Engine Codes - 2017 Moomba Mojo
A question for the group. Our 2017 Mojo has been throwing engine codes since we've taken delivery. In fact, it through the codes on the first test drive with the dealer!
Thus far, we've had to have the codes reset three time . after the dealer test drive, at the 20 hr service (lights came on immediately, but boat runs fine), immediately after the 20hr service, and finally about 6 hrs after the last time it was reset.
Obviously, resetting and clearing the codes isn't working. Can anyone tell me what these codes mean? It throws the same 4 every time:
DTC 134: EG01 open / lazy
DTC 134: EG02 open / lazy
DTC 8915: UEGO pump cell slow to warm up
The last one simply says 'Engine' with no code description given.
These problems, along with crooked Moomba script on the rear seat, multiple LEDS not working from the factory (Moomba LEDS on the tower and one of the front LED bars is very dim), and last night the Wakeplate motor would not turn off (a new one!) are really making it hard to simply enjoy the boat.
Any one else experiencing engine codes and quality control issues on their new boats?2017 Mojo Surf Edition

I get those intermittently as well. It's the ECU not seeing the O2 sensors warm up quick enough. Not a big deal, but it is annoying nonetheless. I think SC needs to adjust something in the ECU programming with Indmar's help.

I work on cars in my spare time, so I knew they were O2/emissions related. The odd thing is, these came on last night after about 40 minutes on the water. Is there any way to clear, or am I stuck with the engine light on until the dealer clears codes?

Happens on MBs a lot (O2 sensor) Indmar said it was to much idling (wtf?)
Turn battery switch off then on always fixed it, well at least for MB. I haven't thrown any of those codes with my Raptor

Engine Codes - 2017 Moomba Mojo
I had codes on my mojo from the get go too, but my dealer knew that there was a service bulletin out on it and they needed to install different sensors. They didnt have them at the time of boat delivery but told me not to worry about it and that they would switch them out at the 20 hour service, which they did. They also found a second bulletin and swapped some additional sensors out at the 20 hr service. Have you had this done already? Surely your dealer should know about this. From your description, your dealer doesn't sound like they are the best. Who is it?

Makes no sense. If you turn all batteries to off it cut power to ECU and codes should clear. Just like pulling the negative off you battery in a car clears the Check Engine Light.
