Selection Guide

The tables below give indications of typical Model rating limits along with sizes and approximate power ranges. These are intended as guidelines only. There are many factors that determine the correct Q-SPD solution, such as vessel weight and style, power speed and mission. Q-SPD will complete a full analysis for all applications to determine the correct arrangement and drive option.  A number of new drive models are planned to become available during 2013.

Custom Solutions for Special Applications 

For special applications where a standard drive configuration above does not quite fit, Q-SPD are able to customise a solution to suit.  This might be for peed high speed applications or for very high stress or high usage applications such as military pursuit, or for low speed work boats that need even higher torque and thrust to carry heavy loads. Talk to Q-SPD about your needs and we will be able to help with the ultimate solution. 

Specifications are correct as at 1 February 2013 and are subject to change.
