Even boats as little as 20 feet can utilize underwater electric thrusters so well. If you're a boater, a thruster is a tool you'll find very useful. So, here are some of the factors you should look at when planning to install a thruster:


Motor Voltage


When a thruster has higher voltage requirements, it'll use less current when operating, resulting in smaller cable requirements. It is possible to use a 24V thruster that may be powered by two or more batteries.


Hydraulic or Electric?


If your vessel is already using an hydraulic system, a hydraulic thruster is the right choice.


Internal Versus External


Electric, external thrusters that are water-cooled can operate for longer periods. These may need fewer batteries since their amperage demands are lower. Typically, it's easier to install external thrusters, although they're not great for high-speed boats.


Thruster Propellers


When it comes to need for thrust, biased propellers seem to do a better job than the Kaplan-styled ones. You can achieve more thrust with a dual prop, but when you have a smaller boat, a single-propeller thruster won't disappoint.

The Thrust Element


Thrust should be the most desired attribute of an underwater thruster as it determines the push your vessel receives while in operation. The weight and size of your boat should dictate the level of thrust required. Again, if you usually sail in adverse weather conditions or heaving winds, your underwater motor boat needs higher thrust capabilities. It's more preferable to have excess power than not enough!


Thrust control is also an issue that may interest some boaters. When more thrust is achieved based on how far you push the joystick, you're given finer control, but the system costs more. Basic on-off thrust control is easy to use and cheaper.


Remote Control


Most underwater thrusters have the option for remote control. However, this should be an extra feature but not the substitute of a hard-wired control system, such as joystick or touchpad. The issue with remote control is the probability of battery juices depletion when least expected or just misplacement of the device. 


Position of Installation


Measure the available space and choose underwater electric thrusters that will fit well. The size of the tunnels' top ought to be at least three quarters of its diameter below water.


The Price


Take into account the size and weight of your vessel and price to ascertain that you're making an economical purchase. The power of the thruster merits consideration also. Equally important, consider installation fees. A bit of price comparison and internet research can help you find the ideal underwater electric thrusters for your boat.



If you're looking for an electric or hydraulic thruster, some of the important factors that can help you buy the right one for your boat are discussed above.
