Help!

[krock]

I need help with this part! My engine on the left side of this picture overheated and the part failed! I need the part number and possibly somewhere that I can purchase. Thanks in advance!

Holy..... lol that's a first for me. That's the catalytic converter. Not cheap. Some bypass... but bypassing it isn't a trivial thing since lights/sensors have to be stopped via special hacks. Alternatively, you replace the cat properly... there are very specific torque patterns, install procedures to follow otherwise it will leak. Unless you absolutly know what you're doing, you should be getting a dealer to do this.

To look up the part:

BRP Parts Catalogs

epc.brp.com

Rotax > Rotax JPS > Two letter code where 2014 is AA onward so AG for 2017 > Engine HP > Twin engine with cats starboard based on your pic.

Find the the catalytic converter diagram. (Catalyst Housing)

and before replacing it, I would ask what caused it to heat up so much that it melted. if that issue is not addressed, then it will likely happen again to the the new CAT...

Thank you so much Luc! I was running the boat at the dock in very shallow muddy water...I was trying to charge up my batteries! I think that sediment got in!

Question where can I get the part? My mechanic is a jet ski guy so I am confident that he can replace it properly. If I am on the boat and looking toward the bow it is the right housing. If I am facing the engine bay it is the left. Again thank you so much for all of your help!

Then it is starboard (right) when facing the front. I don't think there would be any difference in the parts in this case. Probably identical part numbers for both sides (but you can check that yourself in the part diagrams).

Cats don't really exist on Sea-Doos... not enough room. So you'll need to find someone who sells this. The best/easiest solution is indeed a Scarab dealer. I'm from Canada.... I know the New Orleans dealer is very popular and ship direct. I'd give them a try. But they are busy. Note that without removing the current parts, you'll be guessing what needs to be replaced. So I think your mechanic should be removing these parts to confirm what's damaged besides the housing. Nothing else? The resonator box? Follow the path of that exhaust system and check each part. If it got that hot in the cat, other parts could have been damaged/melted, especially any plastic.

You'll need to ensure it's clean of mud/sand in there and that water flows freely. For future reference, the engine should not be run in less than 3ft of water, especially idling in place. It creates a vortex underneath and sucks up everything.

I should add, if you do order from a Scarab dealer, have your boat HIN number ready. They will likely use that to look up the part to verify it fits.

Also, check with your mechanic that he knows the correct torque leves and patterns of that cat. That he has the latest info on that as well. There was a recall years ago on this specifically because of the incorrect torquing done by the manufacturer, causing leaks... and thus damaged things like O2 sensors. So this isn't a "just do it by feel" type of thing.

 

[Luc Lafreniere]

Look at that, search to the rescue! https://jetboaters.net/threads/o2-sensors-and-warranty.17727/post-538411

That link should bring you to the recall documents. Hopefully they are still up to date. But I recommend you print that and give it to your mechanic ahead of time.

The MotoMarine Rotax Catalyst Delete kit is out. This is done without any modification to your ECU or Wire Harness.

We have developed our own exhaust race plate, which allows you to relocate the O2 sensors onto the exhaust manifold without modification or drilling.

Comes with a PWC style waterbox and all of the parts you need to make it work. There are only 2 things you need to work out, as every boat is different. We can guide you with both of these.

1- The cooling line connections. We can give you a diagram of what needs to be done, and you may need to order additional hose and T Fittings in order to make it work.

2- The exhaust varies by boat to boat... so you may need to modify your existing hose in order to make it fit properly.

We've successfully deleted the Catalyst on Scarab, Chapparral, Williams Tender, Seadoo Switch.
