1965 Chrysler 9.2 HP Outboard Specs & Part Numbers
Introduction to the 1965 Chrysler 9.2 HP Outboard
The year 1965 marked a monumental transition in the marine industry. It was the year Chrysler Corporation entered the outboard motor market by purchasing the West Bend Outboard Motor Division. The 1965 Chrysler 9.2 HP is a direct product of this acquisition, carrying forward West Bend’s proven engineering with Chrysler’s branding and refinement. Today, this vintage two-stroke engine is highly prized by collectors and classic boat enthusiasts for its lightweight design, reliable performance, and mechanical simplicity.
This technical guide provides comprehensive specifications, maintenance parameters, and historical context to help owners maintain, restore, and operate this classic outboard motor.

Overview & Technical Specifications
The Chrysler 9.2 HP is a twin-cylinder, loop-scavenged two-stroke motor designed for utility boats, small skiffs, and as a trolling motor for larger vessels. Below are the core technical specifications for this model:
| Specification | Value / Detail |
|---|---|
| Horsepower | 9.2 HP @ 4,750 RPM |
| Cylinder Configuration | 2-Cylinder (In-line) |
| Engine Type | Two-Stroke (Piston-Ported) |
| Displacement | 11.97 Cubic Inches (approx. 196 cc) |
| Bore and Stroke | 2.00 inches x 1.906 inches |
| Recommended Fuel-to-Oil Ratio | 50:1 (using TC-W3 rated outboard oil and unleaded gasoline) |
| Fuel System | Single-line fuel system with vacuum-operated diaphragm fuel pump |
| Weight | Approx. 56 lbs (25.4 kg) |
| Cooling System | Water-cooled (Shear-pin driven impeller) |
Note on Fuel Ratio: While early West Bend manuals occasionally recommended richer mixes (such as 24:1 or 30:1) with older non-detergent automotive oils, the introduction of modern TC-W3 standard outboard oils allows these engines to run safely and much cleaner at a 50:1 ratio.

Common Maintenance & Tune-up Specs
Keeping a vintage 1965 Chrysler outboard running smoothly requires attention to the ignition system, fuel delivery, and cooling. Below are the critical tune-up specifications needed for routine maintenance:
Ignition System
- Spark Plug Type: Champion L82C or L86C (Original spec: Champion L4J or UL81J)
- Spark Plug Gap: 0.030 inches (0.76 mm)
- Ignition Type: Flywheel Magneto with dual points and condensers
- Point Gap Setting: 0.020 inches (0.51 mm) at high point of cam lobe
- Timing: Pre-set via the throttle synchronization linkage; check points alignment if timing feels off
Carburetor Settings
The Tillotson or Carter carburetor used on this model is highly reliable but sensitive to debris. If you have rebuilt the carburetor, use these baseline settings to start the motor:
- Initial Idle Mixture (Low Speed) Needle: Open 1 to 1-1/4 turns from gently seated.
- High-Speed Jet: Most models featured a fixed high-speed jet, but if equipped with an adjustable high-speed needle, start at 1 turn open from gently seated.
- Idle RPM: Adjust the idle stop screw until the motor idles smoothly at roughly 700-800 RPM in forward gear.
Cooling & Lower Unit
- Impeller Maintenance: The water pump impeller is located in the lower unit housing above the gearcase. It is driven by a flat spot on the driveshaft. Inspect annually and replace if the rubber vanes show signs of cracking or taking a permanent “set.”
- Gearcase Lubricant: Use high-quality Marine SAE 90 Outboard Gear Lubricant (Hi-Vis or equivalent). Do not use modern synthetic automotive gear lubes unless they are specifically rated for marine use (to handle water emulsification).
- Gearcase Capacity: Fill from the bottom drain hole until fluid flows out of the top vent hole (approx. 5.5 to 6 oz).

Notable Features & Historical Context
The Chrysler-West Bend Legacy
In the early 1960s, Chrysler sought to compete with OMC (Johnson/Evinrude) and Mercury by offering a complete marine package: Chrysler boats, Chrysler inboard engines, and a new line of outboards. By acquiring West Bend’s outboard division in Hartford, Wisconsin, Chrysler instantly gained a catalog of reliable engine designs. The 1965 9.2 HP model represents this transitional year, featuring the robust, proven mechanical underpinnings of the West Bend “Golden Shark” series dressed in Chrysler’s new white and red styling cues.
Key Design Features
- Low-Profile Design: Unlike its bulky competitors of the era, the Chrysler 9.2 HP featured a remarkably slim, low-profile cowl design. This lowered the center of gravity on the transom and made portage much easier.
- Twist-Grip Throttle: Standardized on this model, the steering handle incorporated a twist-grip throttle mechanism, allowing one-handed operation of both steering and engine speed.
- Spline-Drive Propeller: While many smaller outboards of the 1960s still relied entirely on shear pins to protect the drivetrain, Chrysler’s lower unit integrated a resilient rubber-hubbed propeller alongside a traditional shear pin system for double protection against underwater impacts.
- Alumilite Pistons: The engine utilized lightweight aluminum alloy pistons designed to reduce internal reciprocating mass, which contributed to its quick throttle response and smooth idle qualities.
Pro-Tips for Restoration and Operation
If you are restoring a 1965 Chrysler 9.2 HP, pay close attention to the coils under the flywheel. The original vintage coils were insulated with a plastic coating that becomes brittle and cracks over decades, allowing moisture in and causing spark failure. Modern replacement coils are readily available online and will greatly improve starting reliability.
