I have owned a few Seadoo's and Honda PWCs.
The Yamaha engines are 4 stroke.  I live in north Texas and will not be in water less than 10 feet.
Supposedly, these boats require no winterizing, although I do plan to put a small bilge heater in.  Oil filters, oil cap and grease zerts are all easy to get to.  No outdrive to fuss with.   I'll be keeping it on a lift, so no bottom paint expense.
Fewer moving parts / systems than my 248.  Therefore, less maintenance overall. 
Plus, it's brand new.  So, the "unknown" is not there.

I'm not quite sure where you got this notion that you'll have less maintenance though.  Have you ever owned a two stroke jet ski????  Now imagine owning two.  You're a brave, brave man.  Twin engine jet boats are maintenance nightmares and keep mechanic wallets fat.  Start or run that thing in under 2 feet of water under the intakes and you've just bought yourself two new impellers that cost $500+ each.  If you live in an area with a bunch of weeds, you'll be under the boat with a scuba mask every day pulling them out, access hatch or not.
