The 496 has proven itself to be a durable performer. The supercharged LSX will be engineered by GM with greater durability than any of the Merc HP packages, you can count on this. Adding pressure to a motor with existing technology in the aftermarket is a far cry from an as designed, team developed package that would eminate from a major automaker. Sure, someone like Ray or Bob Teague can make you a nice low volume motor, but the 2 of them put together couldn't even supply one decent sized boat builder. A custom design philosophy is left for those who can apprecite (and afford) it. Again, if this motor is released, it will have GREAT durability. This motor is now a better fit for GM as the economy of scale is rendering the 496 obselete(in the production sense). Take Care, Dave
Well, seven years later after the 496 was released and I'd still rather have a 502 415hp mag. |

Supercharged 6.0 504hp marine engine by kodiak. Looks like they also have a supercharged 383 :evilb: |
Looks can be decieving?
Nice looking package by KME, but you should ask to see the horspower and torque printout??
Curious what the pricetag and warranty are? I dont see any closed cooling so this looks like a chancy proposition in all but the purest lake water?? On that type of a centrifical supercharger the boost is usually late on starting in the rpm band up around 4500 rpms or so. With only 6.0 liters I suspect that this engine will only produce about 350 ft/lbs of torque around 3500-4000rpms where most cruising rpms occur, UNLESS its already in BOOST and there goes engine life at cruise rpms!! I also don't see an intercooler on this package and supercharging without an intercooler on a marine high performance engine is just shy of playing RUSSIAN ROULETTE with THREE bullets in the chamber!! Not here to pick there offering apart, just want you guys to carefully realize that there are a lot of factors at play here when you try and get small cubic inch engines to perform like big cubic inch engines!! There is no free LUNCH! Raylar thinks it's LSM550 big cubic inch 434 small block -naturally aspirated is the obvious answer! but heck I am biased! and What the heck do I know? Best Rgards, Ray @ Raylar |

It does come with closed cooling standard, it's just inside the stb manifold. There is also an intercooled option. We dyno'd one last year after redoing the top end. The biggest problem with that package is the base tune from the factory is not very good with a stern drive. A jet has a way different power curve then a stern drive. It was very smooth and sounds great but in the boat it gives you about the same performance as a healthy 454... I'll dig up the dyno sheet and post it, or if anyone is calling KEM talk to Carl in service. He's about the only one that knows anything there. :drink:

I found on another tread the price tag would be $ 20000 !!
I would spend a little more and go for the lsm 550 ,more hp ,lightweight,closed cooling and lots of R&D behind it . |

There will be boats on the water very soon with the LS9 in them.
They make 650+ hp in the maranized "racing" form. |
