Finding the place where to mount transducer on pontoon boats
Deciding exactly where to mount transducer on pontoon wood logs could be a real head ache if you've never ever done it before. Unlike a standard V-hull boat where you just discover the lowest point on the transom plus call it the day, pontoons have got two (or three) big metal pipes that throw the lot of pockets and "dirty" drinking water to the mix. When you put that will little plastic messfühler in the wrong spot, your extravagant fish finder is going to show only static as quickly as you force the throttle previous a crawl.
It's one associated with those projects that feels high-stakes due to the fact nobody likes the particular idea of going holes into their boat, even when it's just into a group. But when you understand how the water flows around these aluminum logs, it's actually pretty simple. You just need to discover the "cleanest" drinking water possible therefore the sonar signal can perform the thing without disturbance.
Search for the factory bracket very first
Before you go buying extra hardware or even getting creative along with a drill, check out the back of your logs. Many modern pontoons have a mounting bracket already welded onto the trailing edge of the starboard (right) log. Manufacturers know you're going to want a depth finder, so that they usually save you the problem of figuring out the mounting surface yourself.
If you possess one of these brackets, that's almost certainly where to mount transducer on pontoon setups. It's positioned there regarding a reason. Usually, it's tucked just far enough aside from the motor to avoid electric interference and brace wash, but close up enough to the underside of the log to stay submerged. If your boat is definitely older and doesn't possess a bracket, you'll likely need to pick-up an auto aftermarket stainless-steel or aluminium bracket that a person can attach to the log.
Starboard side is usually the particular winner
Generally there is a bit of a controversy in the sailing world about which side is most effective, however for about 90% of pontoon owners, the starboard record may be the way to go. The major reason for this particular comes down to just how your propeller moves. Most outboard engines possess a right-hand rotator, meaning the blades are pushing drinking water downward on the starboard side.
On the particular port (left) side, the propeller will be moving upward, which usually tends to stop up more bubbles and turbulence. Considering that transducers hate bubbles—they perform like a walls for sonar waves—putting your sensor on the starboard log offers you a much better chance of obtaining a clear reading when you're traveling at higher rates of speed. It's an easy "path of minimum resistance" type of factor.
Having the height just right
This is where a lot of people mess up. If the transducer is too high, it'll come away of the water once the boat planes out or strikes a wake, and you'll lose your own signal. If it's lacking, it'll create a massive "rooster tail" of drinking water spraying in the back of your boat, and you run a higher risk of hitting an immersed stump or stone and snapping the mount quickly.
The general guideline is to possess the bottom of the transducer sitting about a good eighth of an inch below the bottom of the pontoon log. You desire it just deep good enough to remain in "solid" water, although not so deep that it's acting like a rudder.
Whenever you're taking a look at it from behind, the transducer must be degree. However, just a little technique many seasoned anglers use is to tilt the rear associated with the transducer lower just a tiny bit—maybe a few of degrees. This can help ensure that the face from the messfühler stays in touch with soft water instead of catching air pockets that roll off the bottom part of the log.
Avoiding the "dirty water" zones
The biggest enemy of a clear sonar display screen is turbulence. On a pontoon, turbulence comes from a couple of places. First, there are the strakes—those lengthy fins on the underside of the records that help the boat lift plus turn. If your transducer is sitting straight behind a strake, the water hitting it is heading to be full of air bubbles. It'll seem like snow on a well used TV screen.
You also want to stay away through the motor's reduced unit. If you mount the transducer as well close to the engine, the vibrations and the electrical noise from the motor can mess with the transmission. Plus, if it's too close to the prop, the particular water being drawn into the blades will create a vacuum effect that ruins your reading through. Keeping it on the outer fifty percent of the log's rear surface is generally the sweet place where to mount transducer on pontoon hulls.
Dealing with the wiring
Once you've obtained the physical mount figured out, you've got to deal with the cable connection. This is the part that testing most people's tolerance. You don't desire the wire simply flapping around within the wind or even dangling close to the water. Most people run the cable in the bracket and after that across the cross-channels of the pontoon's framework.
Use a lot of zip connections, but don't draw them so tight that you touch the wire. Sonar cables are really pretty sensitive, and a hard twist or a smashed internal wire can ruin the entire unit. Also, consider to maintain the transducer cable far from the particular main engine power wires if a person can. Running all of them parallel to every other for lengthy distances can trigger "noise" on your screen every period you rev the particular engine.
The "No-Drill" alternative
If the idea of putting screws into your boat makes you break out in a cold sweat, a person aren't alone. Right now there are mounting blocks made of high-density polyethylene (basically elegant plastic) that a person can epoxy to the log or maybe the bracket. You glue the block to the boat, allow it to cure, and then screw your transducer to the block. That will way, should you ever alter your fish finder or move points around, you're just putting holes inside a replaceable piece of plastic rather compared to the boat by itself. It's a godsend for resale worth, too.
Screening it out on the water
Don't fully tighten everything down till you've actually used the boat out there for a rewrite. Bring a wrench with you to the lake. Begin slow and see if you're getting a good depth reading. If it looks good, slowly boost your speed.
If the screen starts flickering or even losing the base at 10 or even 15 mph, your own transducer is likely catching air or is usually mounted way too high. In the event that you see the big spray of water coming up over the back of the record, it's probably as well low. A few small adjustments on the dock can make the world of distinction. It's rarely perfect on the very first try, so don't get discouraged when you have to tweak the position or the height the couple of periods.
Side image resolution considerations
In case you spent the extra money on a side-imaging unit, where to mount transducer on pontoon boats becomes a lot more critical. Side-imaging requires a "clear line associated with sight" to each the left and right. In the event that you mount this too close to the motor, the particular engine's lower device will literally prevent the view to one side.
In this particular case, you may have to trim the motor up slightly when you're scanning for fish, or mount the transducer on a bracket that will drops it straight down a bit lesser so it may "see" under the particular motor. Some men even run two transducers—one on every log—and work with a Y-cable to join them, though that's getting into pretty advanced territory for a casual weekend easy riding bike.
Final thoughts on the procedure
At the finish of the time, finding where to mount transducer on pontoon logs is about balance. A person want it deep enough to work, high enough to be safe, and a spot where the water is smooth. Take your time, look at exactly how the water moves behind your ship while someone else is generating, and you'll discover that perfect spot. Once it's called in, you'll stop worrying about the hardware and start actually finding the fish, which is the particular whole point in any case.
