9. Slip shrink tubing over end and use heat 

gun to cover end and main cable. 

IMPORTANT! Be careful not to damage 

cover of Reflex cable.  

10. If assembling away from the boat, 

lay cable out straight. Install tack swivel 

terminal on drive unit. Install the threaded 

adapter. 

IMPORTANT! Slide the heat-shrink tubing 

onto the cable before slipping the cable 

into the thimble. 

Slip the cable into the 

thimble and check to make sure the unit 

is shorter than the (FH) full-hoist length 

by the amount shown in the chart. Clamp 

cable and use hacksaw to cut the cable 

leaving a tail of: 
Unit 1 - 90 mm (3.5") 
Unit 2 - 100 mm  (4") 

Tip: Leave a longer tail if you are not 

sure about measuerments. See following 

pages on determining length at boat.
