Bad ECU 01 Merc 350 Mag MPI

[lakepatrol]

The jokers at Merc want $2400 for a new ECU for my 01 Merc 350. I need a link to another EFI source or Carb conversion. Can anyone help?

There is no other EFI source. If you need a specific ECU then you need a specific ECU. First you need to know if you have a MEFI 4, a MEFI 5, or a 555 PCM.
From there you can see if somebody on the net is selling them cheap. It's not a diagnoses you want to screw up though, as you can't return ECU's.

If you want to go the other way. You need a Delco voyager distributor. An intake manifold, a carb, you'll have to look at the existing engine side fuel system and convert it as necessary.

Just a new manifold, carb, and ignition system not including any labor is going to put you close to the cost of a new ECU, and your going backwards. I'd be more curious as to why you need a new ecu in the first place.

Welcome to the world of boating, where the phrase "gotta pay to play" was invented! And how do you know yours is bad?

I've got a 2000 305 merc. The sea ray dealer told me $1500 for a ECU. Can't see why yours is worth another grand. Keep shopping.
