When operating in freezing temperatures, keep the lower unit submerged in the water at all times to avoid freezing and possible damage to the water pump and powerhead. Be sure to completely drain water from cooling system when removing motor from boat.
SPARK PLUG RECOMMENDATION AND REPLACEMENT
Using the correct spark plug is most important for efficient operation. The recommended spark plug for your motor is imperative along with the proper spark plug gap.
REMOVING MOTOR FROM BOAT
Disconnect remote control, if used, and fuel lines from motor. Loosen the clamp screws and lift motor vertically from boat. Hold motor in upright position to allow water to drain out. Do not place motor in a position where the lower unit will be higher than the power head – any water remaining in the exhaust tube may run into the cylinders and cause serious damage.
EXTERNAL MOTOR COVER FINISH
The finish on your motor is most likely baked enamel designed for use in either fresh or salt water. The only care necessary when used in salt water is to wash the entire motor with fresh water, wipe dry. An occasional coating of automotive wax may be applied.
HOW TO GET PEAK PERFORMANCE
Clean Boat Hull
Marine growth, present in fresh water as well as salt water, will cut down on boat speed. For maximum performance occasionally check and clean boat hull.
Always use fresh gasoline and check/change your fuel filters as needed. Gasoline/Ethanol that has been in a tank for a long period of time can cause running/performance problems.
CHECK TO WATER DISCHARGE
Avoid operating in shallow waters. In emergencies proceed at slow speed until deeper water is reached. Operating engine with lower unit dragging on bottom will result in propeller wear, cause sand or silt to be forced in water pump and may cause damage to pump. Always make sure your motor is discharging water and that it is not clogged with debris.
