ECM -Engine control Module ....HELP! I need a New One

[RockyMtnErik]

We have a 97 Maxum 3000. one of our engine control modules ECM is out. we went through several other sensors and relays and finally tried switching the ECM from the other engine and it fired right up.

ANY RECOMMENDATIONS FOR A NEW, REBUILT OR REPUTABLE USED ONE?

Mercruiser 350 EFI with throttle body.

ECM by Delco Electronics
Model #: 16234539

I can get similar from auto parts store but they do not have preprogrammed. Usually about $120-150 after core trade in

Does anyone know where to get them other than used with no warranty off of ebay or at my marine suppy which is stupid expensive at $1800. Really!

An automotive one will not be programmed correctly for marine application. A used one or two as a spare is your best bet

They may have used ones sitting around. Or you can buy 2 new ones for less than the price posted above.

I had them tune mine and was really happy.
