A friend with a 419 Formula with triple 500s received 3 new drives from Mercury as a settlement I believe after he blew 19drives.
It would seem with the regular Bravo you blow the floor out of the gear and usually just replace the gear. With the XR it would seem the case blows out with the rest of drive. Most of the time the case that holds the pinion blew out.
Hopefully no one is offended.
