Warranties are mostly about showing up. You'll be required to show up some place for repairs
. It takes a lot longer than you think so read the fine print. It's an insurance
policy against a bad survey
. I'm sure it has huge limitations. The broker collects on the sale
of the warranty too. Used boats ALWAYS have problem - later. New boats are assured to have problems too. They have a factory warranty and they dog you to death collecting.
Personally, no one works on my boat that I don't know by reputation. Don't allow strangers to work on your boat unless it's just the only way. Buying
a warranty means they can send any fool they want. It's fine for your lawn mower.
