Since it’s inception, Dive Xtras has taken great strides to provide in-depth tech support for all our products. That same ideology is still present today with our new Piranha DPV. We now have highly detailed exploded view schematics available for the Piranha, including diagrams and factory part numbers for easy reference or replacement.
In the diving world, the Piranha DPV stands alone. As the only scooter on the market today with a fully modular design, the Piranha is leading the industry with a lighter, more compact, higher performing, and more efficient design than the industry standard.
This modular design enables the diver to stack batteries for longer burn time and accessories for use in exploration, surveying, collecting, or just plain fun diving! Every individual module of the Piranha DPV is neutrally buoyant. The Piranha comes weighted from the factory with easy user removable saltwater plates. These saltwater trim plates can be found on the underside of the nose and battery sections of the scooter. For freshwater diving, simply remove the steel saltwater plates from the nose and battery sections and replace the thumb screws. When you receive your new Piranha, connect the batteries, and your choice of accessories, and you are ready to go diving!
Whatever your diving endeavors; be it through tight shipwrecks, treacherous caves, or entrancing reefs, the Piranha will take you there!
We developed the Piranha with the diver in mind so that, ultimately, you can customize your own scooter. This extends to the handle and trigger. With the ability to adjust the trigger distance from the handle and swap right to left-handed dominant control, any diver can wield the Piranha comfortably, especially with the new ergonomic grip!
The Piranha handle was designed to be completely user adjustable with only 2 tools, a 2.5mm and a 4mm Hex (Allen) key. You can adjust the angle of the grip and the positioning of the trigger, all without losing the integrated GoPro mount!
From the factory, the handle on your Piranha comes in the orientation seen below in (fig.A).
Should you desire to change the spacing of the trigger from the grip, simply use a 2.5mm Hex (Allen) key to loosen and remove the screw that mounts the trigger to the trigger-rod. You will then rotate the trigger 180 degrees and reinstall the screw (fig.B).
Your Piranha comes with the handle and grip in a right hand dominate orientation. Changing the orientation of both these parts can be achieved using a 4mm Hex (Allen) key.
To change the angle of the grip, simply loosen the screw in the top of the handle (fig.D) and rotate the grip to the orientation you desire.
To change the orientation of the grip from right to left hand dominant you will need to loosen the screw in the grip so that you are able to pull the grip off of the trigger bar (fig.E).
Then remove the screw under the loop in the handle base (fig.F).
Once the screw is removed, pull the trigger bar out of the loop and re-insert it through the other side (fig.G).
Reinstall the screw under the loop of the trigger, then mount the left hand grip, found in your spares kit (fig.H).

Using the 3mm Hex (Allen) key, remove the three screws that hold the motor plate to the tail and set aside.
Using the 3mm Hex (Allen) Key, remove the center screw on the motor plate to release the propeller shaft and get rid of screw.
Lift the motor plate, with motor and electronics, out of the tail section.
Remove Pulley Drive belt and discard.
Using the 5/64” Hex (Allen) Key, remove the 2 thread locking set screws that secure the gear to the prop shaft and discard.
Lift the gear off the prop shaft and set aside.
Turn the tail section over so the propeller is facing up.
Lift propeller shaft out of the tail section.
On the propeller shaft, remove the spring and components from the prop shaft.
Using your finger, carefully pry the white ceramic shaft seal out of the tail.
Wipe the area that holds the shaft seal in place with a paper towel.
On the new shaft seal, apply silicone grease to the o-ring on the shaft seal.
On the shaft seal there is a ridge on one of the faces. Place the ridge down, smooth side up, and press in with your thumbs.
On the prop shaft, install the Shaft Seal spring and graphite ring. Use the included lubricant, or 3-In-One Oil, to make the installation of the spring and graphite ring easier. Do not get any lubricant on the face of the graphite ring.
Lubricate the prop shaft with the same oil that you used on the shaft seal spring and install the prop shaft into the tail.
Turn the tail section, with the prop shaft installed over
On the gear that you’ve removed, install the set screws, using the 5/64” Hex (Allen) Key, so they are just protruding the inside of the gear.
Slide the gear onto the prop shaft, making sure to line the set screws up with the grooves.
Use the 5/64” Hex (Allen) Key to screw the set screws in until they do not move.
Now re-install the motor plate with Heat Sink.
Place the new Pulley Drive Belt around the gear and hold in place while you place the motor mounting plate in the tail and secure the belt around the gear on the motor.
Using the 3mm Hex (Allen) Key, screw the M4x10 Thread Locking screw into the prop shaft. You should notice prop shaft being drawn up tight to the motor plate.
Using the 3mm Hex (Allen) Key, install the three screws that hold the motor plate to the tail.
Once done, ensure the belt is aligned properly on both gears. This takes a bit of work and you will need both hands inside the tail section to ensure alignment.
Install the vacuum tester on the tail section and place the nose on top of the tester.
Draw vacuum to around 15 inHg/50 kPa. Note the gauge reading and wait 15 min.
After 15 min, check the gauge. If the gauge did not move, you are ready to go diving. If the gauge did move, you will need to trouble shoot to see where the leak is.
