Aluminum heads, detuned 525EFI with a cat exhaust. Removing the exhaust, replacing with CMIs and a reflash will be the big first mod IMO and should yield some results.

Lets hope most are happy with 380-430HP max!
For all those hoping for a bunch of mods for this new catalyst equipped engine with Mercury's new Motorola ECM, good luck!
Until someone gets there hands on the new Ecm's, spends a whole lot of money and time to possibly write successfull new complete engine programs, the ability to modify ,even with headers is out of the question and pretty much against the law!
I know some Merc sales types were running off at the mouth about CMI header upgrades and such, but if Merc is going to stay with emissions as required by the new 2010-2012 standards, those ideas are a long way off and just speculation and unfounded talk!
We have the programming capability on the PCM555's we just developed two years or so ago and it will be a while before I think anybody in the industry will take a crack at this new ECM, especially with Merc's new platform and proprietary technology.
These new 502 engines also have to have by law a three year emissions system warranty and that means no messing with them at all for three years or the warranty on a very expensive engine is out the window.
I believe these new engines are selling to the dealer and boat builder for about $23-$24K a piece so they are a big jump up from the 496's they replace, that were going about $14-16$K per engine. If you are in a state or area that allows the Merc HP525efi engine I think for the difference in price I would opt for the slightly higher price tag of the 525 over this 502 and stay away from this cat-emissions technology until its proven reliable and successful as I think Mercury will have their hands full with some bigger than life warranty issues on these new complicated emsissions systems and unproven equipment. Just a thought and two cents thrown in.
