Not sure if this is in the right section. If not, can someone let me know where to put it.

I live in TN, and I have been looking for a jet boat project to play with for quite some time. As some of you may know, there ain't many out this way, compared to Socal. I found this beast by word of mouth. Been sitting in an older gentlemen's shop for a good while. It ain't seen the sun in about 3 years. The man has owned it for 18 years. Anyways, to the boat.

89 Liberator 21 ft. tunnel, 468 BBC, mild work done to it. I'm thinking a Dominator pump? Hydraulic diverter, and a pump ratchet(first time i had ever heard of this). 850 carb, flowed to a 900, and (2) 21 gallon side tanks. I should have had a pen and paper, because this guy was spitting info out faster than Google. Said he's been racing jets since the early 80's. He has a list of everything done to it, maintenance records, etc. It isn't for sale to the public, he said he wants it to go to someone who knows what it is. His words"not some young punk, who's gonna go out and get people hurt with it". He's asking $12,500 for it. I haven't seen a whole lot of these, so hard to find something comparable. Any thoughts would be greatly appreciated.

Here's some pics

Last picture he gave me, so it's a picture of a picture(kinda hazy)

Last weekend I had a power steering line bust, or rot and crack, and leaked ATF all over my engine compartment. The stuff smells like doo doo. Does anybody know of anything that will take out this smell and not mess anything up, fiberglass, carpet, hoses, belts, etc?

Thanks in advance

I got a 83 Carrera open bow, 21 footer. It has a Volvo Penta 350 and a Volvo Penta 290 outdrive. The motor got HOT and is gotta go( spark plugs are caked with water/oil mix).
I found me a Vortec 350 outta a 05 Mastercraft with the Electronic throttle body. The computer(ECM) is still hooked up and is a, hook the hot and ground up and go(plug and play). The motor has about 20 minutes on it. It also has a cracked block( in the same spot as usual, beow the exhaust manifolds). I am going to do a JB weld job to the block.
I have the money budgeted to have a shop do the work, but am considering saving the money and doing it myself.
How big a job is aligning the motor with the outdrive?
Do I have to have any specility tools or can I imprevise?
Will the 290 outdrive hold up to the 340 HP from the new motor?
Any help would be much appreciated
