum character count for publication. Its what came to mind and was not offered in an attempt to editorialize my post.

                        But, you're right. I don't have the time. My battles with ethanol are likely over for the time being. Both engines running pretty darn good. The "good" engine is now the "bad" due to its very rare habit of shutting itself off for no apparent reason. The "bad" engine is now damn near perfect and justifies the original purchase price. It hasn't quit in the last 50 hours, so I am fairly confident that I fixed it. WHAT I fixed I'll never know.

                          I bought an ex cop car once. You know "It's got a cop motor, a 440-cubic-inch plant. It's got cop tires, cop suspension, cop shocks."

                          Drove it for a year. Great for having people move over from the left lane but nobody would pass you. When I went to sell it, a cop who was interested in it noticed that the hour meter was zeroed out or removed. I don't remember which. But he didn't buy it because of that.

                            I had a Police Crown Vic (take home/I was the only driver), small V8, model year 2000 until I retired in late 2006.

                            I had the oil changed as required, washed, waxed(myself), cleaned the seats monthly, engine, etc.

                            It did see a lot of idling and WOT, but was WELL taken care of.

                            I would have kept that car for myself if possible when I left. Didn't burn a drop of oil..

                            Several officers wanted that car when I left as it was about the cleanest car in the fleet. One got it a totaled it a couple months later-rear ended by a drunk...

                            Bad Luck! Being drunk and and just happening to rear end a cop....

                              440 police interceptor.....probably 7-8 mpg. It probably did have special carb and cam.....Now I remember talking to a state trooper in the 1970's. He told of having his early 70's cruiser pegged one time at over 160 mph. Scary considering bias ply tires or whatever they had on those things.
