Howdy, second time out on new to me, 2013 Mojo, and she went into limp mode and check engine light. Got the code from a local mechanic but he said it's not clearly defined and may need dealer. It's a SPN 91 code to do with throttle control. Something to do with voltage on ride by wire. Anyone had experience with this or a resource to research?

The only time I've ever had this happen on my 2013 Mojo is when I had a battery nearly dead. I turned off the boat, flipped the battery switch, fired it back up and all is well. This happened when it sat at the dealer for a while and I took it out when I picked it up and also when my batteries had started to fail. Worth a shot, just make sure next time you run it that the batteries are all charged up.

For clarity, when I said "flipped the batter switch," I meant I flipped from battery 1 to battery 2 for instance and not just on/off.
