Page 23 4. Tilting the motor Tilt the motor to prevent the propeller and gear case from hitting bottom when the boat is beached or stopped in shallow water. Stop the engine and turn the fuel valve lever off. Close the fuel cap vent knob. To avoid damaging motor, never use it as a handle for lifting moving Page 25 High attitude operation At high altitude, the standard carburetor air-fuel mixture will be exces- sively rich. Performance will decrease, and fuel consumption will increase.
High altitude performance can be improved by installing a smaller diameter main fuel jet in the carburetor and readjusting the pilot screw. If you always operate the outboard motor at altitudes higher than 6, feet above sea level, have your authorized Honda Outboard Motor dealer perform these Page Stopping The Engine 7. NOTE: lt is a good idea to stop the engine with the emergency stop switch lanyard from time to time to be sure that the switch is operating properly.
Page 27 3. Turn the fuel valve lever OFF. Page Maintenance 8. Inspect or service as scheduled- below. Shut off the engine before performing any maintenance. If the engine must be run, make sure the area is well ventilated. Never run the engine in an enclosed or confined Page 29 1. Tool kit and spare parts The following tools and spare parts are supplied with the outboard motor for maintenance, adjustment, and emergency repairs. Page 30 2. Engine oil change Drain the oil while the engine is still warm to assure rapid and complete draining.
Turn the fuel valve lever OFF, and close the fuel cap vent knob. Remove the oil filler cap, and turn the motor on its side to drain the oil. Stand the engine in an upright position, and fill the crankcase with the recommended oil see page 9. Page 31 3. Remove the level plug and see if oil flows out. Page 32 5. Remove the spark plug cap. Use the wrench supplied in the tool kit to remove the spark plug. Visually inspect the spark plug. Discard the spark plug if there is apparent wear, or if the insulator is cracked or chipped.
Page 33 6. Cleaning and flushing After each use in salt water or dirty water, thoroughly clean and flush the outboard motor. Wash the outside of the outboard motor with clean, fresh water. Remove the propeller.
Stand the motor in a suitable container of water. The water level must be at least 2 inches above the anti-ventilation plate. Page 34 7. Page 35 8. Shear pin change A shear pin is used to protect the propeller and drive mechanism from damage when the propeller strikes an obstruction.
Remove the cotter pin and the propeller. Remove the broken shear pin and replace it with a new one. Page 36 9. Servicing a submerged motor A submerged motor must be serviced immediately after it is recovered from the water in order to minimize corrosion. If there is a Honda outboard motor dealership nearby, take the motor immediately to the dealer. If you are far from a dealership, proceed as follows: l. Drain the water from the extension case. Disengage the emergency stop switch clip from the engine stop switch to prevent starting, pull the starter rope several times to expel the water from the extension case.
If the outboard motor is put on its side immediately after Page 38 3. To carry, hold the motor by the carrying handle. Do not carry by the engine cover. Vertical transport or storage: Attach the stern bracket to a stand. Page Troubleshooting 1 O. Is the emergency stop switch clip in place? Is there fuel in the fuel tank? Is the fuel cap vent knob turned to open?
Is fuel reaching the carburetor? Loosen the carburetor drain screw to see if there is fuel in the carburetor float bowl. Page 1. Page Warranty Service If you have a warranty problem that has not been handled to your satisfaction, Page 42 Current customer service contact information: Your owner's manual was written to cover most of the questions you might ask about your Honda. Any questions not answered in the owner's manual can be answered by your Honda dealer.
If your dealer doesn't have an immediate answer, they should be able to get it for you. Page 43 MEMO If you suspect water in the gearcase, start by draining and closely inspecting the fluid refer to the procedures found in the Maintenance and Tune-Up section.
Then, refill the unit with fresh oil and test the outboard by using it! Watch the fluid level closely after the test, and for the first few outings. If any oil leaks out or water enters, either the propeller shaft seal must be replaced or the gear case must be disassembled, inspected and completely overhauled. To be honest, a complete overhaul is recommended, because corrosion and damage may have occurred if moisture was in the gearcase long enough.
But, in some cases, if the leak was caught in time, and there is no significant wear, damage or corrosion in the gearcase, the propeller shaft seal can usually be replaced with the gearcase still installed to the outboard.
The last, most important task you can perform to help keep your gearcase in top shape, is to flush the inside and outside of the gearcase after each use. Cleaning the gearcase will also help you spot potential.
A neglected lower unit cannot be expected to perform to maximum efficiency, compared with a unit receiving TLC tender loving care trouble, such as gearcase oil leaks, cracks or damage that may have occurred during use.
Remove any sand, silt or dirt that could potentially damage seals or clog passages. Once you've rinsed the outside, hook up a flushing device and do the same for the inside. Again, details are found in the Maintenance and Tune-up section, look under Flushing the Cooling System. The most common reason for removrng and installing the gearcase IS to perform service inspect or replace the water pump impeller. On all motors except the 2.
For safety, disconnect the spark plug lead, then ground it to the cylinder head. If necessary for service or access, remove the propeller, for details refer to the procedure in the Maintenance and Tune-Up section. Remove the two screws securing the lower unit to the exhaust housing. Taking Care not to damage the driveshaft and the water tube, separate the lower unit from the exhaust housing by pulling straight downward.
If necessary for service or overhaul, drain the gear oil from the gearcase. Thoroughly inspect the gearcase and exhaust housing for signs of damage. Make sure all mating surfaces are clean and free of debris, corrosion or damage.
