I do believe a few times mine intermittently had an extended long crank time, actually it did not fire, released start button and re-cranked it then it fired. The ski had already been started within last 30 minutes before backing trailer in. In my case I was running a TBM flywheel that turned out to causing week and missing spark events @ TDC during the cranking and running. When I switched flywheels to 62t lightened my problems cleared up. The season is just starting for me, I've rode once in last 70 days which was last week and I did not notice anymore extended crank and don't remember any with the OE flywheel. To be honest i thought my extended crank was strange but I never really paid it too much concern because it always stared on the second or 3rd crank with that TBM wheel.
Overall my ski is re-starting on the water after a failed trick attempt way faster with the HX3 and OE flywheel, it's instant now! Before with the enhancer and TBM I always had To crank it for a bit before it would fire.
