Gale Model 3D19 Outboard Motor Specs & Overview

Overview of the Gale 3D19 Outboard Motor

Gale Products, a division of the Outboard Marine Corporation (OMC), produced some of the most reliable and accessible outboard motors of the mid-20th century. While OMC’s flagship brands—Johnson and Evinrude—dominated mainstream marine advertising, Gale manufactured high-quality, dependable motors sold both under their own name and through major department stores under house brand names like Sea King (Montgomery Ward) and Buccaneer. The Gale Model 3D19 is a quintessential late-1950s small outboard motor. Delivering 3.0 horsepower from a lightweight 38-pound single-cylinder powerhead, this model was designed for rowboats, small skiffs, and canoes, offering fisherman and recreational boaters easy portability and straightforward mechanics.

Two-Stroke Fuel & Oil Mixing Guide

Like most vintage 2-stroke outboard motors of its era, the Gale 3D19 requires oil pre-mixed directly into the gasoline. It relies on oil suspended in the fuel to lubricate its internal crankshaft bushings, connecting rod bearings, and cylinder walls.

• Fuel Ratio: A 24:1 fuel-to-oil mixture (5.3 oz of oil per gallon of gasoline, or approximately 1 pint of oil per 3 gallons of gas) is standard for OMC small singles from this era. Avoid modern thin 50:1 mixtures, as older bronze bushing powerheads require the extra cushion of a richer oil mix.
• Oil Type: Use a high-quality NMMA-certified TC-W3 2-stroke marine oil.
• Fuel Selection: Always use ethanol-free unleaded gasoline (87 octane or higher) when available. Modern ethanol blended fuels can deteriorate vintage rubber seals, gaskets, and fuel lines while absorbing moisture during storage.

Maintenance & Restoration Advice

Restoring a Gale 3D19 is an rewarding project due to the simplicity of its design and strong parts availability through crossover OMC components.

1. Ignition System Tune-Up

The built-in flywheel magneto utilizes a traditional points and condenser system. Over decades of sitting, the original OMC green ignition coils frequently crack due to age and moisture penetration. Inspect the coils under the flywheel; if cracked or leaking, replace them with modern OMC-style ignition coils. Polish the contact points with fine emery cloth or replace them, setting the point gap to .020 inches at peak cam lift.

2. Cooling System & Water Pump

This motor relies on a positive displacement water pump fitted with a synthetic rubber rotor (impeller). Never run the engine dry out of the water, even for a few seconds, as this will destroy the rubber rotor. If bringing a long-dormant motor back to life, drop the gearcase and replace the cooling pump rotor to ensure proper water flow and prevent engine overheating.

3. Carburetor Overhaul

The variable-venturi carburetor is mechanically simple but sensitive to varnish buildup. Disassemble the carburetor, clean all internal passages with carb cleaner, and blow them out with compressed air. Rebuild kits are widely available. When setting the high-speed and low-speed needle valves, start by turning them gently to a light seat, then back them out approximately 1-1/2 turns as a baseline setting before fine-tuning in a test tank.

4. Steering Bracket & Lower Unit

Because this engine lacks a mechanical reverse gear, maneuverability is accomplished via 360° full-reversing steering. Ensure the swivel bracket is thoroughly greased using marine-grade grease so the motor pivots smoothly. Drain the lower unit gear housing and refill it with fresh marine outboard gear lubricant to protect the gears and verify that water has not intruded past the propeller shaft seal.
