Supercharger went underwater

[vegaschef364]

Is there a way to tell if I need to open up the sc after my seadoo went under, was under for about 6 hours total but was only nose bobbing for 30 min or so, the rest of the time it was being held halfway out of the water by ropes. The compartment was completely flooded for most of the time. I've gone through all the steps, drained it, removed all the water, changed oil. My question though is do I have to open the sc? I just had the sc rebuild done the day before, I only have a few days left with it this summer before we have to go home and I'm hoping to avoid opening it up to replace anything now, If it can be run for a week and then opened up would be great. But if I have to open it I will. When I pulled it maybe a Tbs. of watery oil came out, and this is what the outside looks like. Can you tell from the outside if it has to be opened up?

Thats out of the service manual for water flooded engine. The service manuals were written for dealer use so they are going to be super cautious. They are worried about water in the bearings. They probably called the bearing manufacturer and asked them and they said replace them.

Would that water get evaporated in the boil out procedure?

Probably, but you're running it with water/oil in the bearings and that's not going to be good for the bearings. Supercharger RPM's can reach 100,000 and if the bearings go it's usually an engine rebuild. Needle and shaft bearings are less than $100, its not a full rebuild.
