SUZUKI INJECTOR 15710-93J00

Function and technical context

This injector is part of the direct fuel injection system of high-power Suzuki outboard engines, responsible for spraying the fuel precisely into the combustion chamber to guarantee an optimal air-fuel mixture in each cycle. Its correct operation is decisive for the energy efficiency of the engine, the throttle response and the reduction of emissions. An injector in poor condition causes irregular combustion that results in loss of power, excessive fuel consumption and, in serious cases, damage to the pistons or the catalyst. The manufacturer reference 15710-93J00 identifies this part within the Suzuki DF200, DF225 and DF250 outboard range, and is also known by the OMC number 5035010.

When to replace this part?

The most common symptoms of a damaged injector include difficult cold starting, unstable or jerky idling, a sudden drop in speed when accelerating and a notable increase in fuel consumption; Sometimes the diagnostic scanner records specific injector fault codes per cylinder. It is recommended to check the condition of the injectors every 300-400 hours of operation or when any of the symptoms described appear, since in direct injection engines, nozzle wear directly affects the spray pattern. Replacing the injector preventively when detecting the first signs of failure prevents major breakdowns during navigation and protects the rest of the components of the injection system.
