5 TOP FIXES
FOR THE MOST COMMON PROBLEMS
1 RUNNING OUT OF FUEL
Carry a spare can. Top up the fuel, bleed the fuel line if needed. You may also need to change the filter.
2 FUEL CONTAMINATION
Diesel bug can easily block fuel lines and filters. Keep your fuel clean with additives, avoid running your fuel empty, and keep an eye on filters. A filter change may be sufficient to unblock the system, but a more serious case may mean there are several blockages to clear, in which case work through the fuel system methodically. Be aware that these problems can also be caused by air ingress in the fuel system.
3 LOW START BATTERY VOLTAGE
Few engines are fitted with hand start handles anymore, let alone fixed props or cylinder decompression levers. Make sure you can bridge your domestic and start batteries to get some more oomph if the start bank goes flat.
4 FOULED PROPELLER
The only way is to clear the prop. This will be difficult and potentially hazardous at sea. If you can still sail, get to a sheltered anchorage then sort it out in calm water. If your prop is anchoring you to an object on the seabed, it’s time to call for help.
5 RAW WATER BLOCKAGE
This is most likely indicated by an overheat alarm, and steam from the exhaust, if not smoke from the engine compartment. The water intake may have ingested seaweed, plastic or other debris. Start by checking and clearing the strainer, then check the impeller for damage. If the blockage is between the intake and the impeller, a dinghy pump attached to the hose can sometimes blow the blockage out with air pressure.
