The Coleman Outboard Motor, models F9.8BM, F8BM, and F6BM, is a powerful, economic, and safe 4-stroke engine designed for marine propulsion. It is manufactured with advanced technology, ensuring reliable operation under various conditions.

Function Description:

The Coleman Outboard Motor is designed to provide propulsion for boats. It features a tiller handle for steering and throttle control, a gear shift lever for forward, neutral, and reverse operation, and an engine stop button for emergency shutdowns. The motor is equipped with a start-in-gear protection device that prevents starting unless the gear shift is in neutral. An emergency stop switch lanyard is also provided for safety, which, when pulled, stops the engine. The motor can be tilted up and down to protect the propeller and casing from obstructions in shallow water and to reduce corrosion during storage.

Usage Features:

Installation: The outboard motor should be mounted on the center line (keel line) of the boat. Proper mounting height is crucial for efficiency, with the anti-cavitation plate positioned between the bottom of the boat and 25mm below it. Clamp screws must be tightened securely, and bolting the engine to the boat through the transom is recommended for safety. An engine restraint cable or chain should be used if equipped.
Breaking-in: New engines require a break-in period to ensure proper wear of moving parts. This involves running the engine at specific RPMs for the first 10 hours of operation: 2000r/min (half throttle) for the first hour, 3000r/min (three-quarter throttle) for the second hour, and avoiding continuous full throttle for more than five minutes at a time for the next eight hours.
Pre-operation Checks: Before starting, ensure sufficient fuel, check for fuel leaks, confirm tight fuel line connections, and verify the fuel tank is secure. Controls (throttle, shift, steering) should operate smoothly. The engine oil level must be checked and maintained between the upper and lower marks on the dipstick. The engine should never be started out of water to prevent overheating.
Starting Engine: Connect fuel joints, loosen the air vent screw on the fuel tank cap, and squeeze the primer pump until firm. Place the gear shift lever in neutral. Attach the emergency stop switch lanyard. For cold starts, pull out the choke knob fully. Pull the manual starter handle slowly until resistance is felt, then give a strong pull to crank and start the engine.
Warming Up: After starting, warm up the engine for approximately 3 minutes at one-fifth throttle or less. Check for a steady flow of water from the cooling water pilot hole.
Shifting: Always close the throttle to idle or low speed before shifting. Move the gear shift lever quickly and firmly between neutral, forward, and reverse. When operating in reverse, go slowly and do not open the throttle more than half to maintain stability.
Tiller Control: The tiller handle is used to change direction (left or right). Speed is adjusted by turning the throttle grip counterclockwise to increase and clockwise to decrease. A throttle indicator on the grip shows fuel consumption relative to throttle position. A throttle friction adjuster allows setting resistance for constant speed operation.
Stopping Engine: Before stopping, allow the engine to cool at idle or low speed for a few minutes. Push and hold the engine stop button until the engine stops, or pull the emergency stop switch lanyard. Tighten the air vent screw on the fuel tank cap.
Trimming: The outboard motor trim angle can be adjusted using 4 or 5 holes in the clamp bracket. This helps optimize performance for different boat and operating conditions. Always stop the engine before adjusting the trim angle.
Tilting: The motor can be tilted up to protect the propeller in shallow water or for mooring. Ensure all people are clear and avoid pinching body parts. The motor cannot be tilted in reverse.

Maintenance Features:

Periodic Maintenance: Regular maintenance is crucial for performance and engine life. Most tasks should be performed by a qualified mechanic or authorized Coleman dealer, but some can be done by the owner.
Greasing: Various points on the motor require periodic greasing.
Spark Plug: Periodically remove and inspect the spark plug for wear and erosion. Replace if necessary with the correct type. Measure and adjust the electrode gap to 0.8-0.9mm.
Fuel System: Regularly check fuel lines for leaks, cracks, or malfunctions. Inspect the fuel filter periodically and replace if foreign matter is found. The fuel filter is a disposable spare part.
Idling Speed: Inspect idling speed using a diagnostic tachometer when the engine is fully warmed up. The specified idle speed is 950 ± 50Rpm.
Engine Oil: Change engine oil after the first 10 hours of operation, and then every 100 hours or at 6-month intervals. Change oil when warm. Ensure the outboard motor is upright, drain old oil completely, and refill with recommended SAE10W30 or SAE10W40 oil (0.8L).
Wiring and Connectors: Check that all grounding wires are secure and connectors are engaged.
Leakage: Check for exhaust, water, or oil leaks around the engine.
Propeller: Inspect propeller blades for wear, erosion, or damage. Check the propeller shaft, splines/shear pin, and oil seal for damage. Remove any tangled fishing line.
Gear Oil: Change gear oil after the first 10 hours, then every 100 hours or 6-month intervals. Tilt the motor, drain old oil, inspect for milky appearance (indicating water intrusion), and refill with Hypoid gear oil SAE # 90 (320 cm³).
Fuel Tank: Clean the fuel tank periodically by emptying, adding solvent, shaking, and draining. Clean the fuel filter and replace the gasket.
Anodes: Inspect external anodes periodically and remove scales. Consult a dealer for replacement. Do not paint anodes.
Top Cowling: Check the fitting of the top cowling and have it repaired if loose.
Maintenance Table: A comprehensive maintenance table provides guidelines for operations to be performed at 10 hours (1 month), 50 hours (3 months), 100 hours (6 months), and 200 hours (1 year).
Saltwater Use: After operating in salt, turbid, or muddy water, flush the engine with clean water after every use to prevent clogging and salt deposits.

Transporting and Storing:

Transporting: The motor should be transported upright (Figure 1). If laid down, place it as shown in Figure 2 or 3, using a towel or case protector (Figure 4) to prevent damage. Do not use the tilt support lever for trailering.
Storing: For prolonged storage (2 months or longer), store the motor upright. If storing on its side, drain engine oil completely and place it on a cushion. Ensure cooling water has drained. Store in a dry, well-ventilated place, away from direct sunlight.
Storage Preparation: Wash the motor with fresh water. Disconnect fuel and drain engine oil. Remove top cowling and silencer cover. Install on a test tank, ensuring fresh water level is above the anti-cavitation plate. Start the engine to flush the cooling system and perform fogging/lubrication with "Fogging Oil" or clean engine oil to prevent rust. Drain fuel from the tank, carburetor, and fuel lines.

Emergency Actions:

Impact Damage: If the motor hits an object, stop the engine immediately, inspect for damage, and return to harbor slowly. Have a Coleman dealer inspect it before further operation.
Starter Not Operating: In an emergency, the engine can be started with an emergency starter rope. Remove the top cowling, start-in-gear protection cable, and starter. Wind the rope around the flywheel rotor clockwise and pull strongly.
Submerged Motor: If submerged, immediately take it to a Coleman dealer. Thoroughly wash with fresh water, remove spark plugs to drain contaminants, drain fuel and engine oil, refill with fresh engine oil, and feed fogging oil through the carburetor and spark plug holes while starting. Do not attempt to run the motor until fully inspected.

Warranty:

Coleman Outboard Motors offers a 1-year limited warranty to the initial purchaser for manufacturing defects in material and workmanship. This warranty does not cover damage from improper maintenance, misuse, competition use, or unapproved modifications. An Emissions Control System Warranty is also provided, covering emission-related parts for 5 years or 175 hours, whichever comes first, provided proper maintenance is performed. Repairs under warranty should be performed by an authorized Coleman Outboard Retailer or comparable servicing dealer.
