    Default Bad catalytic converter?

    Well fellow forum members, a few days in on my 16 SA550 and we have an issue. Engine started bogging down at 3000RPM and then would rev back and forth between 2500-3000 but never above. Got the attached error message (eventually) and took the boat into local dealer. Turns out the catalytic converter is shot and some localized heat damage to some hoses (melted holes). They're doing more diagnosis, working with Supra and Indmar on root cause. Looks like I am out of commission for a bit :-/. 120 hours on the boat. It was used for training and the Local DFW area Pro Wake Tour. I'll keep you all in the loop on the prognosis.

    Anyone else had issues with the cat on newer Supras or Moomba's?

    Damn I'm sorry man. That's rediculous for something of that nature so soon or at all for the price of SA550. Hope they get it figured out soon.

    This isn't a Supra Moomba issue, this is a Raptor engine issue. Please don't confuse that.

    This engine could have gone into any boat and had this issue.

    Doesn't matter the price of the boat, when it's an engine issue.

    There is always a small % of parts that go bad ahs that's what it sounds like here, you got the short stick on the quality of that part.

    I'm well aware of that. I also know SC and Indmar will take care of it, just a bummer to deal with during peak season.

    I agree with both of you and understand the distinction between it being a Supra issue and a Indmar issue. According to the dealer, both Indmar and Supra are at the table to help figure this out. They are rushing parts (there was literally 1 cat available and they're rush painting and shipping it to minimize downtime). It could be as simple as that small percent bad draw of parts. I am pushing all parties, though, for a root cause. It is frustrating to take a new boat out for the first time with friends and family and be left crippled on the far side of the lake.

    Thanks for your insight and your sentiment guys. I'm confident they will do right and fix this.

    The cat and supporting parts should arrive tomorrow and I should be back in business this weekend! Still awaiting root cause but use of my new boat is also great.

    Woody929, they have been great. They are clearly motivated to get us back up and running as soon as possible.

    Iceman, SS is Slalom Shop in Lewisville, TX. They are the local Supra/Moomba dealer.
