View Full Version : Engine hours/usage

When my boat was in the shop, my mechanic hooked it up to the computer to do some diagnostics. What I didn't know is that the computer keeps track of the engine's running history.

Out of 148 hours, my boat was either off (but key on) or at idle for 101 hours, or 68% of the time.

The boat was at slalom speeds (3000 - 4000 rpm) for only 20 hours, or 13% of its running time. Other speed ranges were used even less.

I knew I idled alot between ski runs, but never would have expected that much. Of course, I just bought the boat recently so those numbers were mainly controlled by the previous owner.

I just thought this was interesting and wondered if anybody else had similar data for comparison.

The hour meter runs with the Key on only? What about Acc. on only?????

2007 Manual say hours only tick when RPMs above 300... so key right, engine off, hours shouldn't count if this is true.

He didn't say hour meter he said from computer. Shep what's on the hour meter compared to the 148 from the computer?

Pretty cool that I ran accross this thread. Just last night I bought and brought home a 1997 Prostar 190 with 124 hours on the meter. The computer diagnostics verified that the engine had only ran for 102 hours. Hard to believe an average of 10 hours a year but that is what the computer verified! SUPER clean boat and engine! Can't wait for the weekend!

I didn't know that. The readout just gave the hours for "0 - 1000 rpm" so I assumed it counted when the key was on but not running (0 rpm). I could be wrong though.

The hour meter is only showing around 137 hours. I was wondering about that too. :confused:

The shop I took it to was FL Inboards. He's not a MC dealer - actually its a SN shop but he'll work on anything. Sells used MCs and SNs.

I found on mine that 82% of 117 hrs. were idle/key on hrs. The rest were at speeds of 4000+ rpms.

I am pretty sure this is correct. I know the the guy really well that I bought the boat from and he bought it new at Texas MC.

Most of my boats life before me, was beer cooler transport across the cumberland river. Then sat with the radio playing most of the time. So the stereo has more hrs. than anything.

4000+ rpm? Is that barefooting speed? I turn around 3300 rpm at 34 mph slalom speed.

Do you think the computer counts when you have the key turned left?

I don't know. I wouldn't think so, but that might explain why my hour meter reads less than the computer total.

Could you remind me what prop you have?

On a 197? Wow, seems aggressive, but hey it works. Do you like the overall performance?

My dealer told me that the new 2007 will not count hours until the RPM's climb where as the older boats they would still count hours as soon as the key is turned on or off regardless if the boat is running.

The prop works great with the powerslot and LQ9. Someone lent me a smaller prop earlier this week - something like a 13.7x15.5 - and I was way over-revving with that prop. At 34 mph my engine had to turn 4400 rpm, vs. 3300 with the 14x20. I quickly changed back to my original prop, but it needs some repair work.

Forgot you had the LQ9...Makes more sense now. Thanks.

Makes sense to me. The extra hours are probably testing at MC, dealer demos, replaced or reset the MDC, etc............

The only true way to know how many hours are on a boat is to check the engine computer. Too many ways to reset or replace the MDC box which logs the hour meter.
