I am installing a SONAR on my SPORT 15. How do I run the wire from the unit to the transducer on the transom? Do I drill through the transom? Or should I just loop it over the transom? What is the preferred method. Please direct me to any links that might help too. Thanks! |

I would start with this link - http://continuouswave.com/whaler/reference/sonarTransducer.html |

Thanks. [The reference article] looks like it is a well thought out discussion. I have one more question: if I loop [the cable from the transducer to the SONAR] over the transom, with what do I attach the loose wire to the transom? Another question, do I directly link to the battery or the fuse box? The unit I have already has a 3-amp in-line fuse. Thanks again. |

I would use the small cable stays that are available from any marine chandlery. They are white/offwhite plastic and take one screw. Pre-drill a shallow hole in the transom, apply silicone/sealant and install the screw and cable tie. Do this in a straight line up the transom to the top and then blend in the wire with the rigging for the engine. I'd attach the power through your fuse block with an appropriate sided fuse, if you have the room in your fuse block. |

I wouldn't blend the transducer cable into the engine wiring until the engine wiring was pretty close to where it ducks under the deck. Remember that the engines swings port and starboard, the transducer does not. You probably have an Acc switch on your sport 15. I'd wire Don't use anything you bought at the hardware store or auto

You can use nylon cable clamps of the appropriate size to secure cable to a surface. You can also use stainless steel clamps if you prefer. You can find these sorts of electrical wiring accessories for marine use at most any place that sells marine electronics and electrical accessories. They are a good way to secure the cable from the transducer to the transom. The power demands of a modern solid-state SONAR are modest so there is no particular reason to wire its power leads directly to the primary distribution wiring or the battery itself on your boat. You can connect the SONAR unit to a secondary battery distribution branch circuit. (Moderator's note: Rather than consolidate a wide variety of questions about boat electrical and electronic topics into a single thread, please begin a new thread when you begin a different topic or have a new question not related to the installation of your SONAR.) |

Woooooooo Nellie, no.
OK, you can run the transducer cable in through the transom drain or over the transom. Go to an auto parts store and purchase clear vinyl tape used for seat repair. It will adhere the cable at several locations just fine while testing. Since I do not have a good picture of your boat in my head I will not say what to do after testing, most likely you will drill a hole and route it through the rigging tunnel.
Also, I recommend a KING Starboard or similar material to make a transducer mouting plate on the transom. Many boat shops have generic ones but I custom made mine. |
