Ilmor Marie Engine
 

looking at a boat with 625 Ilmor engine how reliable are these engine and what is maintance requied. also how many hours before rebuilds?
thanks

anyone?

Do a search, Ilmors have been discussed many times.

I have a Ilmor 625 and really love it. Don't know about rebuild hours but the staff at Ilmor is great to work with. No complaints so far.

The best - period.
 

Ilmor is the sheite my friend.

As for the hours supposedly ilmor hasnt received engine 1 yet back for a freshening. 3-400 estimate on a 625 with only fluid changes. Its closed cooled.

My 710 gets 2.4 MPG and pushes my 27 ft boat 90MPH

Ilmor is one of the finest engineering companies on the planet.

Ilmors record speaks volumes more than me or anyone person on this or any boating site.

They idle like kittens and scream like 2 stroke dirt bikes.

The guys at Ilmor build a fantastic powerplant, great power, reliable, great looks and wonderful after sale support. Their new drive is a beautiful part also. You could not go wrong with an Ilmor package!

I believe they have way less EFI sensors on their engines, And that could be a good thing, Less problems on the engine to slow your day of boating, because at some point you may be needing to look for why your warning horn keeps going off every 60 seconds with the other guys.:eek: Also if you can find a dodge auto dealer still open in you area they can plug in and run a EFI test with their same scaner tool they use on their cars/trucks. From what I under stand it is the same engine as the viper car they have.

Uncle Dave,

Can you comment on Ilmor price vs. Mercruiser? Ilmor 710 vs. 700 mercruiser? Thanks!

[QUOTE=TCBoss302;2879422]You said you were buying 600 not 700 ?

[QUOTE=gnorthga;2879433]I think the poster is looking at a boat w/625's in it already.

When I priced out my boat I looked at bot the merc 700 and the Ilmor and Lavey would have built the boat with either for the same price.

The 700 merc would have come with an NXT
The ilmor came with a teague platinum and an ITS

I love my Merc products and have nothing bad to say about them, they have been good to me for decades and Ill continue to consider them every time based on a lifetime of love.

What I really liked about the ilmor was 2 things

No blower- Ive had a lifetime of f-ing with blowers and cleaning belt dust from my engine compartments, I know how good the new injected blower rigs are but it is what it is.

About 150-200lb lighter. - Ilmor is all aluminum

One downside was that the Ilmor had no NMEA 2000 compliant computer- they have addressed that with the 725.
Other considerations for me were-

Teague 800 - no fresh water cooling
Raylar 750- incredible beast -& the best looking package available - awesome but rare.

Ill never take anything away from any of these other fine marques, and simply feel after owning and using one now for about 40 hours that Ilmor is among the best in every category.

No one should shy away from an Ilmor powered boat.

Does anybody know how long the valve train typically lasts?

I suppose I'll jump in here. My 2007 710 has 117 hours, 93 mph in a 24 Lavey bowrider. I have done NOTHING to the engine but oil and filters. I have an IMCO SC which is a nice piece but just a glorified XR. My normal deal is to trash 2 drives each year and all I've done to the drive is change the fluid at 25 hours. That is to say, the Ilmor is not hard on drives either due to the peak torque at 4500 or so rpm. I've run the engine hard (6300 rpm) for an hour at a time and it likes it. I've run at 2500 rpm for hours and my wife and the engine have both liked it. It is preforms perfectly throughout the usage range.

The only thing I could say about the 710 that I don't like is that I don't have any chance to do stupid experiments with various parts like I've done with BBC's. I guess I'll have to be content to not being broken.

My next rig will have one or two of these 700's in it.

That was before you sent your boat to Fountain and became a member of the triple digits club.

I don't know of a single valve train issue - whats the skater guy got 800 hours now?

Other than a bad batch of valve springs once they traced and fixed on their dime sending ilmordude (I think it was him at least on the west coast) to peoples houses! (Jeff at laveycraft confirmed this with me)

Its a hydraulic roller (the 710 is never looked at the others but Id guesss they would be) so its always adjusted- no valve maintenance.

If you had the money today- and asked Ilmor to create an brand new engine that would win Indy (or any other motorsport) next year - they could and would do it.

You just have to spend the money.
They have the technology- in house.

These guys have VERY few peers and more degrees than a Russian protractor.

PS: Yes - I ripped off Quents paint scheme
(before you guys scanning the sites doing research call me on it )

[QUOTE=TCBoss302;2879701]The fountain looks great TC, sounds like its got a tweak or 2,these 700's can make huge beans when leaned on just a bit.

I bet its a blast to drive.

I'll go half and half...two of your 750s and two of their drives in a 3100 American Offshore. You win they win I win! :)

800 hours on a 700 HP motor, that is very good no matter how it has been run.

The only problem I see..is the marketing of the drive issue..and hopefully that will be resolved in the next few months. No bravo drive will ever compete against a NXT or something with a tranny..

thanks guys I went for a ride in the boat and all I have to say is wow. what a great power package!

Not to throw stones, but I recall seeing that 32' Skater for sale in TX a few years ago with a blown engine (Ilmor) and it did not have no where near 800 hrs on it. Wasn't it for sale from Bud Bloom?

lets get a hold of him.....
 

Telling the truth good or bad isnt throwing stones-

At the the same time a bit more info than a "recollection from several years ago" would go a long way.

Id love to hear his story- send him a PM if you can and lets hear what his side of the deal is.

Id really love to hear what may have happened because I would have mailed him personally before I bought if I'd seen a story like that.

Anybody got a link to a thread he wrote about his experience- I don't know anybody with a blown engine that doesn't yak about it.



UD

Doesn't sound right to me. I think it's BS.

My personal claim was 3-400 hours-

I also said I "wasnt going to go that far out", but these units last a Looong time as long or longer than their v8 counterparts of similar output.

That data came from the same inquiry posted on SOS- here's his quote verbatim.

I believe the current ILMOR record is a 32 Skater with twin ILMORS & 800+ hours and ZERO FAILURES. Thats pretty impressive!

Anyody know Dave P and if he is or isnt a story teller?

Let see if we can contact said skater owner and get him to verify this claim- Id like to know.


UD

Not as much as the Liberal B.S. that spews from your mouth :evilb:

I think you should call Ilmor and dispute the claim :lolhit:

Nope - not a story teller. Call Bob Mason @ Ilmor for details :drink:

Seems to me Dave P stands behind his claim.

UD

DaveP is Dave Patnaude, longtime Charter member. We've had our differences with politics but he's not into exaggerations and mendacity.

LOL how did you like the President's speech today? Earthshaking to say the least wasn't it? :D

That liberal panzy ass...........he is having fun redistributing the wealth of america!

Case closed on Ilmor....
 

Case closed in favor of exceptional ILMOR longevity-

Politics to be decided when the current regimes #'s show.


UD

PS: its all about the #'s

Best thing is his name's not BUSH. Our long, dreary eight-year national nightmare is OVER thank Reggie. :D

Back on topic...
 

If Ilmor can build a marine motor that can go 800 hours before so much as a valve lash, that is an incredible achievement. Three cheers and a twitch of the Catman's tail for them! :drink:

Now there's a man that never tells a lie:lolhit:

Here's a fact you might find useful: In all the boats Powerboat magazine has tested with Ilmor engines—and we're talking at least a couple of dozen now—only one of those engines has had a mechanical problem during testing. Not speaking as an official voice of the magazine (or "endorsing" Ilmor), just telling you what I've seen.

Have a great weekend.

If that has carried into thier new drive sounds like a nice option. Cool.
