Manual Scope:
Designed as a comprehensive workshop manual, intended for detailed repair and servicing.
Engine Type:
2-Stroke, Reciprocating Piston Internal Combustion
Displacement 3 Cylinder:
Typically in the range of 35 to 70 cubic inches (e.g., 35hp, 45hp, 55hp models).
Displacement 4 Cylinder:
Typically in the range of 70 to 100 cubic inches (e.g., 60hp, 75hp, 90hp models).
Horsepower Range:
Varied by specific model, commonly from 35 HP to 90 HP.
Torque Characteristics:
Designed for low-end torque suitable for boat propulsion.
Fuel Delivery:
Carbureted, with either a single carburetor per cylinder or a shared carburetor depending on model and displacement.
Fuel Type:
Unleaded gasoline mixed with 2-stroke engine oil.
Oil Mix Ratio:
Typically 50:1 or 100:1, depending on the specific engine model and oil type used (refer to manual for exact specification).
Induction Type:
Reed valve induction system.
Cooling Method:
Water-cooled, utilizing raw water drawn through the lower unit.
Drive System:
Outboard lower unit with integrated forward, neutral, and reverse gears (often referred to as a 'gearcase').
Shift Type:
Manual shift via a remote throttle/shift control or tiller handle.
Gear Ratios:
Specific gear ratios vary by model and are detailed within the manual.
Lubrication:
Lower unit gear oil, specification and capacity provided in the manual.
Hourly Checks:
Visual inspection of fuel lines, water intake, and general condition.
Annual Service:
Spark plug replacement, fuel filter change, gearcase oil change, water pump impeller inspection/replacement, carburetor cleaning/adjustment, internal engine lubrication.
Gear Oil Type:
Refer to manual for specific SAE viscosity grade (e.g., SAE 90) and API classification for marine lower unit gear oil.
2 Stroke Oil:
NMMA TC-W, TC-WII, or TC-W3 certified outboard 2-stroke oil (refer to manual for exact type recommended for 1969).
Common Problems:
Overheating due to clogged cooling passages or failed water pump impeller; carburetor gumming from old fuel; hard starting due to ignition issues; lower unit gear wear.
Maintenance Prevention:
Regular flushing with fresh water after use, proper fuel storage with stabilizer, timely replacement of wear items (impeller, spark plugs).
