We have a 2008 20v and have problems with the power dropping off then surging repeatedly, while using the speedset. This happens with the throttle wide open in the middle of pulling a wakeboarder. I've double checked the throttle position to make sure it wide open. The speed will drop off significantly, like down from 16 to 5 mph then surge to 10, back to 8, surge to 14 or so, for example and then finally take off and maintain the set speed again. The ECM was not replaced but the software was reloaded and the problem still persists. Should the ECM have been replaced? The problem only happens about 1 out of every 3 trips to the lake and it might happen only once or twice during that one trip when it does happen. Anyone else experience this problem or have any ideas what might be causing this? Thanks in advance for your help.

It would be worth taking a look at the paddle wheel to make sure it is spinning freely. Do you keep the boat on a lift?Mikes Liquid Audio: Knowledge Experience Customer Service you can trust-KICKER WetSounds ACME props FlyHigh Custom Ballast Clarion LiquidLumens LEDs Roswell Wave Deflector And More

Originally posted by wannab0133 View PostI just bought a 2007 20V and I have only used it on Bever Lake in NWAR and I am having the same issues with speedset. Im sure the lake is a coincidence, but I guess I need to look at my paddle wheel too. Does it happen to you when not pulling a skier?

I have same issues and the ECM typically needs to be flashed. Unfortunately my ECM has to be sent to MP so we are waiting until season is over.

Good luck on getting it fixed.
