Question about Mercury Racing motors?

[gn7]

Good point, I forgot to consider that.



I wonder. On the outside looking in, it's sometime hard for me to understand why the Mercury engine are so expensive. On the website/sellsheet, there is very little information provided. I'd love to know the composition of the rotating assembly, cam, and intake/TB specs.

Its not Mercury as in Mercruiser that is so expensive, although even a black Mercruiser is way over priced. But the Merc "RACING" blue engines re-define rape.
The industry is not what it was. I saw it coming when Schuster started laying up Tahiti hulls as fast as the resin would set up and standing hulls on their transoms in the shop waiting for a customer to walk in. Choose your interior and engine and 4 days later you were on the water. 5500 out the door. 90% of them were crate Olds engines with a few Harman marine 427 or 454s with a oil pan change and some plumbing changes to make them work. The crate engines from GM were dirt cheap. And they sold a zillion of them to every person that wanted a boat but need instructions included when he bought a screwdriver. And it only got worse and worse.
You wanted to go 100 in 1968, you better know how to build a boat. Now, you need to know how to write a check.

I chuckle at the thought that Merc gets that kind of money for a warranty. That's all they are buying.
Once I learned what was being used in the 1350/1650 twin cam engine, it pretty much told you whats NOT in the 565 or 600, let alone the 520 and 540.

This is the crank in the 1350/1650. I assure you, its NOT a Sonny Bryant or Winberg.
I am almost certain it is a Lunati. Its most likely a "Pro" but Merc's replacement cost is $6000.00 A Lunati Pro crank is about 1700.00
A Sonny Bryant EN30B billet is less than 4000.00 LIST!! and nobody pays list!!
The rods are even worse, in that I'am pretty sure they are Lunati H beam IMPORT rods!!!
The pistons are 476 apiece, head gasket is 373 EA, and these are the "online discount" prices.

For 6000 this should look like jewelry.



This is a Sonny Bryant billet.
ANY QUESTIONS?
