Motor hours

[slammer]

1999 150 Merc EFI. Can a shop find out how many hours my motor has on it? What is considered average for this type of motor?

most motors can be hooked up to a computer and the shop can check hours and if any alarms went off. I would say just call a shop that works on mercs and they should be able to help you out.

I don't think that the older two strokes had computers in them, so I would be surprised if there was any way of reading the hours.

isn't the EFI ran off of some type of computer board on the motor so that the system knows what adjustments to make to maximize fuel economy. I guess I have only seen the newer motors that could be hooked to a computer.

I know a '97 150efi can't, and don't think the efi's have changed much, that is the 2 stroke "efi"s. But the '97's were also the last year before some type of epa change, or so I heard, that still allowed them to be hopped up and be legal. Not sure what it is, as our boat is not a speed demon so we never tried anything other than props and motor height and weight dist to gain performance... whoops, that is not for this thread though
