Explanation towards required choices to complete the JT70 Jet Thruster system
Choose at which voltage you want to run the Jet Thruster pump unit.
Most boats have a 12V circuit. This doesn't mean you must have a 12V Jet Thruster motor.
With a 24, or 48v dedicated battery pack, it's possible to have a battery bank in a higher voltage and have it charged by your 12, or 24v alternator. We have created an Informative Website page towards this subject in which we fully explain how to create a different circuit
Go directly to the page with this link:
A: 24V Pump Motor (Standard) 1-2 minutes continuous run-time
Note 1: In case of a 12V circuit: Order a Master Volt Mac Plus step up charger (Not required in case of a 24V circuit)
Note 2: Order 2x Optima Yellow Top batteries to create a dedicated 24V battery bank
B: 48V Pump Motor (Popular choice for charter boats) 3-4 minutes continuous run-time and 10% more thrust power.
Note 1: In case of a 12V or 24V circuit: Order a Mastervolt Mac Plus step up charger
Note 2: Order 4x Optima Yellow Top batteries to create a dedicated 48V battery bank
Nozzles:
Corrosion resistant Composite nozzles
C - L
Nozzles are a crucial part in any Jet Thruster installation:
The water flow is directed to nozzles which are located Forward and Aft in the boat, just below the water line. Because each hull is different, and interiors may vary, we have created a series of nozzles with different flange angles in order to have the optimum nozzle for your boat. We have created a Informative Website page towards this subject in which we full explain how to select the correct Nozzle type:

M: Batteries
Optima batteries are the best choice for powering Jet Thruster systems. These batteries are Small, powerful and have excellent deep cycle capabilities. We recommend Optima only for Jet Thruster systems
(Set of 4) to create a dedicated a 24V OR 48V bank
O: Mastervolt Mac Plus Step up Charger 12-to-24V
The Mastervolt Mac Plus Step-Up Charger is a smart and efficient device designed to convert 12V energy from your service battery bank into 24V power for a dedicated battery bank. It activates only when your service batteries are being charged—whether by your engine or when connected to shore power—and runs an intelligent charging program to keep the Jet Thruster battery bank in optimal condition. This ensures long-term health and reliable performance for your system.
The compact design simplifies installation, reducing the need for extensive battery cabling, and integrates easily into your boat’s electrical system. It’s an excellent choice for maintaining the efficiency of your Jet Thruster.
For compatibility:
JT70 24V: | Mac Plus 12/24 |
JT70 48V: | Mac Plus 12/48 |
For boats with a 24V power circuit, options include Mac Plus 24/24 or Mac Plus 24/48.
P: Composite 2" Ball Valves instead of standard Stainless steel 2" ball valves
The use of Composite products is rapidly increasing in the marine industry. The reason is obvious. Composites work very well in Salt water environments, and valves will not deteriorate due to the corrosive nature of sea water. In case your boat is on salt water, we recommend composite valves over Stainless steel valves. We endorse the use of Composites based upon the unique and reliable characteristics and the positive feedback from the market.
Q: Zinc Anode for Pump Outlet
There are Stainless steel parts in and to the pump which benefit from a cathodic protection by use of Zinc in case of use in salt water. In order to protect the pump shaft, stainless steel impeller, pump outlet and pump inlet, we have developed an Anode kit to protect these parts.
(WS-CP-002-00) Pump outlet Anode.
The Anode holder and stainless steel outlet are directly connected the pump outlet shroud. The Anode kit provides pre-assembled cable set to connect the Stainless Steel parts to the anode holder
R: Wet Wipes
All threaded parts are connected with a Poly-Urethane sealant. Parts straight BSP threads (no NPT) and after all threads have been de-greased and thoroughly cleaned, all threads are covered with a rich amount of the adhesive. Both Male and Female threads must be fully covered. Inevitably, the sticky and very difficult to remove Poly-urethane sealant will get on your hands, tools and parts. Directly after you connected the parts, these wipes will allow you to wipe off the sealant from any surface. Try this with paper or cloth and you'll end up with a big mess. Use the wipe and deliver a spotless and professional installation. Highly recommended to have this bucket with 150 little towels around.
S: PU-Sealant
The only good way to connect install the BSP threaded parts, and nozzle and water inlet flanges is with use of a Poly-Urethane sealant. We recommend the Wurth Marine sealant.
T: Remove all Hose
- Tick the V box if you choose to buy the hose local. We will exclude the hose from the Installation kit
U: Hose (Plus length)
The installation kit provides 15M/33ft of Marine water hose in the right quality. In case 15M/33ft in not long enough you can order additional hose in the Installation kit
- Tick the W box and reduce the hose length from a standard 10m/33ft into 5m/16ft. In this case we will ship a total of 5M/16ft
