I need some help on finding a mefi 3 or 4 for a 8.1 , I spoke with a few different people regarding the right controller , I found alot of them for the 350 or 502 ram jet but I was told they are different and will not work . I would hate to purchased this thru mercruiser because of their prices and can't find many sources at reasonable prices. Any help would be appreciated . Thanks Jeff

The 8.1 does'nt use the Delco Mefi, it has Mercury's own box. For a while it looked like Edelbrock was going to sell it to the aftermarket but I'm not sure if the deal is live.

Find a Volvo, Crusader or Pleasurecraft dealer. They run a Mefi 4 computer on their version of the 8.1. GM does not use Mercruisers system, so any engine marinizer other than Merc will have what you need.
