Performance profile...
Did something interesting today - I had the dealer pull my performance
profile from the ETEC EMM just to see what it looked like and if it
matched my impression of how I use the boat.
Turns out, I was pretty close.
The max engine RPM on the engine is 5308.
Time at differing RPMs.
0-500 - 20.2%
500-1000 - 26.0%
1000-1500 - 14.2%
1500-2000 - 4.8%
2000-2500 - 1.7%
2500-3000 - 1.4%
3000-3500 - 3.8%
3500-4000 - 21.2%
4000-4500 - 3.9%
4500-5000 - 2.1%
5000-5500 - .9%
I can narrow that down a little - 500-1000 rpm is trolling speed which
is about 650 rpm - dead idle is 500 rpm.
1000-1500 rpm is actually time at 1200 rpm - time getting away from
the ramp, no wake zones, launch and recovery.
3500 - 4000 rpm is cruise - depending on wate conditions - 32/35 mph.
The rest is fairly transitory time and the occasional full throttle
run.
Comparing my fuel flow gage to the RPM chart, it turns out that the
500-1000 rpm scale doesn't even register - which means - well I don't
know that that means because it's supposedly accurate to .2 gph.
Averaging the fuel flow across the rpm band pretty much matched my
jack lef observations - I was quite pleased.
If you guys have EMM engine control, have 'em pull your profile - it's
pretty interesting.
