There are three versions of motors utilized on Sleipner (Side-Power) Thrusters; the different motor versions are referred to as “K”, “S” or “R” versions.
Knowing your motor version is necessary in order to source the correct replacement Thermo-Switch, Brushes, and Brush Springs.
All other parts are interchangeable among the motor versions.
“K” version motors have a ventilated top cap on the motor that encloses the brush assembly. The cap is held in place by either two or four bolts.
“K” version motors have a total of eight brushes and springs; four sets of two brushes, each brush holder has two brushes and two brush springs.
