Call me stupid but wasnt MAG for carbed engines and HO and MPI/etc fuel injected. Unless it changed later on

No. The Magnum name was simply a name given to higher hp "black" motors with forged internals such as the 454 Mag compared to the standard 330 hp 454 ect, and are not to be confused with merc racing. The Mag's came as carbed and later as FI engines. For the injected engines, the terms was EFI and later MPI. The EFI was a TBI setup and the MPI of course a Multiport. Nowadays it seems that the name just carries over for the new 8,2's as it did with the 496's from the 502 and 454. My guess is, that it's more of a marketing thing than anyting else, for the high hp black motors. There was certanly nothing "magnum" about the 496's with all the cast internals. The 350 still carries the sticker as well. Maybe someone has a little more insight of the origins of this name?

You can check the ECM also. It will have" H.O." on it if it is in fact a 425hp. Would be a slim chance someone changed the cover but I've seen stranger things.

Who knows, I'm gonna call Fountain tomorrow and find out.

How about speeds with twin 6.2's
 

Anyone have an idea what a 29' fountain with twin 6.2's speeds would be and how it would handle. I have seen a couple of them listed in the classified ads, just wondering what kind of speeds you would see. Seems like that might be a nice combination.

The late model 29's with a pair of 6.2's will run 70-72 mph. They weigh ~ 7000 lb due to the 2nd engine and running gear (drive, transom plate, etc), compared to 5850 lb for a late model single setup. They were/are tough to sell and seem to go pretty cheap, when they do sell, from what I have seen.

Maybe somebody changed the big metal thing the plastic piece is attached to..............

Well I talked to Fountain and it looks like someone swapped the engine and my outdrive. It came with a 525 and a XR and now its got a 496mag, obviously, and a Bravo 1. Awesome!! J/K Well I guess somewhere down the line I might want to repower it.

Hey you could do a raylar kit.

My guess is the past owner stopped paying for the boat. Took motor and drive sold it for some big coin. Bank repoed it and threw in the cheapest drive and motor for a 29.
