Engine runs but prop doesn't turn

This is one in a series of A Guide to Narrow Boat Problems.

Problem
Engine runs but prop doesn't turn when gear lever engaged
Cause
Broken cable to gear box, or broken drive plate, or gear box.
Possibly failure of prop shaft coupling.
Solution
Switch off, moor up. Check oil level and top up if necessary. Try progressing at half power. If all fails call for help and probably suggest bringing a new cable (and hope it's only that ....)
Avoidance
In regular maintenance ensure gear lever cable runs freely. Lubricate as required.
