NOTICE : DANGER/WARNING/CAUTION/Note

Before installing, operating or otherwise handling your outboard motor, be sure to thoroughly read and understand this Owner's Manual and carefully follow all of the instructions. Of particular importance is information preceded by the words "DANGER," "WARNING," "CAUTION," and "Note." Always pay special attention to such information to ensure safe operation of the outboard motor at all times.

Failure to observe will result in severe personal injury or death, and possibly property damage.

Failure to observe could result in severe personal injury or death, or property damage.

Failure to observe could result in personal injury or property damage.

Note

This instruction provides special information to facilitate the use or maintenance of the outboard motor or to clarify important points.

EMERGENCY STOP SWITCH

The Emergency Stop Switch will stall the outboard motor when the stop switch tether is pulled off. This stop switch tether can be attached to the operator of the outboard motor to minimize or prevent injuries from the propeller in case the operator falls overboard. We highly recommend use of the Emergency Stop Switch tether.

Accidental activation of the Emergency Stop Switch (such as the tether being pulled out in heavy seas) could cause passengers to lose their balance and even fall overboard, or it could result in loss of power in heavy seas, strong currents, or high winds. Loss of control while mooring is another potential hazard. To minimize accidental activation of the Emergency Stop Switch, the 500 mm (20 inch.) stop switch tether is coiled and can extended to a full 1,300 mm (51 inch.).

SAFE OPERATION OF BOAT

!



As the operator/driver of the boat, you are responsible for the safety of those aboard and those in other boat around yours, and for following local boating regulations. You should be thoroughly knowledgeable on how to correctly operate the boat, outboard motor, and accessories. To learn about the correct operation and maintenance of the outboard motor, please read through this manual carefully. It is very difﬁcult for a person standing or ﬂoating in the water to take evasive action should he or she see a power boat heading in his /her direction, even at a slow speed. Therefore, when your boat is in the immediate vicinity of people in the water, the outboard motor should be shifted to neutral and shut off.

SERIOUS INJURY IS LIKELY IF A PERSON IN THE WATER MAKES CONTACT WITH A MOVING BOAT, GEAR HOUSING, PROPELLER, OR ANY SOLID DEVICE RIGIDLY ATTACHED TO A BOAT OR GEAR HOUSING.

SERVICING, REPLACEMENT PARTS & LUBRICANTS

We recommend t hat only an aut horized ser vice shop p erfor m service or maintenance on this outboard motor. Be sure to use genuine parts, genuine lubricants, or recommended lubricants.

MAINTENANCE

As the owner of this outboard motor, you should be acquainted with correct maintenance procedures. It is the operator's responsibility to perform all safety checks and to ensure that all lubrication and maintenance instructions are complied with for safe operation. Please comply with all instructions concerning lubrication and maintenance. You should take the engine to an authorized dealer or service shop for periodic inspection at the prescribed intervals. Correct periodic maintenance and proper care of this outboard motor will reduce the chance of problems and limit overall operating expenses.

MOUNTING

Outboard motor mounting must be performed by trained service person(s) using lift or hoist with sufﬁcient capacity.

INSTALLATION

1. Mounting the outboard motor on boat

Most boats are rated and certiﬁed in terms of their maximum allowable horsepower, as shown on the boat’s certiﬁcation plate. Do not equip your boat with an outboard motor that exceeds this limit. If in doubt, contact your dealer. Do not operate the outboard motor until it has been securely mounted on the boat in accordance with the instructions below.

Consult your authorized dealer to receive the proper instructions or ask your dealer to mount the motor as necessary.

Installation

Single-engine Installation

■

Position the outboard engine at the exact center of the stern, and mount it using a cushioning pad or plate.

Note

Twin-engine Installation

■

W h e n in s t al li ng two o u t b oa rd engines, be sure to keep an interval of 4 70~660mm (for 40,50,70 a nd 90 models) or 700~890mm (for 115 model) between the two.

Before beginning the running test,

●

check that the boat with maximum capacity loading ﬂoats on the water in a proper attitude. Check the position of water surface on the driveshaft housing. If the water surface is near the bottom cowling, in high waves, water may enter the engine cylinders.

Incorrect outboard motor mounting

●

height or existence of underwater object(s), such as hull bottom design, bottom surface conditions or underwater accessories, can cause water spray possibly reaching the engine through an opening of the bottom cowling during cruising. Exposing engine to such conditions for extended periods can lead to severe engine damage.

Transom Height

■

Install the engine with the Anti-ventilation Plate at a level 10~30mm(0.4~1.2in.) below the bottom of the boat.

Transom Matching

■

Be sure t hat an ti venti la tion p la te of the outboard is below the water surface when running with wide open throttle. In case the above condition cannot be met due to the shape of your boat, please consult your authorized dealer.

Overheating may occur if the Antiventilation Plate is at a level higher than the bottom of the boat, as a result of a lack of cooling water.

If the he igh t d iff ere nce exce eds 10~30mm (0.4~1.2 in) engine power performance is likely to be reduced as a result of increased water resistance to the gear case assembly.

Attaching the Clamp Bracket

■

After positioning the Clamp Bracket, ﬁx it with clamp screw then drill four holes in the transom board, matching the holes in the Clamp Bracket. Secure the engine with the supplied bolts (M12×105mm) and nuts, Be sure to use the washers. Use the larger diameter washers inside of the transom board and use the small diameter washers outside of the clamp bracket. The mounting holes may be drilled beforehand by re f e r r ing to t h e dimensional drawing.

Mounting the outboard motor without

●

following this manual can lead to unsafe conditions such as poor maneuverability, going out of control or ﬁre disaster.

Loose clamp screws and/or mounting

●

bolts can lead to the release or displacement of the outboard motor, possibly resulting in lost of control and/or serious personal injury. Be sure that fasteners are tightened to the speciﬁed torque (30 Nm (3.0kgf)13ft·lb). Check the fasteners for tightness from time to time.

Be sure to use outboard mounting

●

fasteners included in the outboard motor package or their equivalents in terms of size, material, quality and strength. Tighten fasteners to the speciﬁed torque (30 Nm (3.0kgf)13ft·lb). Test cruise to check if fasteners are tightened securely.

Outboard motor mounting must

●

be performed by trained service person(s) using lift or hoist with sufﬁcient capacity.

Propeller Selection

2.

A propeller must be selected so that the engine rpm measured at wide open throttle while cruising is within the max. operating range; 5,150 to 5,850 rpm For ge nuin e prope l lers , refe r to Propeller Table of this manual.

Notes

1. Apply sealing agent such as silicon sealer between bolts and transom board holes before tightening bolts.

2. Be sure to tighten mounting bolt nuts to speciﬁed torque.

The 115 model is supplied with no standard propeller. In other words, it is shipped from the factory without a propeller.
