I agree. The 572 custom built engines, trannies, Gaffrig headers with Gaffrig silencer tips, and #3 SSM drives are worth quite a bit. All the engines parts are top of the line (especially from 10 years ago) and the 12 qt Gil pans add to the mix.

Yep, both engines fired up and sound great in person. No leaks in the engines or the headers.

My understanding is that only about 30 sets of these Gaffrig headers were made. The middle section can be taken out.

We only did a visual check before firing them to make sure they ran.

Onwards, Bill

I shoulda grabbed that... chit... lol

I'll sell you some 3's and gimbles way cheap!

Quite honestly, it was a gamble that could have gone either way. Jim (the seller) sounded straight and honest so I took the leap of faith.
I hope to have the engines dressed out and installed in a couple months.

Let me know when you decide what you are going to do with the hull and Trailor.
Rick G.

either way it was still a deal even if engines didnt fire.... TONS of parts there

I will be selling the boat and trailer very soon. If you want to talk more, just email me at [email protected] Bill

Ignition systems
 

The carburated 572s now have older Mercruiser V6 ignition systems, but I don't believe there are rev limiters. Does anyone have a suggestion on what ignition system might be better? I am leaning towards the MSD 6ML package with the billet ditributors, but I am open to suggestions. Bill

Bill I run 605 cu in N/A big blocks in my flat deck and I run the msd 6 ml boxes with merc distributors without issues. My motors make about 725 Hp.

FWIW, I'm a big fan of the Thunderbolt IV w/the V6 module. It works well for your application, simple, reliable and can be diagnosed with a test light. No, it does not come with a rev limiter, but if you have to have one the HP500 carbed rev limiter will connect right up to the TB IV.

I've experienced too many MSD failures to ever consider that route again.

Biggus I can't argue with you last year had a small short and blu the port msd 400 bucks later solved the problem. I my try your set up this year.
RG.

Only problem with the merc ignitions is the early rev limiters caused some severe problems for me last year. Other than that great systems.

I agree! Between me and my close boating buddy, we lost a total of 4 msd boxes in 2 summers. He lost 2, I lost 2. At 350 bucks a box for the marine ones, unacceptable for me. Switched to Crane myself. Heres a pic of the internals of each. You be the judge.

Mild is right!!!! Crane is the way to go. They hook right up to the MSD coil and Distributor. It also has a indicator light to show you whats going on and built in adjustable Rev limiters. Plus they are black and go with every paint option. It sucks running with a spare MSD box waiting for it to go out.

Yup. That blue box didnt go with my scheme at all. Not too mention, you can find the Crane 6000-6440 Digital race box, with built in limiter and diagnostic function, for around 200 bucks. The MSD marine 6560 is almost twice that, and isnt even a Digital box.

Dammit another thing you clowns are gonna make me order aren`t ya?
Someone hit me over the head with a lol stick!:lolhit:

Thanks to all of you who responded. I am going to have to ditch the idea of the MSD 6ML and consider getting the rev limiter for what I already have - the Merc V6 box. The Crane box also sounds good since I wouldn't have to get a rev limiter and it would be a new system. Onwards, Bill

Bill,,remember that rev limiter box i sold you for your corvette,, well that can be wired in with the ignition,,boublr check on msd's website first..also you will need to buy the msd rev control box's for the msd 6ml..

or daytona sensors make a better box than msd..set it with a laptop..http://www.daytona-sensors.com/CD1.html

ps the daytona box looks like what crane use to sell,,crane box's are NLA so the daytona sensors are a identical match to cranes..

Ditch the MSD. Cost me a couple tow ins, and eventually an engine. Theres a reason "if" you see them in a race boat they have two moduels and a switch to change over mid race..

And spares in the truck....

You don't have to order anything but a U.S. Tow membership if you keep that other box

+1

The cranes also have a tach test feature which is cool. The Daytona sensors boxes are top notch, and do some really cool stuff. But they aren't cheap. Same guys who designed the crane box

I don't think the Cranes are USCG approved....

Correct. They are supposed to release another marine box soon i was told.

Stainless braided fuel line is NOT uscg approved either. Just sayin since we are on the uscg thing. Neither are my spark plug wires or plugs for that matter. :(

crane was at the pri show at pheasant run last month,,they looked confused when i asked when they were going to come back out with the marine ignition again..it dont look promising..
