CanDoo engine hour discrepancy

[JPass]

So we just purchased a 2012 Seadoo Challenger 210SE last week. We traded in our beloved '92 Ski Nautique with 1820 hours on her. She ran like a champ and the motor was almost new compression wise (155psi vs 160 for a fresh motor).

My buddy came by and we hooked up the boat to his PC and ran the CanDoo software on the boat to check it out and see the history and how the boat was run, etc.

The one thing we couldn't figure out was the software showed the hours on each motor at 108 hours and 107.8 each, yet the reading on the dash cluster says 113 each. I highly doubt the motors were replaced at 5 hours, so we're not sure where the discrepancy is coming from???? Maybe new computer 5 hours into running them originally?

Anyone else ever experience this?

I don't think those gauges on our Sea-Doo's are accurate. I know that the speedometer is off by as much as 15% (compared to my GPS) and the tach is also not accurate. When idling out to the channel the tach bounces around from 1780/1840 and the hum of the engine doesn't change. That is the only explanation I have.

The hour meter is a digital display. It's not an analog gauge like our old boat.

One or the other is simply not accurate and reads slower or faster.

some one else not long ago had a similar question, maybe the cluster is counting the time power is on? therefore over time this accumulates to a few hrs.
since the candoo reads from the ecu, i would believe that first. but ask your buddy to get on the candoo forum and ask that question to the developers of candoo.

I thought that too, but I've never seen a boat that counts hours with just the key in the on position. That wouldn't make sense. If you accidentally left your key on for a day, then you'd have 24 extra hours on the meter that didn't accurately reflect the number of hours on the motor. Every hour meter I have ever seen only counted hours when the motor was running.

Definitely strange.
