OK, let's try another.

What part in Mercruiser outdrives required them to pay royalties to
Volvo Penta?

(Getting my ideas from a great book called "The Iron Fist".)

It's been a long time since I read that book, but my recollection is from
earlier days with OMC. I believe the dual u-joint drive shaft was the item
that required the royalties. OMC stern-drives had to use the "ball-gear"
setup to get around that patent. Back in the '30s, OMC had a stern drive
setup used to power barges.
