Im having some gauge issues on my '02 Maristar 230. Ive lost my fuel gauge (replaced sender, not the issue) and most recently the speedometer. What is preventing me from installing a gps speedo and using tried and true mechanical marine gauges and ditching the mdc/mastercraft stuff?

Im pretty sure the medallion gauges are no longer available, other than a full set from gls for almost $800.

I'd look on ebay for single gauges.

There actually seems to be a ton of options for you from a gauge perspective. The problem I see is that the most likely cause to your problem is going to be the MDC which is where the dollars are going to be. Switching over to actual gauges will most likely require new sending units and wiring to the dash. Not sure how that would effect the engine control or other features built into the system such as safe mode and low battery functions.

any ideas if newer gauges will work with a older mdc?

Good question. If it's like most electronic projects I've done the answer would be no. One way to find out, try getting in contact with the source at Medallion.....

I tried calling them yesterday.. I dont think they have living people working there as I got a machine runaround and sent to several voice mail boxes.. Go figure!

That would be par for the course these days. Throw a Email at them and see what happens.

You might also want to check with your dealer. Mine is pretty good with working with the local folk such as myself. They've always been very helpful. Of course I been buying gear from them for the past 10 years from them so that may help my cause.
