Repair for Dead Gauges on 2003-2006 Nautiques Caused by Bad Faria Gateway

[TechBeer]

Brucetheshark Not sure if you are still looking at this but I can certainly fix your individual gauges that don't work. The gateway is blamed for a lot of issues but 90%+ of issues are a flaw in the individual gauges which is easily repairable. Especially for a gateway without the pitot tubes. PM me if you want to go into more detail.

I agree that the engine ECU data is likely just a CAN J1932 protocol. However the output of the gateway is a 2 wire proprietary that is not a simple CAN bus. If the data is available on the LCD screen(s) but not on the smaller gauges, the problem is with the gauge, not the gateway. If you get garbled data on the LCD and/or the nav lights don't work and/or the needle doesn't move this is an indication of a bad gauge (fixable).

If you want to keep the original look of your Nautique I suggest fixing the gauges that go bad.

My GW Box CAN Msg to the dash is likely corrupt, or the Speedo & Tach LCDs both went bad at the same time. When I started the last ride of the year to pull the boat out this fall, both the LCDs had minimal segments working, and the Speedo went into alarm mode. When I bought the boat in 2020 the Oil & Temp gauges didn't work, and continued to not work when I replaced them.

Interesting. I've never seen a situation where 2 of the small gauges worked and the gateway had an issue. I believe Temp actually come from the engine ECU via the CAN interface. Oil pressure comes from a separate sending unit, at least up to 2005. Not sure on the larger gauges but garbled messages on the LCD is a classic symptom of gauge failure.

If you have some down time I would be happy to test all 4 gauges in my lab. If they are all functional I would just ship them back to you. PM me if you are interested.

2006 is a one year only application for pcm engines as it is a MEFI/DBW configuration. gateway conversion kits are nothing more than installing a analog set of gauges and a over complicated wire harness. keep in mind all pcm engines generate a analog signal through their ECM's.

TechBeer: is this a hobby to repair gauges or do you do this as a job? would like more info on what you do repair or can repair? we get a lot of calls at DIM for many of the gauge failures of many manufacturer boats. you can direct email me to support@nautiquparts.com

Merry Christmas

Hi Jody. Sent you an email but I assume it's really support@nautiqueparts.com??

Let me preface this with I copied and pasted from what I posted on the Nautique Boat Owners group, so my apologies that it’s explained a little more than this group needs. Does anyone in here have experience with both kits an have a preference? I have my own pros and cons for each kit looking int them, but never dealt with one hands on. This is for a 2006 SV-211.

Looking for input from people who have done either of the available gateway conversion kits for mid 2000s Nautique’s. Bonus points if you’ve had experience with both kits as your insight would be very valuable. I want to know which product seems to function the best and integrated the most seamlessly. The price difference in kits isn’t enough to sway me one way or another.

SP-14-1246 - This is the kit NautiqueParts.com offers. It has been around for quite a few years, but had several different changes throughout the years. I know the most recent update was 2022 or 2023 but haven’t read much feedback on it since that update. It appears all gauges match now, they didn’t for a while, let me know if you know otherwise. I like this kit because it appears to keep all factory functions in the allotted factory dash holes. No problem leaving stargazer PP in place and powering it. It does seem to be a bit more complicated to install, but if it gives me a better finished product, that is fine.

TRD-2001-CC - This is the kit that Ron Tanis developed and sells on skiboatpartsonline.com. A few years ago he switched from Faria gauges to his own gauges and they have connectors to plug and play with factory wiring. This kit easier to install from what I’ve read. The kits appears very nice and is offered in black or white. I’m confident in quality coming out of Ron’s shop with his name on it. However, the downfall to this kit is you lose the depth/temp gauge, in the factory holes anyways. He says an additional gauge can be ordered and pigtail added on his harness to regain those functions, but the gauge they sent me a link to was a generic Sierra gauge that was ugly and only appears to do depth alone. I’m waiting for a response on if they offer a different gauge that does both or if they can adapt the Faria gauge offering that Nautique uses in their kit to do depth and temp. I’m not willing to lose depth or have a janky looking add on gauge, so hoping there is a good option for this.

Ultimately, I like both kits for their own reasons, so I need some real world feedback. I wanted to go with TRD because I’ve had great luck with Ron and his expertise is invaluable when it comes to all things boats. Maybe I just need to call him on Monday to get for sure answers to my questions.
