What to consider when purchasing a used PWC (Personal Water Craft). 2 Stroke vs 4 Stroke, Costs, Etc

This is not nearly a comprehensive list of everything to be aware of when buying a PWC.
I hope it will help someone who has no experience with watercraft to be more aware of what they're getting into when they see a cheap PWC.

We will be doing more detailed videos zeroing in on specific brands and even specific models and their pros/cons as time allows.
