Page 19: Feature And Benefit
Special service tool / Feature and benefit Feature and benefit Water separator For the 2007 models, a fuel filter assembly with a water detection switch has been adopted on the fuel line as a system to improve engine protection. The water detection warnings are given only if the fuel filter assembly with a water detection switch is connected to the 6Y8 Multifunction Meter.
Page 20: Injector
INFO General information Injector The injector for the 2007 models was improved in order to reduce the amount of soot after combus- tion compared to the injector used for the 2006 model F(L)250A. Due to the change in the injector spray angle, the ECM fuel injection mapping was also changed. Therefore, be sure to use the 2007 model injector together with the 2007 model ECMs.
Page 21: Ecm
Feature and benefit The ECM changes due to the yearly modifications are listed in the following table according to the model for the F(L)200C, F(L)225B, F(L)250A. Due to the change in the injector spray angle, the ECM fuel injection mapping was also changed. È...

Page 28: Checking The Outboard Motor Mounting Height
INFO General information Checking the outboard motor mounting height 1. Check that the anti-cavitation plate is aligned with the bottom of the boat. If the mounting height is too high, cavitation will occur and propulsion will be reduced. Also, the engine speed will increase abnormally and cause the engine to overheat.
