Vortech on 454's?
 

I happen to run into someone with the same boat as me while out this weekend. He happens to have vortech superchargers on his 454's I have the exact same boat just stock ( Baja 29' outlaw) he hasn't been able to sell his boat so he's debating pulling them off and selling them. Im thinking about jumping on the deal but Im also worried and thinking about what else I should do on my end. I have approx 580 hrs on both motors and so far have been pretty lucky with zero issues. Is there something I should do to my motors before even thinking about installing them?

Which 454 do you have ? forged or cast internals ?

Putting superchargers on 580hr engines is like lighting a short fuse on a time bomb.

Like griff said, waste of time to supercharge those motors at that high of hours without going into them. Valve springs are sacked out and head gaskets are prob on verge of leaking amongst other things, Smitty

What year did they start making the internals forged? They're from 2001

Thats why I wanted to ask beforehand. But are you saying its not worth it all? Or I should at least rebuild them first before even attempting to put them on. Only reason Im asking is because he wants to sell me both complete polished kits for $5,000

It’s not just a matter of forged internals, but ring gaps, better gaskets, servicing injectors, etc. so it would be a wise move to build it once and be done, then party on Wayne!

Forged internals would be worth rebuilding, cast is a waste of time with a supercharger.

How do I know if I have cast or forged internals? I can't seem to find the year when they made the switch

I think the 454 and 502 Mag engines were forged, others were cast...........who really knows besides looking at the crank part #.......I opened up a 502 Mag MPI one time and found Manley H beam rods, these were typically in the 500 and 525 EFI engines

There should be a number on the block in front of the right cylinder head, there might be a tag on the right rear corner, some kind of number that you can search. If you're going to rebuild anyway, tear one down. It's not going to be cheap no matter what you do.

Year does not matter. Which engine you have does. There are several different Merc 454's. What does it EXACTLY say on the top of your engine???

It depends on your disposable cash and how long you intend to keep it. If its a long term boat for you but can't throw that kind of money at it all at once, start gathering parts, and when you pull the trigger on freshening, take the budget you have in mind for the rebuilds and double it.
If its not a long term boat for you, the superchargers will add zero value to the resale, maybe even scare away some buyers

Thank you for the info. After doing a little more thinking Im going to pass on the superchargers. This is my first boat and I already want something bigger so it doesn't make much sense of dumping crazy money into it at point.

You are way smarter than I was with my first boat
Actually and the next ones too!
