Not to rain on your parade, but...
We have 3 of the Viking 6 seaters at work, used hard daily on right-of-way and well pad jobs. One, about a year old, with 1500 miles, is down for the count. Hole in the motor case, I speculate that something inside backed off/got loose and wore the hole from the inside to out, no way its damage by operation/impact/knocked in. Motor is currently out and at the dealer for repair.
I like mine,have about 250 miles on it.My third new Yamaha.I put 4,000 miles in
ten years on my Rhino with no problems.I went with 27" tires,bumpers,half windshield,fender skirts and front rack.
No rain here as that 700 single is tried and true, must have been a fluke...
