new 2016 3-cylinder overturn problem...

hi all...
recently i bought vx cruiser HO 2016...
i use it for rental jobs and it overturned yesterday....
i take it to the beach but it doesnt work perfect....
after that i carry it to yamaha service...
and they find a lot of oil in manifold and air filter.....
it was really awfullll !!!!!
i have been using yamaha vx 4-cylinder more than 5 years and
i had many overturning experience but after that jet ski had no problem!!!!
i ask this question from yamaha dealer they told me that yamaha change oil pump and
use wet sump oil pump instead of dry sump oil pump in new models and it has not oil tank and when your jet ski overturn oil goes to manifold and make that problem......
have you ever experienced it????

Have not experienced it, but they would be correct for a wet sump system. That would happen with any 4 stroke engine with a wet sump system.
It's just the nature of the beast.
The only thing that can be done, is not flip the ski.
