Why are high performance boats so expensive!

Sure the O.E. will test as you say and when another packager, if we can call them that, uses the product then the test does not have to be done again since the data has already been recorded. All of the test data will be used by engineers/builders for determining performance parameters. For example a cast internal bbc will have a marine limit of 4800rpm but a forged internal engine will have a higher rpm limit based on the material strength of the components used. If a dimple rod forged crank motor built for a Vette is tested for the data and that same set up is put in a boat then the comparisons are the same. When the marine world uses that block or heads but changes everything else inside they already have the test data from the tests you mentioned so testing over again is redundant. Marine is going to test the areas they don't have data for but that doesn't mean the testing of either one is better or that marine does not test. Rather it is different for the needs of the industry.

Merc predominately uses the Chevy product design and since, as I understand, Merc bought GM's BBC program out they have test data that they can use and build on that to apply stresses from water and displacement detonation, shock load etc. Running a test stand engine gives one set of data but the data loggers used in the actual racing event will give some of the best test data since it is gathered in an actual racing event of max stress levels and all the variations that go with it.

Here they are in the race boat
Yes they are dry, I converted mine to wet. Here is a photo when they were in my 32' Velocity, It was a 100MPH ride but you had to clean the poop out of your drawers when you got thru. I have since added Whipple 3.3's for the 35' Ocean express the photo with the blowers.
