GTI SE130 resonator melted!

[sbaker217]

My Granddaughter was using my NEW (10hours) GTI SE130 when the intake was clogged by weeds. She got a high exhaust temp message but before she could take appropriate action the ski started to take on water and rapidly started to sink.
Thank God for three young people in a small boat that towed her back to the boat ramp.
Upon lifting the ski from the water, we found that the plastic resonator had a two inch hole in the inlet. This was the cause of the ski taking on water.
We got the ski home and found that the engine had ingested water. We got the water out of the cylinders and I have changed the oil twice.
I still have three fault codes and an indicated ECM fault.
Has this thing happened to others out there and what do I do now? I can't believe that Sea Doo would put plastic components where they could do so much damage.
Looking for advice
This has turned my whole Sea Doo experience quite sour!:banghead:

Sorry to hear about the trouble. These engines have 2 separate cooling systems, a closed loop system with antifreeze for the engine and a raw water system for the exhaust cooling. The raw water exhaust cooling get water and pressure from the jet pump. When the jet pump gets clogged and cavitates (which is what you described happened when it was clogged with weeds) the exhaust system is no longer supplied with cooling water and can become hot and start melting very quickly as is what happened to your ski.

The hole in your exhaust most definitely was cased by this overheated exhaust, once the system is breached sea water can freely flow into the hull and it will start sinking and flood everything. The first problem with the overheated exhaust caused all your subsequent problems. Likely that electrical components either got melted or flooded with water which is why you now have electrical problems. All marine engines (boats, pwc's, etc.) have raw water cooling for the exhaust not just seadoo's. This kind of thing could happen to any boat if the exhaust cooling system gets blocked up. Why they make exhaust components out of things like plastic or rubber that can melt is up for debate, but most if not all manufacturers do it. Some people replace the exhaust components with metal free flow devices but usually as a performance upgrade. Need to be careful how and where you ride as with any marine craft.

Need to start going through every connector and engine component to get the water out and everything dried to prevent further corrosion. Also try to get that engine running and up to temperature to evaporate all the water drops still left in and around the engine. If you have any other specific questions about how to get everything back running again post back or search the forum for other threads and info, other folks have gone through this unfortunate experience as well.

Same boat

Well at least your unit had 10+ hours on it! I got my 2 machines to the lake and had 1 hour on one of them before it sank! it took 10 seconds from the time the flash of exhaust temp high coming on, switching to "Limp mode" and then back to normal (When the exhaust temp sensor melted)

our boat sank to the bottom of the lake and when we got it to shore we see the resonator had blown a hole, another exhaust hose (That ports on the actual can) had pulled right off the port rad hose still intact.

In addition the wear ring straps that hold it in place had blown off and had been sitting in the bottom of the hull

We pulled the boat to shore and when on the trailer checked to see if we had brought anything into the jet. (Nothing) even the dealer said they found nothing in the jet

BRP said that they would not honour warranty and insisted it was because I MUST have had the jet plugged and I would not be a manufacturers defect....



Took me 3 weeks of back and forth to tell them to simply fix it ($1400 CDN)

I feel your frustration and feel that the engine should have shut down to prevent the boat from sinking! poor design in my opinion
