Question about Mercury Racing motors?

[FormulaZR]

I guess if GN7 didn't build it or doesn't approve of it, it isn't worth a nickel. I can tell you this GN7, there are thousands of Merc motors out there that run flawless and are making their owners happy campers. That's what it all about isn't it? What they paid for it is their business right? Just a little food for thought sir. There are other schools of thought out there.

They should run flawlessly. A 523 CID engine making 520-540 horsepower really isn't working very hard.

People who buy mercs do it because they don't know better. The are the bandwagon people of the boating industry. Merc makes a nice pretty blingy motor, to be sure. But I wonder, all things being equal, how much more did you pay for that blue motor with a million sensors in it vs. a shop built equivalent?

Yeah think?
Nor are they spinning very fast, which explains the low HP per cubic inch. My shop van spins as many RPM as a Merc. I understand why. They pretty much all do regardless who the builder is.
I don't really have a bitch with Merc. I don't own anything they make and not sure I ever will. I understand pretty much having to use their drive, they have the market cornered there. Kudos to them, and they did infact engineer it and make it work. Again, for a price.
They didn't however design a single component, nor manufacture virtually anything inside the engines.

What I find interesting is, you can go on Teague's site, and see almost every part he uses to build an engine, who makes it and see the price he sells the parts for. I can tell you, the prices he sells engine parts for is as good as most speed shops. and better one a lot of stuff. So you can sit down with a calculator and see just how much he is charging to assemble those parts into a running engine. You can make an educated decision if you think its worth the price he is asking. And I can tell you, the stuff he is using is some of the best parts out there. Some is the same stuff Merc uses, others are BETTER! MUCH BETTER.
Yet people will GLADLY pay almost twice for something less because it's a Merc. I have a hard time wrapping my head around that. I'm not that easily swayed.

People lay out huge cash for something, and have no idea whats in it, or who made it.
I have no doubt Grads thinks Merc makes it all and he is not alone. I use to be stunned by the number of people that have Mercs and believe that they designed and build the entire engine like GM and Ford do. I stopped being amazed by huge population of boat owners decades ago.
