8Flushing 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 the pro- peller.

2)Install a flushing attachment 1 to the cooling water inlet.

3)Run the engine at a fast idle for 10~15 minutes supplying fresh 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 the silencer cover. When properly done, the engine will smoke excessively and almost stall.

5)Remove the flushing attachment and wipe off any excess water.

6)Install the top cowling and the pro- peller.
