This is one in a series of A Guide to Narrow Boat Problems.
Problem
Engine vibrates more than usual
Cause
Unbalanced prop, or loose engine mounting.
Solution
Moor up, switch off and access prop through the weed hatch. Remove anything wrapped around it. Replace hatch lid.
With large spanner turn to ensure each engine mounting nut is tight. If problem persists take it in for a service to get the prop and engine mounted in balance. Check condition of the prop at the same time.
Avoidance
Listen to your engine while underway. Differences in engine tone may be caused by narrow canals, deep cuts, water flow, sympathetic vibrations at certain speeds, or something more serious with the prop or the engine. Monitor continuously.
