Two of the 3 previous boats I have owned were demo boats and I guarantee they didn't follow the break in at the dealer and I've never had a single issue.

You telling me when Parker Payne or Sean Silveria get a new boat from Supra they are doing a 10-hour break in...No f'ing chance, they are loading them down with full ballast and an extra 1000-1500lbs of lead that day and surfing the s--t out of them.
