Installation Overview

Before you start installation, we encourage you to read these instructions carefully in order to get the full benefit from your PiranhaMAX.

There are three basic installation tasks that you must perform for the PiranhaMAX:

•Installing the Control Head

•Installing the Transducer

•Testing the complete installation and locking the transducer position.

NOTE: In addition to the hardware supplied with your transducer, you will need a powered hand drill and various drill bits, various hand tools, including a ruler or straightedge, a level, a 12" plumb line (weighted string or monofilament line), marker or pencil, safety glasses and dust mask, and marine-grade silicone sealant.

NOTE: If you have purchased a PiranhaMAX Portable unit, proceed to PiranhaMAX Portable Case Assembly for installation instructions. If you are planning a fixed installation, proceed to Fixed Control Head Installation.

1	Installation Overview

Fixed Control Head Installation

1. Determine Where to Mount

Begin the installation by determining where to mount the control head. Consider the following to determine the best location:

Figure 1

Figure 2

•To check the location planned for the control head, test run the cables for the power and transducer. See Transom Transducer Installation in order to plan the location of the transducer and cable route.

•The mounting surface should be stable enough to protect the control head from excessive wave shock and vibration, and should provide visibility while in operation.

•Your PiranhaMAX uses a tilt and swivel mounting base. The mounting area should allow sufficient room for the unit to pivot and swivel freely, and for easy removal and installation (Figures 1 and 2).

2. Connect the Power Cable to the Boat

A 6' long power cable is included to supply power to the control head. You may shorten or lengthen the cable using 18 gauge multi-stranded copper wire.

CAUTION! Some boats have 24 or 36 Volt electric systems, but the control head MUST be connected to a 12 VDC power supply.

The control head power cable can be connected to the electrical system of the boat at two places: a fuse panel usually located near the console, or directly to the battery.

NOTE: Make sure that the power cable is not connectedto the controlhead at the beginning of this procedure.

2.With the control head in place, tilt and/or swivel the unit through its full range to make sure there is enough cable slack for the unit to move freely. Hand tighten the thumbknob bolt when you achieve the desired position for the control head.

You are now ready to install the transducer. Proceed to Transom Transducer Installation Overview.

7	Fixed Control Head Installation

Transom Transducer Installation Overview

Following are instructions for transom mount installation. The transom mount installation provides the least loss of signal since the transducer is mounted outside the hull. This installation also allows adjustment of both running angle and depth after the transducer is mounted, which enables you to tune the installation for best results.

NOTE: Due to the wide variety of hulls, only general instructions are presented in this installation guide. Each boat hull represents a unique set of requirements that should be evaluated prior to installation. It is important to read the instructions completely and understand the mounting guidelines before beginning installation.

NOTE: When drilling holes in fiberglass hulls, it is best to start with a smaller bit and use progressively larger drill bits to reduce the chance of chippingor flaking the outer coating.

NOTE: If you cannot find a transom mount location that will work for your boat hull, a different mounting technique or transducer type should be considered. See the FAQ (Frequently Asked Questions) section of our Web site at humminbird.com or call our Customer Resource Center at 1-800-633-1468 .

Transom Transducer Installation Overview

Transom Transducer Installation

1. Locate the Transducer Mounting Position

Turbulence: You must first determine the best location on the transom to install the transducer. It is very important to locate the transducer in an area that is relatively free of turbulent water.

Consider the following to find the best location with the least amount of turbulence:

Areas of Possible Turbulence

Rivets	Hull
Transom	Strakes

Figure 9

Stepped Hull

•As the boat moves through the water, turbulence is generated by the weight of the boat and the thrust of the propeller(s) - either clockwise or counter-clockwise. This turbulent water is normally confined to areas immediately aft of ribs, strakes or rows of rivets on the bottom of the boat, and in the immediate area of the propeller(s). Clockwise propellers create more turbulence on the port side. On outboard or inboard/outboard boats, it is best to locate the transducer at least 15" to the side of the propeller(s) (Figure 11).

Step

Rib

Figure 10

•The best way to locate turbulence-free water is to view the transom while the boat is moving. This method is recommended if maximum high-speed operation is a high priority. If this is not possible, select a location on the transom where the hull forward of this location is smooth, flat and free of protrusions or ribs (Figure 9).

•On boats with stepped hulls, it may be possible to mount the transducer on the step. Do not mount the transducer on the transom behind a step to avoid popping the

9	TransomTransducer Installation

transducer out of the water at higher speeds. The transducer must remain in the water for the control head to maintain the sonar signal (Figure 10).

•If the transom is behind the propeller(s), it may be impossible to find an area clear from turbulence, and a different mounting technique or transducer type should be considered, such as an Inside the Hull Transducer.

•If you plan to trailer your boat, do not mount the transducer too close to trailer bunks or rollers to avoid moving or damaging the transducer during loading and unloading of the boat.

•If high speed operation is critical, you may want to consider using an In-Hull transducer instead of this Transom Mount transducer.

Find a turbulence-free location at least 15” from the propeller(s) and not in line with trailer bunks or rollers. (Figure 11).

NOTE: The hydrodynamic shape of your transducer allows it to point straight down without deadrise adjustment (Figure 12).

NOTE: If you cannot find a transom mount location that will work for your high-speed application, please visit the FAQ (Frequently Asked Questions) section of our Web site at humminbird.com or call our Customer Resource Center at

1-800-633-1468.

2. Prepare the Mounting Location

After determining the mounting location for the transducer, follow the steps below to position and mount the transducer bracket.

1.Make sure that the boat is level on the trailer, both from port to starboard and from bow to stern, by placing your level on the deck of the boat, first in one direction, then in the other.

2.Hold the mounting bracket against the transom of the boat in the location you have selected (Figure 13). Align the bracket horizontally, using the level. Make sure that the lower screw hole protrusion does not protrude past the bottom of the hull, and there is at least 1/4" clearance between the bottom of the bracket and the bottom of the transom for fiberglass boats, and 1/8" clearance for aluminum boats (Figure 14).

NOTE: If you have a flat-bottomed aluminum boat, some additional adjustment may be needed to accommodate the rivets on the bottom of the boat (i.e. the gap may need to be a little smaller than 1/8"). This will help you to avoid excessive turbulence at high speeds.

NOTE: If your propeller moves clockwise as the boat moves forward (as you're facing the stern of the boat from behind), mount the transducer on the starboard side, and align the bottom right corner of the mounting bracket with the bottom of the boat. If your propeller moves counterclockwise as the boat moves forward (as you're facing the stern of the boat from behind), mount the transducer on the port side, and align the bottom left corner of the mounting bracket with the bottom of the boat.

3.Continue to hold the bracket on the transom of the boat, and use a pencil or marker to mark where to drill the two mounting holes. Mark the drill holes near the top of each slot, making sure that your mark is centered in the slot (Figure 15).

NOTE: The third hole should not be drilled until the angle and height of the transducer is finalized, which you will not do until a later procedure.

11	TransomTransducer Installation

4.Make sure that the drill bit is perpendicular to the actual surface of the transom, NOT parallel to the ground, before you drill. Using a 5/32” bit, drill the two holes only to a depth of approximately 1”.

NOTE: On fiberglass hulls, it is best to use progressively larger drill bits to reduce the chance of chipping or flaking the outer coating.

3. Assemble and Mount the Transducer

In this procedure, you will assemble the transducer using the hardware provided, then mount it and make adjustments to its position without locking it in place.

NOTE: You will initially assemble the transducer and the mounting bracket by matching the two ratchets to a numbered position on the transducer knuckle. Further adjustments may be necessary.

1a. If you already know your transom angle, refer to the chart below for the initial position to use to set the ratchets (Figure 16). If your transom is angled at 14 degrees (a common transom angle for many boats) use position 1 for the ratchets. In either case, go to step 2.

1b. If you do not know your transom angle, measure it using a plumb line (weighted nylon string or monofilament line) exactly 12 inches long. Hold the top of the plumb line against the top of the transom with your finger, and wait until the line hangs straight down (Figure 17). Using a ruler, measure the distance from the bottom of the plumb line to the back of the transom, then use the chart (Figure 16).

NOTE: It is important to take your measurement in the location shown in Figure 17, from exactly 12 inches down from the top of the transom.

If you are setting the ratchets at position 1, the beads on each ratchet will line up with the rib on the transducer knuckle to form one continuous line on the assembly (Figure 18b).

NOTE: The ratchets are keyed. Make sure that the square teeth on each ratchet face the square teeth on the transducer knuckle, and the triangular teeth face outward.

Hold the ratchets on the transducer knuckle with one hand and fit the mounting bracket over them until it snaps into place with the other hand. Refer to the illustration (Figure 18d).

4.Align the mounting bracket transducer assembly with the drilled holes in the transom. With a 5/16" socket driver, mount the assembly to the transom using the two #10 - 1" long screws provided (Figure 20).

Hand tighten only!

NOTE: Make sure that the mounting screws are snug, but do not fully tighten the mounting screws at this time to allow the transducer assembly to slide for adjustment purposes.

5.Adjust the initial angle of the transducer from back to front by rotating the transducer until the side seam on the transducer is almost parallel with the bottom of the boat, one click at a time in either direction (Figure 21 and 22).

NOTE: The transducer has a natural downward slant of 4-5 degrees from leading edge (closest to the boat transom) to trailing edge (farthest away from the boat). Looking at the back of the transducer, the seam should be slightly below the bottom of the hull.

7.Continue to adjust until the bracket is also level from port to starboard (horizontally level as you look at the transducer from behind the boat [Figure 24]).

8.Mark the correct position on the transom by tracing the silhouette of the transducer mounting bracket with a pencil or marker.

	9. Tighten the pivot bolt, using the pivot screw
	and nut to lock the assembly. Hand tighten
	only!

	10. Hand-tighten the two mounting screws.
	NOTE: You will drill the third mounting hole and finalize the
	installation after you route the cable and test and finish the
	installation in the following procedures.

4. Route the Cable

The transducer cable has a low profile connector, which must be routed to the point where the control head is mounted. There are several ways to route the transducer cable to the area where the control head is installed. The most common procedure routes the cable through the transom into the boat.

NOTE: Your boat may have a pre-existing wiring channel or conduit that you can use for the transducer cable.

1.Unplug the other end of the transducer cable from the control head. (The transducer cable was connected in the earlier section Attach the Cables to the Control Head). Make sure that the cable is long enough to accommodate the planned route by running the cable over the transom.

CAUTION! Do not cut or shorten the transducer cable, and try not to damage the cable insulation. Route the cable as far as possible from any VHF radio antenna cables or tachometer cables to reduce the possibility of interference. If the cable is too short, extension cables are available to extend the transducer cable up to a total of 50'. For assistance, contact the Customer Resource Center at humminbird.com or call 1-800-633-1468 for more information.

NOTE: Allow enough slack in the cable for slight movement at the pivot point. It is best to route the cable to the side of the transducer so the transducer will not damage the cable during movement.

2a. If you are routing the cable over the transom of the boat, secure the cable by attaching the cable clamp to the transom, drilling 9/64" diameter holes for the #8 x 5/8" wood screws, then skip directly to step 5 to connect the cable.

or...

2b. If you will be routing the cable through a hole in the transom, drill a 5/8" diameter hole above the waterline. Route the cable through this hole, then fill the hole with marine-grade silicone sealant and proceed to the next step immediately.

3.Place the escutcheon plate over the cable hole and use it as a guide to mark the two escutcheon plate mounting holes. Remove the plate, drill two 9/64" diameter x 5/8" deep holes, and then fill both holes with marinegrade silicone sealant. Place the escutcheon plate over the cable hole and attach with two #8 x 5/8" wood screws. Hand tighten only!

4.Route and secure the cable by attaching the cable clamp to the transom. Drill one 9/64" diameter x 5/8" deep hole, then fill hole with marine-grade silicone sealant, then attach the cable clamp using a #8 x 5/8" screw. Hand tighten only!

NOTE: If there is excess cable that needs to be gathered at one location (as shown in the illustration), dress the cable routed from both directions so that a single loop is left extending from the storage location. Doubling the cable up from this point, form the cable into a coil. Storing excess cable using this method can reduce electronic interference (Figure 26).

5.Plug the cable connector back into the control

head. The slots are keyed to prevent reversed installation, so be careful not to force the connector into the holder.

Your control head is now ready for operation.
