How bad is swamping your bike?

Ok … so I have been having a whole lot of bad luck with my snorkel kit.. so I am curious about how bad water is to the engine..

I will explain what I have done..

First time, I swamped the bike, it was in a lake, no snorkels… stalled in the water… towed it back and changed the oil 9 times…

Second time, with new snorkel kit, it stalled , but not really under water when it stalled, just lost power then conked.
Was able to start it up after a few tries
didn’t want to stay running, but I was able to drive it back to my place. about 200 feet away.. Did 6 oil changes immediately.

Third time, she only stuttered a bit but had no power loss while actually in the water, drove around in another circle and it stuttered a bit more. checked and milky oil. Towed it back and did 7 oil changes right away..

so… that being said.. how bad was this for the engine..
no problem starting the bike afterwards.

I want to test it again, but I am just afraid that I am doing more damage to the engine…
its a 2011 with abour 3500 KMS on it..
