From the link: Unique semi-dry sump oil system lowers the crankshaft in the engine, eliminates the need for scavenging pumps, and if the craft is capsized the oil stays in the sump instead of flooding the crankcase - Kawasaki's patented oil separator provides fail-safe venting for the crankcase and prevents oil from flowing into the intake tract if the craft is capsized So where did the water enter??
