Recommended Posts

Recently purchased a 2018 23 LSV, i have read that the co2 and or manifolds are failing. I've read where you shouldn't idle very long etc.

Anyone have info on this?

Did it through  codes or how you know it is happening?


I had this happen to our '17 22VLX with the Ford 6.2 Raptor and it did throw codes.  Here is a thread I started when it happend.

Yes my boat threw a code for about 1 second that then went away but was stored in the inactive codes.  It was discovered when I was having the annual service and the tech inspected the cats - he found one pretty much gone and the other severely damaged.  Seems to be a relatively common issue and was covered under warranty.  My boat did not show any issues or performance problems at all, and I ran it for a good while until they could get the cats in stock and schedule me to bring it in - never any hiccups, and can't say that I can tell a difference once they were replaced either.

20018 LSV.  410 raptor.  My cats failed too.  Had a rattling sound.  Scared the hell out of me. But it was just a piece of metal in the exhaust from the cat.  Both replaced.  Had about 300 hrs.  I Never sit idle.
