CRUISING IN OTHER CONDITIONS
CRUISING IN SALT WATER
After operating in salt water, wash out the cooling-water passages with fresh water to prevent them from becoming cloggedup with salt deposits. NOTE: Refer to cooling system flushing instructions in "TRANSPORTING AND STORING OUTBOARD MOTOR".
CRUISING IN TURBID WATER
It is strongly recommended that the optional chromium-plated water-pump kit be installed if the outboard is to be used in turbid (muddy) water conditions.

TRANSPORTING AND STORING OUTBOARD MOTOR w
Leaking fuel is a fire hazard. When transporting and storing the outboard motor, close the air vent screw and fuel cock to prevent fuel from leaking.
EMK20210*
TRAILERING OUTBOARD MOTOR
The motor should be trailered and stored in the normal running position. If there is insufficient road clearance in this position, then trailer the motor in the tilt position using a motor support device such as a transom saver bar. For further details, consult your Yamaha dealer.
001185
w
8 Never get under the lower unit while it is tilted, even if a motor support bar is used. Severe injury could occur if the outboard accidentally falls. 8 USE CARE when transporting fuel tank, whether in a boat or car. DO NOT fill fuel container to maximum capacity. Gasoline will expand considerably as it warms up and can build up pressure in the fuel container. This can cause fuel leakage and a potential fire hazard.
cC
Do not use the tilt support lever/knob when trailering the boat. The outboard motor could shake loose from the tilt support and fall. If the motor can not be trailered in the down position, use an additional support device to secure it in the up position. 4-3

Clamp handle mounting model When transporting or storing the outboard motor while removed from a boat, fold the tiller handle and lean the motor on the tiller handle to keep in a horizontal position.
cC
Keep the power unit higher than the propeller at all times. Otherwise, cooling water can run into the cylinder, which could result in damage. NOTE: Place a towel or the like under the outboard motor to protect it from damage.

STORING OUTBOARD MOTOR
When storing your Yamaha outboard for prolonged periods of time, (2 months or longer), several important procedures must be performed to prevent expensive damage. It is advisable to have your outboard serviced by an authorized Yamaha dealer prior to storage. However, the following procedures can be performed by you, the owner, with a minimum of tools.

cC
8 To prevent problems which can be caused by oil entering the cylinder from the sump, keep the engine in the attitude shown when transporting and storing it. [. . . ] don't forget to include any important information such as names, addresses, model, engine serial number, dates, and receipts. CHANGE OF ADDRESS The federal government requires each manufacturer of a motor vehicle to maintain a complete, up-to-date list of all first purchasers against the possibility of a safety-related defect and recall. This list is complied from the purchase registrations sent to Yamaha Motor Corporation, U. S. A. by the selling dealer at the time of your purchase. [. . . ]
