where to mount transducer on triton aluminum bass boat

Mounting a transducer on an aluminium boat is a crucial step in ensuring accurate and reliable sonar readings. Transducers are the key component of fish finders and depth sounders, and they work by emitting sonar waves that bounce off underwater objects and return to the device, providing valuable information about the water depth and presence of fish.

There are several options for mounting a transducer on an aluminium boat. One common method is to use a transom mount, which involves attaching the transducer to the back of the boat's hull above the waterline. It's important to ensure that there is no interference from strakes or other protrusions that could disrupt water flow and affect sonar readings. Another option is to drill holes and mount the transducer directly on the transom, using silicone or other sealing products to prevent leakage. Some people also use a transducer mounting plate or a piece of nylon or PVC board to attach the transducer without drilling holes in the hull.

Transom mounts are a popular option for aluminium boats as they are easy to install and remove. They are also a more affordable option compared to bow mount engines. Transom mounts are usually attached to the back of the boat's transom using a bracket and screws.

When mounting a transducer on an aluminium boat, it is important to consider the hull design. Aluminium boats typically require a different approach due to their hull construction. It is crucial to choose a location that ensures a clear and undisturbed flow of water. The transducer should be mounted above the waterline, and it is important to ensure there is no interference from strakes or other protrusions that could disrupt water flow and affect sonar readings.

  • Central Location: Aim to install the transducer as close to the centre line of the boat as possible, typically on the starboard (right) side due to the downward swing of the propeller.
  • Distance from Propeller: Ensure the transducer is at least 15 inches (38 cm) away from the propeller to avoid interference and potential damage.
  • Avoiding Propeller Path: Do not place the transducer in the path of the propeller, as this can cause cavitation and degrade boat performance, potentially damaging the propeller.
  • Steer Clear of Turbulence: Avoid mounting in areas downstream of strakes, struts, fittings, water intake or discharge ports, or anything else that creates air bubbles or turbulent water, as this can lead to inaccurate readings.
  • Orientation: Ensure the transducer is parallel to the waterline when the boat is in the water for consistent contact with the water and more accurate readings.
  • Avoiding Excessive Depth: Mounting the transducer too low increases drag, exposes it to debris, and can create turbulence that hinders performance.

To install a transom-mounted transducer, follow these steps:

  • Gather tools and materials: transducer, mounting hardware, drill, bits, marine sealant, screwdriver, wrench, tape, level, and marker.
  • Confirm the location: Recheck the transducer's position, ensuring it is away from any obstructions and in an area with minimal turbulence.
  • Mock setup: Temporarily place the transducer and bracket, marking the screw positions to ensure level alignment.
  • Drilling: Drill holes at the marked spots, using a drill bit slightly smaller than the mounting screws for a tight fit.
  • Apply sealant: Apply marine sealant to the holes to prevent water seepage into the transom.
  • Attach bracket: Align and screw in the bracket, keeping it loose for adjustments.
  • Adjust transducer: Slide in the transducer and align it parallel to the hull, ensuring it is submerged when the boat is at rest.
  • Tighten everything: Once everything is aligned, tighten the screws on the bracket and transducer.
  • Route cable: Route the transducer cable to the fishfinder display inside the boat, avoiding pinch points, and secure with clamps or ties.
  • Connect display: Attach the transducer to the display unit, ensuring a tight connection.
  • Test the setup: Test the transducer in shallow water before going deeper to ensure it is functioning correctly.
  • Final checks: Check that screws are tight, sealant is dry, and cables are secure.

By following these steps and considerations, you can ensure optimal performance and accurate readings from your transducer mounted on an aluminium boat using a transom mount.

Thru-Hull Transducers: These can be used on aluminium boats but require careful positioning to avoid interference

When it comes to mounting a transducer on an aluminium boat, it is important to consider the best location for optimal performance. The transducer is a critical component of your fish finder or depth sounder, sending and receiving signals to detect underwater objects and the depth of the water. Mounting it correctly can make a significant difference in the accuracy and clarity of the readings.

Thru-hull transducers can be used on aluminium boats, but careful positioning is required to avoid interference. Unlike fibreglass boats, where you can typically mount through-hull or shoot-through-the-hull transducers, aluminium boats usually require a different approach due to their hull construction.

A true thru-hull transducer is one that you drill a hole for and mount through the hull. These work fine on aluminium boats. However, it is important to note that the installation process for thru-hull transducers can be more complex and time-consuming. It involves drilling a hole in the hull and ensuring proper sealing to prevent leaks.

When installing a thru-hull transducer on an aluminium boat, it is recommended to use a plastic transducer mount to avoid potential electrolysis problems. Mounting the transducer between two ribs of the boat usually works best. It is also important to ensure that the chosen location doesn't interfere with the boat's trailer and is at least one foot away from the engine's lower unit.

Another factor to consider is propeller wash and water turbulence caused by your outboard motor. Ideally, you should mount the transducer in a location that offers a clear and undisturbed flow of water.

Additionally, when mounting a thru-hull transducer, it is crucial to use the proper adhesive or sealant. Marine-grade adhesive or silicone sealant can be used to secure the transducer to the hull. It is also important to ensure that any cables or wiring associated with the transducer are securely fastened to prevent them from snagging or getting damaged.

By carefully positioning and installing your thru-hull transducer, you can achieve optimal performance and accuracy from your fish finder or depth sounder on your aluminium boat.

Shoot-Through-The-Hull Transducers: Unlike thru-hull, these are suitable for fibreglass boats

When it comes to mounting a transducer on a fibreglass boat, you can opt for a through-hull or shoot-through-the-hull transducer. Unlike thru-hull transducers, shoot-through-the-hull transducers are suitable for fibreglass boats as they can be mounted inside the hull without drilling any holes. This is possible because fibreglass has similar sonar characteristics as water, allowing the sonar signal to pass through with minimal loss.

However, it's important to note that this method will not work for Side Imaging transducers. Additionally, the hull of the boat must be single-layer construction and should not contain any foam or air pockets in the lamination, as these can interfere with the sonar signal. To ensure a strong connection, two-part slow-cure epoxy is required to glue the transducer in place.

When choosing a location for your shoot-through-the-hull transducer, it's important to select an area that is free of any liners, coring, or double-hull construction. You may need to remove the inside layer and coring and build up glass before installing the transducer. The transducer should be glued directly to the hull, ensuring that it is secure and does not move.

Keep in mind that you may experience a decrease in clarity and functionality when using a shoot-through-the-hull transducer compared to a traditional transom mount. However, with experimentation, high-speed operation comparable to transom mounting can be achieved.
