Can a Lewmar Thruster replace my existing installation/ I have a tunnel and standard fit by another manufacturer?
Yes in most cases providing the tunnel has the same internal diameter.
Can I install the Thruster myself?
The majority of the work involves choosing the location and installing the tunnel. A suitably qualified person should always carry out this work.
What Battery power do I need?
Thrusters have very powerful electric motors and it is recommended where possible to have a dedicated Battery close to the Thruster with a separate charger. This saves the problems of installing expensive, large cables from the main battery bank.
I am buying a new boat but haven’t decided to have a Thruster installed can it be fitted later?
Yes, there are plenty of installers around. It may cost a little extra and will involve hauling the boat and a few days of installation.
Why do I need a Thruster?
A Thruster makes boat handling, especially in tight harbours, much eaiser by gently moving the Bow with a small independently driven prop without having to use the main engine.
