They must be taught this at the dealership indoctrination
Mine said the same and so did the bloke in Darwin and Bowen but after a few questions it became apparent it was possibly not common but something they needed to keep quite or FOB the customer off on due to lack of support from BRP.My Mac dealer (across the marina from the mechanic) has also taken an interest in this as well as they claim that mine is the first Etec to have this problem
Another thing I was told was that the transition from vapour to spray can cause a problem but that was at the wrong rpm range, was also told by running it consistently at 1200-2000 rpm it caused the plugs to foul (my fault again) but the mech in Darwin said they had boats in an indigenous area that did thousands of hours prohibited from doing over 1500rpm with no problems LOL
Yes they thankfully and finally put a new powerhead on mine but I still don't know what the original problem was, I have a couple of ideas but the new powerhead (2010 mod) performed well with little or any problems except at the start but after changing to the spare prop to keep the WOT rpm below 5000 rpm it ran sweetly and this suited me as this prop gives way more top speed especially unloaded and with the dinghy off we possibly did 80-100 hrs with it but mostly at about 1200-2000 rpm.
I am hoping it will be ok this year as we will be finally heading (or again) to the Kimberlies and it is not a place you want to be without or with unreliable power (good but unreliable winds and 5-10 m tides) there is sheltered spots with 800 islands but picking beaching and anchoring spots with tide currents around the islands and rocky bottoms could be hairy which besides loss of time was one of the reasons I gave it a miss last year.
If the motor plays up this year you will hear me over there without any electronic assistance trust me
