Need new MMDC gauge computer


Recommended Posts

My MMDC gauge computer went belly up on my 07 23 LSV. The part number is 7021-00009-01. Does anyone happen to have one or know where I can get one? It is Saturday so Medallion is not open but will call them Monday. I am sure they want an arm and a leg for it so I figured I would ask the crew. Thanks.

Try bakesonline.com  Be prepared for delays in production (chip shortage and they are all custom built with 30 day waranty!) and SERIOUS sticker shock.  Expect to pay north of a grand for one.  Frankly, if you can do it, just replace all the gauges for less from skiboatpartsonline.com

It isn't the gauges it says it lost connection with the ECU. I did check bakes no luck.

No - I mean remove the MMDC completely and replace the gauges for less than the cost of a new prone-to-failure IME  black box.

Oh I see what you are saying. Might be a possibility

FYI, that era of MDC (unless you have the mini) will run you around $1500 - 30 day warranty.

Yeah that is what I hear. That sucks.

Fortunately for me it is a mini but now I just need to find one. From what I have seen the price should be less then $150.

Lots of this version. https://www.marine-surplus.com/product/medallion-mini-mmdc-module-7021-00007-01/  And cheap - but you will have to call MedallionIS to see if it will work.  Otherwise I doubt you will find a NIB one and may be forced to custom order which s likely to cost a small fortune, even for a mini.

I will be interested to get Medallion on the phone tomorrow and see what my options are.

I was able to order one from Medallion. The price wasn't bad. Thanks for all the advice.

Sorry for the late reply I paid $308 shipped. Took 3 weeks to get they had to build a new one. I will hopefully be installing it tomorrow I sure hope it fixes my issues.

I installed the new MMDC and it appears I have all functionality back. Hopefully this continues. Thanks to all that helped.
