The Viper motor they are based off of push 1,500 hp with ease in the Vipers. 1,700 to 2,000 is getting to be the new norm. Even with that kind of power they are very reliable and street driven. Both of my Vipers, one super charged, have been bullett proof. When I buy my go fast boat it will have Ilmore's. Sorry I can't be of more help as far as the marine application goes, but man do those cars fly.

We've run with that boat before at 90+ for a good stretch. Boat runs real nice!! I have also been on it and will be at LCM in a week. It was owned by a guy up in NH on Lake Winni. The boat is in very nice shape and you will love the boat!! Let me know if you want me to check it out while im there again.

Providing the have been maintained your probably not half way to a rebuild as of yet. (Supposedly Ilmor has not received engine 1 back for a rebuild yet)

I decided on Ilmor- and I believe there is no finer naturally aspirated engine series available.

Im a brand new user- and there are plenty of high hour Ilmor veterans on this board, you can look up my write up in the "ilmor 710 forum", and read about other big cat owners experiences- all good expect one guy claiming the wouldn't honor a "trade in" deal. (big surprise never seen a vendor do it myself)

As for what to expect out of the rig -

GUESS coming-

I Couldnt really say, but a crude guess <based on a lavey 39 evo going 106 with twin merc 700's> guess would be 96-101 on a cold day.

The last powerboat test of both with similar power showed the lavey a bit slower on top but waay faster in the midrange - theorizing if propped identically <they werent> they would achieve within 1-2% of each other top speed wise.

As for the mills this is NOT a guess- These are no excuses stone reliable, latest generation pieces (well the 625 is one gen back the 710 is the new edge)

1. Ilmor is an engineering company with the capability to design and build anything up to and including WINNING formula 1 /indy car engines

2 The guys working there have more mettalurgy and engineering degrees than a russian protractor.

3 Is a Roger Penske company and they do not take shortcuts.

4. Ilmors proven track record does more talking than any one person or group on this website- check it out.

The OL looks awesome Im envious.

I did a lot of research on these prior to making the plunge. Haven't put too many hours on mine as I just picked it up... but I can tell you that it sounds sweet and runs awesome so far. The fellas at Ilmor have been GREAT to deal with and from everything I've read, they back their product up 110%. I had a minor issue (unrelated to Ilmor), and the guys at Ilmor did everything possible to help resolve the issue. Great crew out there!
