Well I have great news and I'm one happy customer! :D On the old site I posted some difficulties I was having with cold starts and backing the boat off the trailer. The short of it was that the boat would knock and stall initially when I would put it into reverse to back off the trailer until the boat was some what warmed up. This only happend when the motor (LTR, 330 hp, EFI/MPI) was stone cold. At normal operating temp it ran fine and would not stall.
Took it too the MC dealer a few weeks ago to see if any error codes were being thrown and none were and the dealer was somewhat at a loss. So not wanting to waste down time, I thought I would just live with it till winterization and replace some parts others have suggested or let the dealer have it longer and figure it out.
Well last week the dealer called me back and said that one thing I could try was reflashing the ECM. So I took it in and they sent the ECM to Indmar for recalibration. Let me tell you that I am one happy camper! J J J ! The boat is running better that ever. I did not have the cold start issue and now it fires right up on the first key turn. It is now idling higher at initial startup and then backs downs to 700 rpm or so after about 20 secs. When I put the boat into reverse to back off the trailer, no more knocking or stall.
Turns out that my ECM was two generations behind in the calibration. It also idles so much smoother now as well. My wife even notices a difference. One more thing that has also improved is when pulling a skier out, it would ever so slightly hesitate on engaging the throttle forward. No more of that as well. As soon as you move the throttle, it takes off. So if you're having similar problems as I had you might try recalibrating the ECM. It only cost $50 to have it recalibrated plus 1/2 hour labor. I paid a premium for shiping (three day turn around as we had a family runion this past weekend and I wanted the boat for that.)
I’m surprised that at the ECM was not re-calibrated by the MC dealer previously during routine maintenance, but since they had to send it out, I can only assume they did not have the proper equipment to do that in the service shop.
In any event, we just had a ball at our family reunion. 160 folks from all over the country and we used the boat about 10 hours a day over the weekend, with out one flaw! Just a perfect event, and thanks to MC Dealer and Indmar, it was even better. I pulled skiers, wake boarders, tubers, and the “rocket” for the little ones. Just great family fun!
