with a special mounting bracket which secures the LF3000 to the cylinder of the
existing outboard drive unit.
The 8,5 m (28') cable is terminated in the LFI3000 Mk2 Linear Feedback Interface
according to the wiring diagram.
Centre the drives. Loosely secure the LF3000 to the supplied mounting bracket, across

the endplate of the LF3000 hitting the end of the cylinder. Check that the outboard
motor can be tilted freely. Tighten all nuts and the mounting bracket.
