Yeah, they had repaired wiring behind the throttle/shift assembly, replaced the ereverse module, replaced one of the batteries (2nd day we had the boat), reflashed the software on both engines & replaced the Medallion display module.
In each case, it worked after their repairs only to return at a later time. Personally, I think there is a design flaw from the factory. There is no way this thing should be that sensitive to low battery voltage like many people report. More importantly, what do many people do with their boats? They head to a sandbar or other favorite spot for several hours and play their music which tends to draw down the battery somewhat, not enough to prevent the engines from turning over, but apparently enough to flip out the ereverse module, which then overrides the engine throttle and forces you to limp back home. It is way more than frustrating. While the VRX is an absolute joy to drive when it is working correctly, its unreliable because of all the sensors and computer glitches., like ereverse.
Ohh, did I mention that I just dropped it off at the dealer today for another such ereverse error? Fault Codes C2161, C2101, and C2102 upon first try to start after being winterized by the dealer. Its also tripping the breaker.... been there done that before. Again, I don't blame the dealer...I believe the blame lies squarely with Chapparal and Rotax. It was a good idea in concept but poorly executed/implemented.
I have also had several other computer related issues since day 1 which prevented the boat from starting or turning over. One such issue was caused because the two engines had a conflict with a security code which prevented them from communicating with the Medallion. Why in Gods name would they inject a security code which invalidates the engine's ability to communicate with the master console? Is there a problem with customers arbitrarily changing their engines with black market versions? Of course, I am being facetious, but my point is that they went off the deep end with sensors and computer controls which inhibit the reliability of the boat.
Anyway, thanks for listening.
