Install Transducer and cable

[rcurran]

I am ready to Install a Garmin Striker Fishfinder and would like some advice. Tell me what you think. I plan to mount the transducer on the right starboard Poon behind the ladder on the factory bracket.
Where is a good place to look to run the transducer cable? Since i don't want to follow exisiting power cables (to avoid interference). Some installs seem to stay on the outside of the console. Display is attached to the rail.
Others use a cup holder to mount the display unit. In that case the cable would need a route into the space beneath the con sole. Ideas would be appreciated on what people have done.

2017 23RCW. I Replaced my old, original Garmin with a new larger screen which required a new transducer, so I made a blank to fill the old helm-hole (then put a hole in that and a “hood” to route the cable to the new Garmin. New Garmin is mounted on the right of the helm in an otherwise unused area so it doesn’t block anything.

The transducer is on the port toon, but the wiring is essentially the same I think. I’m not sure if it is easier from helm to stern or stern to helm - I did the latter and wasn’t about to do it a second time! Basically it is a lot of fishing of the transducer wire. Start by making sure you have enough length - if not, buy the extension, securly attach it and add a wrap or two of waterproof tape. This is mainly so you don’t pull it apart while fishing it through.

Above my toons at the stern there are some holes so I routed the cable through one of those and then it just lays on top of the toon to the helm. I was able to get a hangar in the space between the toon and the side pieces, so didn’t have to remove those. Just slowly fish the cable forward until it was under the helm. Inside the helm, on my boat there is a boot with a bunch of cables running through (helm to under the deck). I loosened the boot (I think it had a large zip tie, which I later replaced), then sent a wire down. I was able to fetch that wire and the transducer cable from the side of the boat and wrap them together, then pull up int the helm. Finally, secure everything under the helm and route to the Garmin along with its other wires (which also are connected under the helm).

It is a “fiddly” job but not hard; some points along the way it helps to have an assist.

I would rate this a basic vocabulary job, few extra words needed to complete.

My factory Garmin was also mounted on the port toon which is odd because you typically want them mounted to the starboard side due to prop wash from a std rotation outboard. Mine was routed along with the factory underwater light wiring and zip tied once it went under the wave shield etc.

Transducer cables are fully shielded with aluminum foil inside the jacketed cable, so it will reduce any interference you might see from other power cables. But I agree, its best practice to not run them together. if you do end up having "lines" of interference in your screen, you can always add a "snap ferrule" over the cable just before

mine was indash mounted and it was also ziptied to all the inside console wire harness bundle. So I think your chance of getting interference is pretty low to nil.
