1959 Gale 12 HP Buccaneer Outboard Specs & Part Numbers
1959 Gale 12 HP Buccaneer: Technical Guide & Spec Sheet
The 1959 Gale 12 HP Buccaneer is a classic representation of golden-era American marine engineering. Manufactured by Gale Products, a division of the Outboard Marine Corporation (OMC), these motors were prized for their rugged simplicity, reliability, and excellent power-to-weight ratio. They shared many internal components with their famous OMC siblings, Johnson and Evinrude, making them a favorite among vintage outboard collectors and restorers today.
Overview & Specifications
The Gale Buccaneer 12 HP was positioned as a versatile mid-range utility motor, perfect for fishing boats, runabouts, and light family pleasure crafts. Featuring a twin-cylinder powerhead, this model provided smooth power delivery compared to single-cylinder alternatives of the era.

Common Maintenance & Tune-up Specs
Performing routine maintenance on the Gale 12 HP is straightforward due to its open engine layout and the availability of interchangeable vintage OMC parts. Below are the critical tune-up settings required to keep this vintage outboard running smoothly.
Ignition & Electrical System
The 1959 Buccaneer uses the highly reliable OMC Universal Magneto system. If your motor has been sitting for a long period, the ignition coils may be cracked and will need replacement (common for vintage OMC outboards of this era).
- Spark Plugs: Champion J6C (Modern standard replacement)
- Spark Plug Gap: 0.030 inches (0.76 mm)
- Point Gap Setting: 0.020 inches (0.51 mm) at high point of the cam lobe
- Condenser Capacity: 0.18 to 0.22 microfarads
Carburetor Tuning (Initial Settings)
The carburetor features adjustable high-speed and low-speed needle jets. To perform an initial bench setting before starting a rebuilt motor:
- High-Speed Needle (Bottom): Gently turn clockwise until seated, then back out 1 full turn.
- Low-Speed Needle (Top): Gently turn clockwise until seated, then back out 1-1/2 turns.
- Fine-tune both needles while running the motor in a test tank under load at operating temperature.
Cooling & Gearcase
- Impeller: Located in the lower unit housing above the gearcase. Water pump impeller service is recommended every two seasons. Complete pump kits cross-reference with OMC part numbers of the same vintage.
- Gear Lube Type: Standard SAE 80W-90 Marine Gear Lubricant (Hi-Vis)
- Gearcase Capacity: Fill from the bottom drain hole until fluid flows out of the top level hole (approx. 9-10 oz).
Notable Features & History
The OMC Connection
While Evinrude and Johnson were positioned as OMC’s premium “flagship” lines, Gale Products served as the corporate division tasked with producing budget-friendly, high-utility options. Gale manufactured outboards under their proprietary “Buccaneer” brand, but they also private-labeled motors for major department stores and hardware chains, including Montgomery Ward (Sea King), Goodyear (Sea Bee), and Atlas (Royal).
Aesthetic Styling of 1959
By 1959, outboard manufacturers were embracing automotive-inspired design trends. The 1959 Buccaneer 12 HP features a striking, streamlined fiberglass shroud (cowling) accented with beautiful chrome script trim, deep-set controls, and a classic red, white, and blue/grey paint scheme. The top cowling hinges open for easy spark plug and carburetor access without requiring complete removal of the shroud.
The Two-Line Pressurized Fuel System
Unlike modern outboards that use a single-line vacuum fuel pump, the 1959 Buccaneer relies on a dual-line pressurized fuel system.
- One line pumps air pressure from the engine crankcase down into the fuel tank.
- This air pressure pushes the fuel up through the second line into the carburetor.
Safety Note: Ensure your vintage pressure fuel tank has intact, supple rubber gaskets. If the tank fails to hold pressure, the motor will starve for fuel. Many modern restorers convert these outboards to a single-line fuel pump system using a pulse vacuum line from the crankcase to allow the use of modern plastic fuel tanks.
Vibration Isolation Suspension
The 12 HP Buccaneer incorporates a “floating” powerhead design. The engine is suspended within its mounting brackets on heavy-duty rubber motor mounts. This isolation design drastically reduced tiller-handle vibration and boat hull resonance, a feature marketed by Gale as their “Super Quiet” operational system.
