LSx into Jet Boat??
Exhaust Guys, I've been doing a little research on my own. For anyone who is considering this, you've more than likely found out that your biggest obstacle is exhaust. There has been a lot of talk on here about different manufacturers, etc. Well...here's a little info that some of us might find useful.
Crusader 6.0 Exhaust Manifolds:
R028024 CRUSADER 6.0-LITER MANIFOLD - Best price I've found on these is $186.26 from here: http://www.marineandrvpartssupply.co...arts_List.html. They are also available for $249.94 from here: http://marineengineparts.com/shopsit...l/page557.html
R029016A CRUSADER 6.0-LITER RISER - Best price I've found on these is $160.00/ea. from here: http://marineengineparts.com/shopsit...l/page557.html
RM0274 CRUSADER 6.0-LITER RISER GASKET - Best price on these I've found is $23.40, again from here: http://marineengineparts.com/shopsit...l/page557.html
Also, here are the Pleasurecraft Marine (pcmengines) part numbers. The parts look identical, but carry a slightly different part number; I didn't look up prices, but they should be comparable...mostly I listed both sets of part numbers in case anyone is lucky enough to find a used set.
R028023 - PCM Engines 6.0 Exhaust Manifold
R029016 - PCM Engines 6.0 Riser (Elbow)
RM0274 - PCM Engines 6.0 Manifold to Riser (Elbow) Gasket
I don't know if you can buy these as an exhaust package somewhere else...if anyone has any information on the best way/place to purchase these I would appreciate it; but at least now we've got some part numbers out there, should prove especially helpful if you're ordering from your local marina.

Nicson maybe? If that's the case, they're probably 351C manifolds. They'll fit the LS with an additional bolt hole or two. I've got a pair of the Hardins 351Cs in my basement if you want pics, dimensions.
As for the Crusaders, looks like you found pretty good deals.

You're basement manifolds wouldn't be for sale, would they?

Going thru-transom wouldn't look as cool as some OT headers, but it would definitely make things sooooooooooooooo much easier for me right now. I wouldn't have to cap my thru-transom holes, I wouldn't have to buy a Bassett T-valve, I wouldn't have to modify headers to work with water lines.
The only problem i see, is getting the initial tune done....but I suppose I could bolt up the set of Hooker Super-Comps that my buddy loaned me, and tune it with the wideband with dry exhaust, and then slap the water cooled stuff back on?
Hmmm....
GREAT FIND!!!! My mouse finger is trembling, on the verge of ordering this up.

I am planning on an Edelbrock Performer RPM intake and the MSD 6010 for simplicity...so I haven't considered how to tune.
On a side note...you have a PM from me.

Well..........summer is coming fast, so I needed to get something for exhaust....so I ordered up this exhaust setup from Crusader. Right around $800 shipped. Hope it works...haha.
Also, on the elbow of the exhaust you'll need a plug (unless you ordered that too). It's where an optional exhaust switch could be put in (it's circled on the attached picture). I don't know if there's a way you could use that for an O2 sensor bung...but I still don't know what you'd do about the cooled exhaust skewing the readings.

Um....Well...........I cancelled my order for that exhaust. After looking at it a bit closer, the manifolds are so close to the head that the coils have to be relocated. I'm not wanting to do that, so back to the drawing board....
For mounts, I'm using the stock 3 point setup. I made mounts to go from the block to the iso-mounted studs on the stringers.

I think I'm just going to use 351C water logs - sure it's a couple extra holes; but it's cheap and then I can concentrate on the other stuff.
You guys are making me feel guilty for sitting on these Hardins. I've been collecting marine parts, manifolds, mounts, transmission, etc, but just lost my job...So I'm having a hard time justifying a new project toy.
