[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.

[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.
