Installing an External Transducer

Your trolling motor may come with a Mega Side and Down Imaging (MSI), Mega Down Imaging (MDI), Dual Spectrum CHIRP (DSC), or a Universal Sonar 2 (US2) transducer built into the lower unit. The built-in transducer may interfere with mounting an external transducer, depending on the size of the external transducer. Also, having 2 transducers that close to each other, may cause interference.
*Note: When installing an external transducer on an Ulterra, Riptide Ulterra or Riptide Instinct QUEST, you need to be careful that the transducer cable does not get pinched when the motor is stowed and deployed.

Mounting an External Transducer on a Non-Auto Stow/Deploy Motor

1. Mount the External Transducer according to directions provided with the transducer.
2. Leave enough slack in the Transducer Cable between the Lower Unit and Control Head to allow the motor to properly stow and deploy.
3. Use two tie wrap cables to secure the Transducer Cable to the Shaft just below the Control Head.
4. Run the Transducer Cable through the Coil Cord to the power supply.
