If you have all your bases covered and come prepared with everything, right down to the last detail, nothing can stop you from walking away from your fishing trip with a giant catch. One sure shot way in which you are be prepared for catching good fish involves installing a fish finder. However, if you have a fiberglass boat, you may be unsure about how to go about with this installation. There is no need to worry; here is how to install a fish finder on a fiberglass boat.
Create a strong basis
You need to first set the right foundation. To do this:
- Understand where you want to place your fish finder. Know how much free space you need and see that you pick a place that is easy to get to from where you are sitting at the cockpit.
- Measure thoroughly, cut carefully and drill once. Keeping the drill at a good speed helps you drill evenly.
- Wiring helps you gain access to the fish finder more accurately. See if holes are already present. If you can’t find any, be sure to drill one extra hole at the back of the mount.
You can feed the power leads with the help of the exit hole you just drilled. Make sure there is ample slack on the plug and after every one and a half feet, seal the wires. Do this with the help of tie wraps.
Installing and placing the fish finder
Have the right place in mind for the transducer bracket. Hold it against the transom and until you get the best position, move it around. Make a marking of where the mounting holes of the bracket end up. Run the wiring through the dash and coil and extra line inside. Secure the wire with clamps and see that you keep the engine wiring, VHF cable and transducer wire away from each other. Drill holes at the markings made and use a sealant to coat clean insides of the transom holes and screws. Screw the mount in place.

Use a clamshell to seal the wiring hole you previously drilled. Then finish all of the connections and secure the fish finder to its chosen spot. You can always check out the manufacturer’s manuals to get a better understanding of things.
There you go, now that you are aware of how to install a fish finder on a fiberglass boat, go ahead and do the needful.
