I have just had our local Nautique dealer replace all my gauges on my 2007 220 nautique with the Faria Gateway Conversion Kit. I presumed this would also fix the depth finder (the guage is included in the kit) along with the gauges that didn't work. It didn't. So, i am thinking the transducer must be replaced, now. My questions are: 1) are there instructions for the replacement of the transducer? and 2) is this a DIY project that is not to complicated but will just take time? Thanks.
