LSx into Jet Boat??

Yes, most boats do run rubber hose both on the fill side and between the tank and motor, but that is (or at least was from the MFG) USCG approved marine hose (can`t remember if the spec is a double wall or tripple wall). But none the less I would recommend hardline in a retrofit EFI boat, because the common USCG approved hose is not rated for EFI pressure. I`m sure there is rubber USCG approved EFI spec marine hose because there are production EFI boats now, I`m sure it would be very difficult to find someone who stocks it.
I will say that I know people who have run boats without the proper marine components and I have ridden in their boats and did live, I will not say that is the correct thing to do, or that the marine components are the same as automotive. I was never stopped by a cop to check that the boat had all marine components, but I have heard of people being stopped and ticked because their stuff wasn`t marine. If you really don`t think there is a difference just ask the insurance adjuster after there is a fire/explosion.....first thing they do is check for the certification on those parts.....and deny the claim if they are not all USCG certified.

As G Body pointed out, use USCG approved rubber line from the tank to the pump. It will have a USCG spec printed on it.
Consult with your insurance company or policy before taking Krom's advice.
The Water Patrol around here never looks at that stuff, but the USCG has before. I'm less worried about that vs the insurance Co denyng a claim due to unapproved modifications. A boat burned on my dock last year, took out a few boats around it. That could have been really expensive if the insurance Co denied the claim....or worse if someone got hurt.

Got some parts last week. My PTO showed up. It was pretty expensive, but I am time constrained, or else i would have machined my own. It's a nice piece of hardware though. Also got some parts from Patriot that I was waiting for to get my valvetrain squared away.
Patriot Golds installed.
New Spicer driveline from Rex Marine.
Awesome! Overall length remains the same, nothing has to move, as far as engine mounting is concerned.
Going to run a liquid to air, engine oil cooler. Will mount this back, behind the engine in the transom.
Couldn't find ANYTHING in M28 threads, so i drilled and tapped the original plug, to allow me to put a ball valve on it for easy drains, and clean-outs.
Manifolds showed up!
It doesn't look like it in this photo, but those first three holes in the head line up perfectly with the mounting holes in the manifold. I have a 351C exhaust manifold gasket coming in to the parts store tomorrow, so I will get a better pic then.
It's hard to see here, but two of the holes from the LSx gasket line up with the ford manifold.
Glamor shots
The intake will more than likely be flipped 180 like it is in the second pic, once it's in the boat.

Are you going to use the existing oil cooler holes or an oil filter adapter?
BTW, been looking at this, it's been for sale for months:

Someone talk me out of it........
Oh yeah, anyone know if the Corvette coil/rail covers will work with the truck coils?

I have two options for the oil cooler. One is using the existing holes in the GTO pan, the other is to use the adapter that bolts to the pan above the oil filter. The one i have came off of the 6.0 when I got it from the junkyard.
Not sure which way i'll go yet. I am not sure that the truck oil filter adapter will work with the GTO pan.
That old boat looks pretty rad. Wonder what kind of condition the floor/stringers are in if it's been sitting outside with no cover on it. Bummer on the jacuzzi pump, too. But for $1500 I could probably overlook a few things

I am not too concerned about it. The pan is very well baffled, and the bow doesn't really rise all that much on a jet-boat when you punch it to come on plane.

UPDATE: The motor is in the boat, and bolted to the stringers, and to the pump!! Also got the Hardin 351C manifolds bolted on. Pics to follow when I get a chance to upload some.

Looking good. Those logs are gonna cost you some power though. I've got a LS1 lined up but kinda want to go with a LS2 and try the 408 route, maybe with a F1 Procharger in a 19 Daytona or Cheyenne.

Plus, the logs will be a good starting spot for a twin turbo setup if I go that route next year...

Been slowly working on this thing...hoping to fire it up later today if I can get a few more things done on it....
Started on the wiring...
Got the fuel system finished up. Ran a Bosch 044 pump, with a C5 vette filter/regulator. Ran a return line back to the tank.
Fabbing up a battery tray to mount my yellow top Optima inside the boat.

Guys...I bought a PTO adapter from CP Performance. It got here, and the bolt holes measure 3" center to center. My LS1 measures 3.15" center to center, so it doesn't fit. I called CP and they called the people who made it, who said the 3" center to center fit their LS1's, also CP said they sold 2 other PTO adapters and hadn't heard anything about them not fitting. They are still trying to get it figured out, so they are working with me...but in the meantime I have a boat project on hold.
Any ideas?

This thread has been very usefull in designing the pto to my hydraulic pump. I will machine one just like the aluminum one pictured. Alot of good info in this thread.
