First a timely warning to all new or inexperienced inland boaters. Soon we will be suffering leaf fall and when we do, the leaves will pack themselves around the propeller. This causes a loss of speed, makes the engine struggle and may even make black smoke. When you stop to look down the weed hatch the leaves all float away so you see nothing. The trick is to put the boat into astern for a moment or two each time it starts to slow down. That will spin the leaves off the prop.
Now a different topic. Trying to understand what a reader means in a question can be tricky, especially if technical terms are misused, although I always do my best. If my answer does not seem to relate to your question, please come back and explain why. If you don’t come back or answer further questions I pose, then I have no way of knowing the problem has not been solved. It is harder to diagnose faults just from words, so photos always help – but not via the Canal Boat Forum. Please email the editor or send them direct to me, [email protected]ing.co.uk.
