Since they make 10 hp more that the same basic engine did 10 years ago, they will cost $10,000 more.... :angry-smiley-038:

well they will bang you for new exhaust with cats,closed cooling fancy belt set up so in 94 I payed 10,500 for a merc 502 so now I bet 18,500 would be the new price anyone know a price for bob tail?

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.

Why such a quick departure from the 496's? I thought the 502 block wasn't in production anymore.

I think cause GM dropped the 496 in 2006 the source has dried up. Steve

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.

....or you can still buy 496's from Volvo Penta, who stocked up on them.

Good point.

WOW, I am so impressed, Merc is going to charge more for a "new motor" 502, to replace the OLD 496, BUT didn't the 496 just replace the 502, and add $$ to it. I owned boats with 502 efi from merc just 10 years ago.

I am just going to call it like I see it, this is an excuse for MERC to stick it to us again. Keep it up Merc and you are going to drive all of us to OUTBOARDS and no they won't be verado's.

I am looking to replace a verado right now, and looking very hard at SUZUKI. Everyday I haven't had my BIG BLOCK mercs has been a day without head aches.

Boat emission testing?
