170 Montauk help with electronics instalation

Well, I am STILL in the process of instaling the electronics, Garmin 240 blue fishfinder, Garmin 162 GPS map and Atlantis hadheld VHF (I admit every free time I had since I got the boat I take it out on the lake!). I had to go with the RAM mounts for space and 360 degree visability for the Garmins. I chose the RAM 111 due to the longer bracket and will be closer to my myopic eyes. Now I need help with ideas for passing the cables from the back of the units to the inside of the CC, the plug is about 1/2 inch thick each. I hope to pass them both throught the same opening aft of the RAM mounts. Any ideas how to make the opening looks good other than seal it with silicon. Thanks, Sam

Hi Sam, you can probably get away with drilling a 3/4 inch hole with a hole saw. Drill from both sides using tape on top to eliminate most splintering. Pass one cord through and then the second. Use a Perko clam shell (West Marine or Boaters World) over the hole. If you want you can probably put some silicone in the clam shell, I did not.
PS: after drilling the hole either paint the drilled portion with epoxy or rub some type of water proof caulking in the cut area to waterproof it...Jim

Thanks Jim, that would look great, and with the slight angle of the surface of the CC, it will be difficult for water to go up under the shell. Thanks, Sam

I used the Perko method and it turned out great. I used a hole saw on the top surface and installed the vent clam shell over the opening. I then filled the drilled opening with the cables through it with life caulk just for good measure. I used the same method for the Garmin 188C antenna cable on the front of the console for the cable entry point. I took out my 2004 170 today in Lake Michigan and the water temp was 39.6 degrees. Still had a good time.

Just a some notes about the use of the clam shell:
*Always orient the opening flange of the clam shell to prevent kinking in the wiring.

Can you describe the routing and difficulty of the process of routing the transducer wiring from the transom to the CC?
How did you mount the transducer?
Why did you not choose a combination unit for gps and sonor fish finder?
Thanks for your help!

Better than the clamshell is the cable cap made just for this application. It is flat, round, and about 1-2" in diameter and held down by three screws. Has a cut out for the cable to exit. Put it down with silicone sealer under the cap, and no water is going to get by. They are sold at West Marine and other stores. I think the mfg is "Smittys"

If you use a clam shell, cut a piece of inner tube the same
size as the foot print of the clamshell. Put it between the
wire and the clam shell. It will help keep a lot of water

Another suggestion is to use a 3/4" nylon thru-hull fitting like used for bilge pump discharge. The 3/4" thru-hull requires a 1" diameter hole be drilled and has a 1/2"+ inside diameter. This makes a neat looking installation and the cabling can still be moved.

sumnerdav, I used a piece of 1 inch thick by approx. 4x4 inch piece of starboard material on the transom for the transducer mount. I attached it with two stainless screws and 5200 caulk/adhesive applied to the transom side of it. This starboard material can be shaped, filed ,sanded etc. to match the transom angle and bottom shape. The transducer is then mounted to the starboard using the supplied screws. If the transducer ever needs to be replaced in the future, there are no more screws needed in the transom, just into the board material. As far as routing the transducer in a 2004 170, a string is supplied in the cable chase from the transom to the console. This works out great to pull the wires. I chose the Garmin 188C combination color GPS/Plotter. The GPS antenna was mounted on the fore grab rail on the windshield. The unit works great and is easy to mount. Hope this helps.

Thanks for all the good tips, I went with separate units because it is less distracting for me especialy when I am trolling. It could be easier if repairs are needed. I think it is a personal preference, whichever works for you. For the limited space on the 170, one combined unit might be the way to go for the majority. I'll have to install separate sensors on the transom (sounder and speed) I like the idea of the starboard plate. As mentioned before, the string supplied by BW makes it easy to pull the cable out, I ran it from the bilge well, did anybody ran it out from the motor harness? Thanks, sam

Thanks for the suggestions.
What is starboard material? Please excuse my ignorance. Where can starboard material be purchased?
I think you made a very good choice in the Garmin 188C.

Sumnerdav, you can buy white starboard "Marine lumber" from any boating store, like Westmarine or Boatersworldfor about $20 fo a 1/2"x 12"X 27". There is black Starlite brand available too. Sam
