Fuel delivery problems have been around since the first internal combustion engine was introduced to mankind. Changing fuel formulations and the complexity of modern outboard motors, plus the amount of use (or, more correctly, the lack of use) by the typical consumer have increased the need to be very thorough when servicing a fuel system.
Frequently overlooked when servicing and troubleshooting fuel system issues are the multiple fuel filters and strainers located in many systems. It is imperative when troubleshooting an engine with fuel starvation issues to check and clean all filters, including the filters in the fuel injectors. Filters should be replaced during routine service as specified in the appropriate maintenance schedule chart located in the applicable Owner’s Manual.
