Help with snorkeling….

I have a 2015 900s an was wondering if any one jas some suggestions on snorkeling it? I was thinking about trying to run strictly through the side vents so i dont have to do any cutting. My question is what all needs to be sealed and done?
Im also not looking to purposely get that deep in water but id like to have the peace of mind knowing i can. Thanks for your help in advance.
