info and education on ilmars please.
 

OK...edgimacate me...:lolhit:...whats the advantage of ilmors over merc????

this is a quite forum...:party-smiley-004:...almost as quite as the sunsation forum:lolhit:

no blowers, lighter weight, better drive/tranny than NXT. Basically same speed from everything I've seen within 1-2 mph. "Should" have higher quality CMI's, but not positive (non-merc spec'd)

Our 725 burns approx 50 gallons per hr at WOT.

Jupiter Sunsation will chime in and tell you about his run from Miami to KW this year.

Has not been a real back-to-back accurate test between hulls to verify speeds.

Lightyears ahead of Mercury in the customer service aspect!!

I'm assuming they are reliable as well??? any of you running the indy drive too????

Do a search in the GD area using "Ilmor". You'll find a lot.

Lesson#1 It's spelled "Ilmor":party-smiley-004:

Sorry, I'm in one of those 'Moods":evilb:

you hurt my only feeling....:angry-smiley-038::drink:

I'm going off the Donzi 38zr 105-107 for merc and Ilmor, and Hustler 39 Rockit ~ 115 for merc and Ilmor. Would love to see a comparison like the 600 vs 625 inthe 39 OL. LINK

The 625 is no longer made by Ilmor, although they have some leftovers. Their only two current engines (Generation IV) are the 650 and 725. I'm a happy camper with my 725/Indy.

I don't see Mercury publishing many comparison tests of the two company's competing products in the future. I would love to see the results of tests from a neutral source, though.

Me too. That article is a bit fuzzy.

Also,

The Ilmor isn't as tall as the Merc so for those that have tight spaces. No need for a scoop on the rear deck. The last comparison I saw on Merc's website had them pretty much even steven....

Does anyone have WOT fuel consumption numbers for the Mercury 700? Given that purchase price and performance numbers are pretty close, the difference may be more pronounced in cost-of-ownership.

What upgrades, (if any) can done to the 550? I take it that Ilmor isn't making the 550 anymore either, correct?
Thanks,
Dean

Dean,
the 550 is not produced anymore. The older 550 can be upgraded to the 625 with a valvetrain swap and ecu re-cal. We will still do new gen 3s with warranty's in 570, 625, 7-10 configs. if anyone wants the original screamers!

ILMORdude,
I sent you a PM.
Thanks,
Dean

No blower- same or slightly more HP
No belt dust all over your bilge
<better top end rush less midrange and low end>
more compact- a tad longer but not as tall
All aluminum
Better mileage
great service and support (this is all about your "guy" though)
better drive- (less parasitic loss)
Factory CMI's

Far fewer computer issues than the merc 700

Lifespan is incredible with little to no maintenance, and some guys reporting hours at 600+ with nothing more than fluid changes.

thanks this is great info...I'll just have to wait for my next boat to get em, not wanting to go through the learning curve in my current boat not to mention the $$$$.

What kind of cost is there to adding the indy drive to a 710 package vrs adding a Merc 6 to the same package.

Looking at the Racers Packages that ILMOR was offering, about $31,000. With less parasitic drag and less weight, the Indy should be a little bit faster than the #6. Don't know about Merc pricing...

Thanks

UD,
Thanks for the info.
Dean

No problem, happy to talk about this product.

I was quite skeptical as to why bother finding a replacement to a BBC and thought for a long time the Ilmor was an answer to a question not worth asking.

I was wrong. Its a very worthy mill thats quite different from whats out there now, and I couldn't be more pleased with my choice after 2 seasons of ownership.

Although not as hip as the new gen 4 725, the gen3 710 isn't far off and it never fails to delight even my most hardcore buddies, and scare my passengers with a push of the stick.

It also delights me at the gas pump routinely getting around 2.5 MPG on long ocean voyages. This gives my smallish boat a decent range on a 100 gallon tank. Ive taken multiple 300 mile round trips and this thing just purrs.

Idles like a kitten around the docks and howls like a raped ape roaring right in between a BBC and a Lambo - it has to be heard to be believed.

UD,
Great pics, I recognize Avalon Harbor/water taxi in the 1 pic. That is great MPG you are getting, amazing! I'm trying to remember what drive you are running on Lavey?
Thanks,
Dean

Bingo - it is Avalon Harbor thats my "pet" run on weekends.

Im running a Teague platinum/BRavo XR

Mileage- pretty incredible IMHO. It makes runs like Del Rey to avalon a cheaper affair than an Imax 3d movie. (really)

Chicks ride for free (of course) and sausages buy drinks and gas- or better yet bring their own rides -

To be fair I don't rail it too hard in the ocean with passengers
I typically run 35-60 out to the ithsmus then when Im in the protected water "Burst" up to about 80-85 for 3-5 mile stretches then calm it down a bit. I havent had a single person regardless of experience or ownership tell me the mill doesn't deliver.

A buddy on the run to Avalon he would stick it up to about 45-50 then push it forward and laugh maniacally over and over repeating "holy-$hit" everytime the mill cracked into the top half of the tach.
