Ilmor is an engine company that does not put its talent or name on any engine that is not exceptional and a first rate reliable product ,Period!
This engine series should be a great small block replacement engine with a great weight to horsepower ration and excellent overall power and torque.
The real issue here for re-power is whether Ilmor will release these engines without the catalyst emissions systems for re-power on older hulls only as the emissions engine package cannot be modified with headers or otherwise for non-emissions use.
There is no reason you could not use the emissions version though but the engine would be basically unmodifiable because of the special ECM and programming.

Maybe I should explain further for those who don't understand the new EPA required MARINE EMISSIONS ENGINES!!.
These engines even the one talked about here by Ilmor use a catalyst system in the exhaust manifolds which is controlled by this engines ECM. If you take off this system and add headers, -"THE ENGINE WON'T RUN!!" They have special O2 sensors and inputs from the catalyst and fuel systems to calibrate them for emissions and unbolting this sensor system will not allow the ECM to run the engine. New headers currently don' t have catalytic converters in them.
The manufacturers like Ilmor won't re-program the ECM or allow any other party to re-program the ECM to eliminate the catalytic system as that is a violation of federal law and would result in their loss of approval to build these engines period!
The days of just un-bolt the old and bolt on the new with respect to new (2010 and up) marine engines is gone except for two manufacturers may still produce these type of engines for re-power in older boats only as various states may allow!
Not trying to RAIN on anyone here just trying to get performance boaters educated in what the new emissions engines are and how they are currently and practically unmodifiable so they don't go purchase one, buy headers and find out after the fact what they might be stuck with!
Ray @ Raylar
Do the new engines with the cats meet most states decible requirements ?
talke to ilmor they will give you all the info call them talk to ean hawkins734 456 3600
And i have made them myself once to pass emissions on my truck when i had a bad connector and procrastinated too long before getting it fixed and had to go get my emissions done to renew my plates!
Money can't buy happiness, but it can buy horsepower. And I've never seen a sad person hauling a$$!
