For all those quasi-engine building experts out there I would say take your engine, put it either on a special dyno for 24 hours or in a boat and run it at full throttle for 24 hours and then get back here on OSO and tell us what happened to your engine. Got a feeling you might be getting back on here in way less than 24 hours telling us about the grenading the engine took?
Ilmor and any other manufacturer is willing to take the expense and effort to do a 24 hour full load test on a marine performance engine is way above the bar for testing and verifying the abilities of its engine!
Kudos to them for the effort and the obviously successful results.

Ray, why don't you give us the details of this full load test?
Are they cycling it from peak torque to peak horsepower? That's what the automakers do.
If these engines can't even pass an automotive OEM test, then they are WAY overpriced as far as I am concerned. I wouldn't trust an engine that only had 24 hours of test running. You have to be kidding me. That to me says they are a lot of bling and very little engineering.

Sir, not questioning your expertise as a test engineer only as a marine engine builder. I don't know how or under what parameters this test was conducted however I do know that Ilmor does and has always done a fantastic job of engine design and fabrication providing marine performance engines that exhibit fantastic reliability in the boats under real world performance boating conditions and in many racing applications. I am sure if you contact Ilmor or send a PM to Ilmordude here on OSO they would most graciously provide you with the basis and results of their tests.
Please lets us all know what type of engine durability tests you perform in your position as a test engineer. I am sure many here would be interested to hear about your work, myself included.
Best Regards,
Ray @ Raylar

Ummm... You'd better read this regarding Ilmor's engineering credentials.
You'll have to call Ilmor at (734) 456-3600 for more details on the test. They probably won't tell you everything, but I'll be they will tell you far more than Mercury will.

Good durability test: 150 hours cycling between peak torque and peak HP, stopping for oil change every 25 hours. Since even high performance boats spend a lot of time at idle and part throttle cruise, an engine that can pass this test should provide at least 300 hours of reliable service in the boat. Not many of us can log 100 hours per season so that's quite a few years of troublefree boating.

Having read the summary provided in the link, I cannot really tell much about their engineering abilities to produce a "consumer" product. That doesn't mean they are not doing good engineering, and in retrospect, my prior post was a bit reactionary. Even just to get the engine to meet emissions takes some decent engineering, and my hat is off to them for producing an emissions legal engine with good power.
I've worked for both the aftermarket and OEM's, and they are completely two different types of engineering. I have a lot of respect for engineers that can get the maximum performance out of a design. I also have a lot of respect for engineers that can get the maximum durability out of a design. Those two diciplines rarely meet, however.
I really hope Ilmor is doing more than 24 hours of durability testing for a product aimed at consumers. I would think they would be, especially if they have to warranty it for emissions, but I'll give them a call and see what they say.
I think the question people should always ask is, "OK, it makes that much power, but for how long?"

At the request of Wildman_grafix, I created a new thread detailing the tests we ran at an automotive OEM Engine Durability Testing

do you really think the Ilmore in incapable of that? With the amount of tech and design talent available in house there i am quite certain 2-400hrs isnt the slightest issue. I would assume the 24hrs is just a standard baseline test as these engines live there entire life at just about WOT, something i am sure they are aware of. I do agree they should do a multi hundred hour pull and use that in media but lets face it there reputation speaks for itself. If i had the means these would be my first choice bar none. Cant wait till they have a package complete with sterndrive man i get excited just thinkin about that
