Flushing with the Flushing Attachment

cC

Avoid running the outboard at high speed while on the flushing attachment, or overheating could occur.

1)Remove the top cowling and silencer cover. Remove the propeller.

2)Install a flushing attachment to the lower unit. (A flushing attachment is available from a Yamaha dealer).

3)Run the engine at a fast idle for 10~15 minutes supplying water.

4)Just prior to turning off the engine, quickly spray “Yamaha Stor-Rite Engine Fogging Oil” (Part No. LUB- STRRT-12-00) alternately into each intake manifold. When properly done, the engine will smoke excessively and almost stall.
