Man... I just saw your amazon link.... Wish I saw it before... I purchased many similar items while doing my refurbish. I will get you next one... I have another one I may tackle in the next year.
Great video, exactly what I was looking for. I'm working on replacing all my gauges and the wiring was pretty intimidating. Your explanation makes it easy to understand! Thank you!
Thanks for watching! We’re here to break things down so that all DIY folks can tackle these projects at home without being afraid of the task. Happy it helped you out!
Wow, idk why I was so scared to try and tackle this myself, ALOT easier than it looks! Thank you so much for this, plain simple and to the point! 👏 bravo
It’s straight forward once you understand the posts on the gauges, the colors of the wires, and where the gauges will get power, ground, and signal from!!
@@brod12313 I’ve never installed a dual helm setup. I would reach out to a local dealer or service center used to dealing with dual helms and ask them. I’m not sure if you can just piggy back off the signal wires or not. I’ll do a little research and see if I can find out more.
@@tomspontoons yeah, I was thinking I could piggyback everything too, but I also thought gauges were complicated and hard to mess with too lol then I saw ur awesome video 👌 thanks again
Great video, as a fellow TH-camr, your presentation and information was complete and well done! Really helped me in my replacement of gauges on our boat!
Thank you so much! I learn all sorts of stuff from other channels that provide great information and detail, so I definitely want to provide something similar. Thanks for watching!
I have a 2006 Yamaha 90 2 stroke and the gauges were replaced but not the harness. This video is great at explaining the mess that's under the dash!!! On mine I see two small fuses on the yellow wires but did not see them on your wiring. did you put fuses in and if you did where? Thanks a milllion!
Usually the only fuses run for gauges will be for a depth gauge or fish finder powered off the key on power. That’s the only time I’ve encountered fuses on a gauge panel. Otherwise outboard associated fuses are on the engine.
@@BoondockingCajunstyle Great question! It does have running/navigation lights. I’ve seen gauge backlights wired both ways, even from the factory. I was always taught to wire them into the key switch, that way they’re on when they’re needed…when the engine is running. No wrong way to do it as long as you can see them at night!!
Great video - thank you! Two questions: Is there some basis for deciding which gauge to start with to receive power directly from the ignition? Is there a reason why the power is jumped from the tach to the speedometer and ends there, whereas there is a second jumper from the tach. to the volt-meter, which is jumped to the fuel gauge?
Thanks for watching. The power and ground can come in to any of the gauges to start and jump from there in any order out to other gauges. It’s honestly personal preference and however someone would want to keep things in order.
Yes, but be careful to make sure you have the gasket lined up and snug to ensure it doesn’t get water in. As far as I know you can add a sending unit to any tank, although it’s not always practical if it’s much smaller than 12 gallons.
There’s a lead for gauges worked into the 10 pin main harness for the engine that runs from the motor to the key switch, shift/throttle, and under-dash accessories. I wired this to be spliced into that portion of the main harness. Ultimately, the colors will match up to the gauge leads for power and signals. Let me know if that makes sense.
I use Moeller brand tanks whenever installing new on a boat. I'm not sure how or if you can wire two tanks to a single gauge. I'm sure there are gauges with two read-outs on one gauge face so you'd connect each tank's ground and sending wire to be able to get a reading for both tanks. Otherwise we've done one boat where we wired in two separate gauges to allow for two tanks.
Where Can I find a wiring diagram for a Robalo R160? Has a Yamaha F70LA OB Would like to install a couple voltage gauges. One for each set of batteries. Your expertise is greatly appreciated.
I’m far from an expert on that style of boat. I’d check with a Robalo dealer for contact them directly to figure out where those sets of batteries come into the console. Otherwise you could pull wire from each battery to hardwire a gauge set in off of a switch for each battery set.
I try to use marine grade whenever possible…copper tinned coated wire. Anything else may just not last as long before corrosion sets in. However, if it’s protected from chaffing and is sealed up at connections it should last a long time even if you used trailer wire!!
The seperate like 2 ro 4 wire harnes that says gauges at 1 end and to engine on the other end where does that go and the pigtails on the 703 yamaha control the up and down tilt where do they go from the 703 control
I'm not exactly sure what wires you're referring to. The trim and tilt wires should be integrated into the 10 pin ignition harness that goes from the control box and plugs into the engine. We have a full video of installing a 703 control box on our channel that might help answer some questions!
Never ground to the frame of the boat. The ground needs to make its way back to the negative post of the battery whether it’s through a ground buss bar, a common negative lead at the helm, or the motor ignition harness. With gauges, you’re wiring through the ignition harness, so using the ground that’s included in that bundle of wires is the best option.
@@tomspontoons thank you for the info. This Yamaha control box has a lot of different color wires in it. Very confusing looking at it being can’t find much info on what wires are what
@@sheabourne9428 There are some Outboard Ignition Harness Wiring charts out there which tell you what colors do what. I think I've shown the one I use in some videos where you can pause it and screen shot it to get what you need from it.
Double check that the green wire (tach signal wire) is attached at the gauge as well as where it’s attached to the ignition harness. Sometimes connections can come loose or corrode. Then double check that you’re getting power to the gauge from the yellow wire (key on power) and that the ground is connected. Beyond that I’d wonder if the gauge quit working and needs to be replaced.

I am rebuilding a Lyman and this was a perfect explanation for how to put in the instruments. Thank you.
What a cool project!! I’m so glad it helped you, we’re always hoping our videos can be applied well beyond the Pontoon world!

Just what the lame-o ordered. I feel like I can do this now! Thanks Tom.
You’ve got this!! Let me know if you have questions when you tackle your gauges!
looks good. Will this boat have running lights? Would it be better to tie the back light into running light switch?

If I don’t have fuel sending units do I have to drill the holes to install senders?
Yes, but be careful to make sure you have the gasket lined up and snug to ensure it doesn’t get water in. As far as I know you can add a sending unit to any tank, although it’s not always practical if it’s much smaller than 12 gallons.
Thanks Tom your video really helped. Did you have to use the Yamaha AGI to get these gauges to work or were the connections taken from the bus wires?
There’s a lead for gauges worked into the 10 pin main harness for the engine that runs from the motor to the key switch, shift/throttle, and under-dash accessories. I wired this to be spliced into that portion of the main harness. Ultimately, the colors will match up to the gauge leads for power and signals. Let me know if that makes sense.
Where do you get fuel tank kits? How would you wire two tanks to a gauge?
I use Moeller brand tanks whenever installing new on a boat. I'm not sure how or if you can wire two tanks to a single gauge. I'm sure there are gauges with two read-outs on one gauge face so you'd connect each tank's ground and sending wire to be able to get a reading for both tanks.

Hi Tom, as usual a well informed, well delivered presentation thanks mate😁🌟🌈🇦🇺

Where Can I find a wiring diagram for a Robalo R160? Has a Yamaha F70LA OB
Would like to install a couple voltage gauges. One for each set of batteries. Your
expertise is greatly appreciated.
I’m far from an expert on that style of boat. I’d check with a Robalo dealer for contact them directly to figure out where those sets of batteries come into the console. Otherwise you could pull wire from each battery to hardwire a gauge set in off of a switch for each battery set.
Do you need any special type of wiring (like a marine wire)? or can i use regular like trailer wire 14awg?
I try to use marine grade whenever possible…copper tinned coated wire. Anything else may just not last as long before corrosion sets in. However, if it’s protected from chaffing and is sealed up at connections it should last a long time even if you used trailer wire!!

What's wrong if I'm getting no signal on my Yamaha
Did you have a tach that was working but now quit? Or wiring in a new one from scratch?
I'm getting no tachometer signal
Double check that the green wire (tach signal wire) is attached at the gauge as well as where it’s attached to the ignition harness. Sometimes connections can come loose or corrode. Then double check that you’re getting power to the gauge from the yellow wire (key on power) and that the ground is connected.
