5y/100,000mi warranty to boot.:eek:

That's a pretty sweet little package with some pretty lofty claims right there... The price is a kick in the nutz, but if it is everything that they say it is it sounds like it might be worth it.

It's about time.

Interesting, how the specs differ from GM to to Panthers spec.
Stilll me likey both!
Merc's not gonna carry these will they?
The LSA is nice competition w/ the 525.

That place is just down the street, I might have to stop by and check it out.

ANY NEW'S ?

Weismann is building 650hp small blocks, or at least someone they know is.

Yes, Ive seen the advertising and the claims. No, I am not a Guru of small block performance marine engines. Have we developed and built several larger cubic inch noramlly aspirated LS based engines, you bet!
GM does not back a warranty on this supercharged crate engine for marine performance usage period!!
When one or two are in a boat and have run a hundred hours or so with no problems, then I will say they might have really got something here.
Ponder this, if this supercharged 365 cubic inch engine is so good for marine performance usage in moderate size boats why did Mercury, Volvo, etc. pass on its use and development. Could they also know something most others don't?? Humm? I know they tested them extensively!
But hey, don't let me stop anyone, go ahead and buy one or two and give'um a go! I love to hear success stories!

Best Regards,
Ray @ Raylar

So basicly they just took this crate motor intened for an auto and marinized it for marine and the only warante you would get is from the builder " that i never herd of "
like you say maybe someone will by some that is on oso and try them out , i guess it could be a hit or mis , hopefully a hit ,
i thought about it as far as price go's it seem's like a good price but once you add on a xr drive and hp transomplate you could have bought a merc 525 or save a few dollar's if you are just repowering and get one of your 496 upgrade's

Raylar,

Your opinion is further validated by what happened with the 525hp marine version of the 496 GM tried to field when the 496 first came out. One had to know that Merc could probably have sold a 525hp engine at much lower cost than their blue motor using that package. But Merc knows things about marine durability that I doubt GM has a total grasp of, and Merc only kept offering a much more expensive package. I'm probably a witness to Merc wisdom with my 9 year old 500 hour bone stock 575's. Merc knows marine durability.

And what happened with that 496 based 525hp says something else about offshore racing. You can be competitive and even win with an engine that will not have long term durability in the commercial environment.

Nope,
Sorry I havn't made it by there yet, too busy working!:eek:

I find it interesting that on the GM links it says marine engine but it shows it with auto exhaust manifolds. also says that the availible option is the ECM kit. how are you supposed to run this thing without an ECM that is setup for the application?
