JetX-80V3 Propulsion Unit – Unique propulsion unit concept for Electric Surfboard

JetX-80V3 Propulsion Unit is a updated version of our most sold 80mm jet pump. The new jet pump version has more efficient impeller which  highly improves the thrust and water suction. It can produce 6,5 kg (64 Newtons) of static thrust per 1 kW of power (tested with 180kv outrunner brushless motor).

New, robust design with two separated open loop water cooling systems. The first one cools down the ceramic bearing and the shaft, and the second one is used to cool down electric/gasoline engine and electronics. If second stage is not needed it can be easily bypassed from brass outlet to inlet using a short tube. First stage is always in operational mode and takes care of the constant cooling of the bearing. With this innovative cooling technique there is no need for additional external tube in the nozzle. Both cooling circles have outlet directly in suction system which prevents pressure loss.

Improvements:
JetX-80V3 Propulsion Unit Impeller Shaft
Shaft Assembly

 

 

  • New impeller design provides better water suction in comparison with previous versions. The new shape of the impeller blades makes the impeller less prone to cavitation at higher rpm. Carbon Fiber impeller can withstand high loads while accelerating with vessel.

 

 

 

 

JetX-80V3 Propulsion Unit Nozzle
New Nozzle Design
  • New nozzle contains 8 pole stator, whose vanes were carefully developed and tested under various circumstances in dyno testing pool. Their new shape enable high efficiency and water flow, which is transformed from swirling to straight output jet with high velocity. Nozzle outlet also got bigger compared to previous version for larger water flow.

 

 

 

JetX-80V3 Propulsion Unit Stainless Steel Intake Guard
Stainless Steel Intake Guard

 

 

 

 

 

New intake guard is made from high strength marine grade stainless steel 316L, which is able to withstand salt water environment. With new JetX-80V3 Propulsion Unit, the intake guard is integrated in jet pump itself and it prevents suction of grass, rocks, dirt, fish etc…, into the jet system. Steel parts are cut with precise laser to ensure perfect fit. Carbon fiber part of intake guard directs the waterflow directly to the impeller. This improve water inlet and consequently the vessel’s grip on the water when moving.

Main Housing With Motor Mount Attachment Points

 

 

  • The turbine housing is designed in a way that allows an easy motor attachment. With such an attachment, we can easily align the engine and turbine shafts, which are connected to each other with a flexible coupling. Bottom part should be sealed with silicone glue and screwed with 6 mounting bolts.

 

 

 

Features:
  • 4 mm thick walls of main housing
  • 4 mounting brass inserts for motor mount
  • 6 mounting brass inserts on the bottom for easier pump installation
  • 5 brass inserts for nozzle attachment
  • 12 mm marine grade stainless steel 316L shaft (salt water A4 quality)
  • flexible coupling 10-12 mm
  • 2x high speed ceramic bearing
  • mechanical seal on the shaft
  • housing material: acrylonitrile styrene acrylate
  • impeller material: PET- carbon fibre
  • stainless steel bolts
  • stainless steel + carbon fiber intake guard
  • housing color: black
Package includes:
  • main housing
  • nozzle (no steering)
  • shaft with carbon fiber impeller
  • anti-slip felxible coupler 12mm
  • stainless steel + carbon fiber intake shield
  • gaskets
  • instruction manual

We advise using our 8kW sensored brushless motor. Please check our store to get more information about the motors.

Feel free to contact us with details and we can make you custom motor mount or some other modifications like impeller rotation side, etc…

 

Note: jet pump in video uses development nozzle and has different shape on the outside. You will get the same nozzle as shown in the photos.
