Edelbrock Pro-Flo XT EFI system BBC in a marine application

Has anyone tried this as a marine application? Rebuilding the 502 in my 96 Baja 252 and it has a standard 502 Mag MPI setup with a MEFI 1 ecu. I am looking at my induction options and I came across someone running this on a 502. I tried calling Edelbrock but after being on hold with tech support for over an hour I gave up.

I know it requires a WB which I know don't typically last in a marine application but I will replace the O2 each season if the system will work.

Do you want to buy a product where the tech line keeps you on hold for an hour?

Honestly this day and age I'm not sure of one out there that does not. I prefer Holley honestly but I wanted to know if anyone has experience with this system.

No experience but I think you’ll be better with something from Holley. If you wanted a better way of controlling everything, a Holley ecm can be made to work with the mpi sensors. Adding the O2 sensor is not hard and can be made to last. Having a knock sensor is good too. All can be done with the Holley.

Holley ECM is approved for marine use and there are many sources of information online to help troubleshoot issues,
and as said above you can use just the ECM and harness on your existing system.

I have had great service from Holley's tech line.

I don't know why this mantra keeps coming up. Yes SOME people have issues with wide band lasting, but I think placement is key. I run mine full time for the last 12 years. Replaced it once.

Agree with above...holley makes a very similar if not the same setup and I would hands down go that route. Then swap to their either hyperspark or CNP(coil near plug) ignition and have a damn near bulletproof setup that's easy to work with and tune...just my thoughts.

And to add....I'm no expert on induction types however I believe a different type of intake may work better in the marine world...like a "standard" 4 bbl type intake that's port injected with a 4 bbl throttle body on top...holley makes one of those as well...just a thought.

Holley offers this but with a single plane, not sure for a boat a single plane is ideal for low end tq. I agree Holley is superior over edelbrock and almost twice the price too.

Could go with a sniper kit and get your own dual plane or whatever intake you choose is an option as well....that's a HP kit I believe you linked and they are pricey....however coming form someone that is in the process of replacing the entire EFI system because I went the cheaper route initially...spend the money up front and do it once!! You won't be sorry trust me hahaha
