Why do boats break?

I realize that boats use Chevy, Ford, Dodge (Ilmor) engines, but boats themselves are built by tiny companies in comparison to cars. What do you suppose the price and reliability of boats would be if Honda, Toyota, Ford, etc, built boats? I suppose maint and breakage would be decreased dramatically. Just imagine the engineering budget Toyota would have for drives. F1 cars run at constant super high RPM's with big hp and small cu's and they do not break nearly as often as the high hp race boats. Just my 2 rupes.
Most boats are pretty reliable....high performance boats, just by the sheer nature of what they do (go fast) is a recipe for broken parts. Especially when they are run in big water. The physics of pushing something that big and heavy, at 80+ mph through the water is enormous and requires constant attention to the mechanicals and frequent service intervals. Kind of like how top fuel dragsters basically rebuild the motor after every 1/4 mie pass.
You gotta pay to play.

"You gotta pay to play" - a mechanic once said that to me after I was shocked at how much it took to replace something simple.
Anyways, think about it this way, if you were in the water most your life, I'm sure you would break much faster than being on dry-land all the time.
Totally unrelated but watch the movie waterworld to get a grasp of global warming to the max and being on a boat ALL day.

Torque and shock loading kills stern drives. Put an F1 car tranny in a boat and be lucky to get on plane first try but I doubt it.
There are drives that don't break (Arneson, Twin Disc, etc). A boat is one GIANT compromise. It operates in an abusive environment right out of the gate. However...
There is nothing I hate or love more.

OK, so I just ordered 2 GM marine 502 longblocks (factory) from Derebery performance. They are new,factory GM built units. Do I need to do a teardown and tech inspection (verify proper clearances) Although these are supposedly marine standard engines, they dont have inconel ex valves. I thought that was one of the standards on marine engines. Any advice?
