New craz misfire codes

[Dan]

Getting misfire codes on 1,5, and 6 cylinder. Some codes are even saying damaging misfire. I have listen to the motor and can feel it running just fine. No hiccups or anything. Was wondering if anyone else is getting these codes?

I would imagine, it would be difficult to feel a misfire on the water. Unless it's a dead hole.

One thing that you could check is to make sure your spark plug wires aren't being crushed by the engine side panels when the rear water ballast bags are full. I installed some wake makers panel stiffeners on my engine side panels to help reduce the amount of flex. They would bend and hit the engine valve covers before I added the stiffeners. This is just idea of something to check. My boat never had a misfire problem.

I am getting the code during these few hours I have put on the boat with out filling any ballast. I was wondering if the fuel I used could be causing it. I used 91oct with no ethanol. Dealer said he had a mondo do it the weekend before and that SC told him some motors were doing that during break in. I have payed close attention to the oil pressure and motor temp. Both were in the acceptable range.

Why would the fuel be causing it? Isn't the raptor minimum 89 octane?

Just looking at everything and anything that could cause it.

Mine threw a CEL and O2 sensor codes on Friday....first time taking it in the water. My dealer cleared the codes, put it in the tank and everything supposedly ran fine. I'm a little disconcerted at what is seemingly many new '17s throwing codes right out of the gate...these toys are too expensive for this kind of BS.

I have been told by the dealer that the Raptors do not like prolonged idle. It will throw o2 codes. Apparently they build up moisture at idol.
