Outboard Service Kit 6E0-W0078-A2 646-24251-02 66M-12411 for Yamaha 4HP F4A Water Pump Filter Thermostat

Product Overview

Outboard service kit, a direct replacement part for Yamaha 4 HP F4A four stroke outboards built from 1998 to 2008. One box covers the water pump repair kit 6E0-W0078-A2, the fuel filter 646-24251-02, the thermostat 66M-12411-01, a thermostat gasket, four drain gaskets and a cotter pin. The whole kit weighs 252 g in a 150 mm x 100 mm x 65 mm box (5.91 in x 3.94 in x 2.56 in).

This is the annual service in one box. Instead of ordering the pump kit, the filter and the thermostat separately, the three service items that most often get skipped on a small four stroke come together here.

The impeller in the kit has a 39.96 mm outer diameter, a 10.4 mm inner bore and a 12.55 mm height, with 6 blades on a key drive shaft and a neoprene body. Those are the dimensions to check against your old impeller if you are unsure of the model.

The thermostat is the part that gets overlooked. A sticking thermostat on these motors shows up as a motor that runs cold at low speed and then climbs quickly at the top end, and it is often blamed on the pump.
