Mercury Racing Unveils 565 Engine with Digital Throttle and Shift
 

Happening right now, http://speedonthewater.com/new-boats...and-shift.html

getting real close to the 600sci...

Awesome!

Instead of all these new motors,how about a Bravo replacement from Merc that can handle a 525,565,600?

That and a replacement for the headers that are shown on that motor.

The interesting question here is, how does the price compare to the 600SCI and the 525, also how does it compare in terms of rebuilds. My guess is, that there will be a replacement in 2013, latest early 2014 for the 600.
I like the look of it. Let's see if they have stepped up and installed high quality headers this timeCouldn't agree more. Bravos suck!

Sounds like a bigger better 525. Works for me.
I'd bet it will eventually replace both the 525 and the 600sci.
I think the Bravo 1 XR is only good to 600 so will still work as a good package.

A nice thing would have been to use an alu block, that dissapoints me a bit. It already have closed cooling.

Mercury Racing and Ilmor doing nice things to try and stay in a dead heat in the 500-600HP pushrod V-8 range engines that are emissions compliant!
Nice job done by both!
Price may be obviously a big factor in this economy.

I think there must be alot left here power wise thought as our Raylar 540 cu.in. reworked (HP525efi) HP675efi makes 675 easy HP and torque very close to that of the HP600sci ? I think again this is propshat horsepower which really puts the engine about 600HP crankshaft.

Congrats to Merc Racing and Ilmor for their nice new offerings, they obviously are doing ther homework and look to be bringing nice new products to market.

Curious what both these two new engines will sell for?

I'm kind of surprised that they did not do a NA version of the 1100/1300 ohc engine. I'm sure there are reasons.

I would think that they would have made it so it could run on 87oct.

A N/A 1100 QV4 Merc Racing engine would cost 2-1/2 to 3 times what this new 565 will cost. Not to many builders or buyers gonna be interested at that price point. This is why the 600sci and 700 sci's will be around for a while also.

I'm personally surprised they band-aided the Ram Jet style intake. I know this configuration has caused a lot of gripes with a lot of builders that attempt to get more power out of these motors because of it's deficiencies. Looks like a new upper with two throttle bodies bolted on top of it. Never seen that done before.

Funding...

...and 20 minutes later, ILMOR introduces a normally-aspirated 7.4 liter engine that makes 570 horsepower, weighs 300 pounds less than the 565, and has about 50% of the bells, whistles and bull$hit of the 565. ILMOR's 570 is based on LS architecture, features variable cam timing, and passed their in-house 24-hour WOT max-load durability test.

Mercury has intoduced a pig that looks like a plumbers' nightmare. The intake looks like something an Arkansas hillbilly would rig up. (No offense intended to our Arkansas members; you could probably do a far better job.)

On the drive front, look for an announcement from ILMOR in about 8 months...

I am continually amazed how much Mercury has dropped the ball by ignoring the potential of the LSx
motors, they are literally digging their own grave..By the time they wake up Ilmor,Raylar,Indmar and everyone else will be way ahead of them, they may own the exclusive 1300hp market but they are gonna lose the everyman market which keeps them afloat..
They are still selling 305s 350s and 383s based on 60 year old technology...
Sad...

Look at our Avatar and the plenum on our HP675efi and you can see there are builders out there with solutions for the Mercury EFI manifold.

Ilmor 570.

Ever owned an LS /6.2 gm powered vehicle (cough Escalade.. wish they kept the 6.0 that was a much better engine)? I am highly suspect of GM's quality/assembly of the 6.2s. Great performer but I doubt the durability especially in large numbers of marine applications. Just my preference I would rather have a 502 based engine for marine use. Will be interesting to see how they perform over the long term, starting to see more 6.2s in skiboats too.

My first impression is that the 565 might be the ugliest high performance engine that I have ever seen. Whatever sexy is, that is not sexy.

"Hey open up your hatch so we can check out your engines!" Ehhh, you can go ahead and close it, please....."

Crappy cosmetic design- puke :wuerg019: http://www.runemasterstudios.com/gra...mages/puke.gif

+1. Hope to God no one takes that shroud off. It's really hideous underneath.

The engine cowl looks like the one on my lawn mower:lolhit:

I was talking as a replacement for the outdated 305/350/383 ..
And yes I have owned LSx engines, never had a problem with reliability.
Doubt Raylar , Ilmor and the rest would be using them if there was...

I suppose you could spruce the top up to make it look like a set of twin carbs with the loss of the shroud and some better looking spark arresters.

But yeah, as is, it looks like the two warts on Lemmy Kilmister's face (see MotorHead). No offense Lemmy!

Tyler Crockett modified the 525 intake manifold similarly a few years ago and picked up a whack of hp. This is a cleaner solution though.

This motors looks to be a after thought!

Looks like the alien head from the movie aliens.

Tough crowd here ...

Looks like allot of great engineering to me :ernaehrung004:

I don't think Ilmor usees a GM base engine for thie one. LS block yes, but I think the rest is Ilmor spec. The LSX block is one bad azz mofo.

Chuck, an answer to this?

Heey, that's unfair to Lemmy. Lemmy is god:thankyouthankyou:

+1
thats what I thought too.. Guarantee someone will custom paint it to look like it some day!

You are right, I knew there was something familiar about the looks of it, and I hated it but couldn't put my finger on why. :party-smiley-004:

I'd take Ilmor all day over this. The 565 looks worse than the 502HO. FUGLY

It sure runs well in the 42 Nor-Tech Monte Carlo. I went out in that boat yesterday. Plenty of torque. Just eased up on plane. Very quiet with x-haust, yet still good sound. Digital shifting is smooth. Speed is in the mid-eighties. Very fast for that size boat, power level and price. 8.7L displacement gets my vote.

Im ok with it...not much diff than the 1300's when it comes to unusual looking..its just different..its a change ..

Jealous,
wish I could have gotten a ride, thats one sexy looking boat!

24 hours??? Whoopty doo! I hope that is a misprint. The auto companies run 200 to 400 hours of WOT. If it isn't a misprint, remind me not to buy an Ilmor engine.

Michael

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 :D

When the Ilmor guys told Mercury about this, Mercury's response was "Why are you going so long?". Maybe we should all put car engines in our boats... ;)

I'm sure that the 565 and 570 will both be reliable packages. Competition among engine manufacturers is good for the consumer.
