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) 2-3 minutes continuous run-time
Note 1: In case of a 12V circuit: Order Series Parallel Switch or 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 circuit: Order a Series Parallel and a Mastervolt Mac Plus step up charger
Note 2: In case of a 24V circuit: Order a Series Parallel Switch
Note 3: Order 4x Optima Yellow Top batteries to create a dedicated 48V battery bank
Pump head position:
The Jet Thruster pump head can rotate. This enables you to select the orientation which is best for the installation. The pump head position can be ordered in position you would like it to be in. If later on you prefer to change, this is no problem. All Jet Thruster pump heads can be changed. Read out manual how to change the postion.
C: Position #1(outlet shroud pointing up)
D: Position #2(outlet shroud pointing side-way)
Nozzles:
E - N
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:
Select a nozzle type with help of the tools we created: Go directly the to the Nozzle page with this link:
O: 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
P: Series Parallel Switch
In order to charge the dedicated 24V jet Thruster battery bank, the series parallel is a reliable automatic mechanical switch. It is a standard item on the Jet Thruster JT50 part list.
However: If you already have a 24V circuit to charge the dedicated 24V Jet Thruster battery bank, you do not need to order this switch. Deselect the switch by ticking the Minus-box, to exclude it from the package price
Q: Mastervolt Mac Plus Step up Charger 12-to-24V
The Mastervolt 12-to-24V Step up Charger is a Intelligent charger which converts 12V energy from your Service Battery bank into 24V to charge the dedicated battery bank. It does this only when your Service batteries are being charged if you run your engine, your service batteries are being charged, or in case your boat is connected with the land power. The Mastervolt Mac Plus will run an intelligent program to keep the dedicated Jet Thruster battery bank in optimum condition. The installation of this charger is very easy. It will enable a setup for the dedicated battery bank with minimum amount of battery cable. We endorse the use of this charger.
- You can deselect the Series-parallel switch and Select this product to upgrade your installation.
- In case of a 48V Battery bank in a 12V circuit: Select the Series Parallel Switch AND the Mastervolt Mac Plus
R: 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.
S: Zinc Anode for Pump Inlet or 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.
Depending on the available space for the pump, you can make a choice from the following two options.
Option 1: (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
Option 2:
(WS-CP-050-00) Pump inlet Anode. This is our Standard and most used option
The Zinc Anode kit includes a composite holder in which a zinc anode is present. With the provided cable set, all SS316 metal parts of the pump unit are connected with the zinc anode. Without the need of lifting the boat from the water, the zinc anode ring can be removed and replaced in case this is required over time.
T: 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.
U: 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.
V: Remove all Hose
- Tick the V-box if you choose to buy the hose local. We will exclude the hose from the Installation kit
W: 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
