Check Price on Amazon

Best for: jon boats in the 13–19 foot range needing steady, higher power without excessive weight. Why selected: This 4-stroke engine delivers up to 3.5 kW at 3600 rpm, hitting strong speed while maintaining manageable heat dissipation through multiple cooling holes. It includes air cooling to speed up cooling and reduce failure risk during extended runs. The CVT-like shifting provides smoother transitions, improving control in choppy conditions. Use this when you require reliable acceleration for larger lightweight hulls.

Caution: The specification highlights air cooling, but prolonged high-speed operation can still heat the housing; ensure adequate ventilation during runs and inspect heat dissipation paths regularly.

2-Stroke 3.5HP Outboard Motor — Gosangom

Best for: light, portable setups or emergency backup motors for inflatable boats and kayaks. Why selected: A compact 3.5hp, 2-stroke design with water cooling and a streamlined propeller provides strong thrust while keeping weight down. Its aluminum alloy build adds corrosion resistance for mixed freshwater and saltwater use. The motor travels easily to remote rivers and lakes. Use this when portability and quick deployment matter most.

Caution: Being a 2-stroke, it requires oil-muel and mixed-fuel handling; ensure proper fuel preparation and mixing to avoid engine damage.

CUKUSIN 4 Stroke 4HP Outboard Motor

Best for: beginners and casual boaters seeking ease of use and low maintenance. Why selected: Four-stroke operation reduces fuel mixing hassles, and a lightweight 15 kg design makes handling simple. The engine uses a lubricating system aimed at durability and smooth performance, complemented by a twist-grip throttle for safer maneuvering. Short past the basics: it’s versatile for inflatable, kayak, dinghy, canoe, and small boats. It’s a solid, all-around pick when reliability and ease are prioritized.

Caution: The short shaft design may not fit transoms with higher mounts; check transom height before purchase.

FXEIPOL 9HP Outboard Motor — 224cc

Best for: larger jon boats or inflatable boats requiring more power for faster travel and heavier loads. Why selected: A robust 9 hp output from a 224cc engine provides strong acceleration and reliable performance through air cooling and a CDI ignition system. Features like tilt and 360° rotation offer flexible steering, while the forward/reverse mechanism improves maneuverability in tight bays. Choose this if you need more power for bigger vessels or choppier waters.

Caution: Higher horsepower typically means greater weight and fuel use; ensure your transom and mounting hardware can support the load and that you have adequate fuel planning for longer trips.

4-Stroke 4HP Outboard Motor — YaggeBike

Best for: budget-conscious buyers needing a compact, easy-to-store motor. Why selected: A four-stroke, 4HP engine offers reliable performance with a water-cooled system for longevity and low maintenance. It emphasizes quick starts via CDI ignition and a lightweight build for simple handling, making it suitable for small jon boats and light duty tasks. Use this when cost and portability matter most.

Caution: The horsepower is modest, so use the unit within its comfort range for smaller boats and lighter loads to avoid underpowered conditions.

Buying Guide: Gas Motors For Jon Boats

Engine Type and Power

Four-stroke engines typically offer smoother idle, cleaner operation, and easier maintenance than two-stroke models. For larger jon boats, consider 6–9 hp equivalents; for small boats or light loads, 3–4 hp units may suffice. Match power to boat length, weight, and target speeds to avoid overloading transoms.

Shpts And Mounting Considerations

Short shafts are common for jon boats with low transoms, while longer shafts fit higher transoms or deeper-water operations. Check transom height and ensure the motor’s shaft length aligns well to avoid cavitation or submersion issues.

Cooling System

Air-cooled and water-cooled designs each have trade-offs. Air cooling is simpler and lighter but may heat faster in heavy use. Water cooling can support longer runs but adds complexity and potential maintenance points. For remote spots, plan for cooling needs based on typical trip durations.

Fuel Type and Efficiency

Two-stroke models deliver higher power-to-weight but require oil mixing and more maintenance. Four-stroke engines run cleaner and quieter and generally offer better fuel economy over longer trips. Consider availability of fuel and maintenance capacity in your typical boating area.

Maintenance And Accessories

Look for engines with accessible spark plugs, easy throttle controls, and simple maintenance routines. CDI ignition provides quick starts. Regular checks on water cooling, impeller condition, and propeller integrity help maximize lifespan and performance.

Weight And Portability

Weighing factors influence handling on shore and ease of transport. Lighter engines are easier to mount, dismount, and store, but ensure they still deliver sufficient power for your boat size and load.

Safety And Handling

Ensure you understand safe mounting, trim/tilt options, and emergency shutoffs. Anti-siphon measures, flameout safeguards, and robust throttle controls contribute to safer operation on varying water conditions.

Compatibility And Installation

Verify mounting patterns, propeller compatibility, and alignment with your jon boat’s transom. Some motors include reverse or tilt features that improve handling in tight spaces or currents.

FAQ

  1. What size gas motor is best for a 13–19 ft jon boat?

    Typically, 3.5–9 hp is common, depending on boat weight, water conditions, and desired speed. Larger boats in this range benefit from higher power options like 7–9 hp.

  2. Are 2-stroke motors still a good choice?

    They deliver more power per weight and are lighter, but require oil mixing and may produce more smoke and fuel consumption. Consider emissions, fuel availability, and maintenance capacity when choosing.

  3. Is air-cooled or water-cooled better for jon boats?

    Air cooling is simpler and lighter, suitable for light use. Water cooling supports longer runs and hotter conditions but adds complexity. Choose based on typical trip duration and climate.

  4. Can I upgrade from a smaller motor to a bigger one later?

    Yes, but ensure your transom can support the heavier motor and that the fuel system and propeller match the boat’s weight and balance.

  5. What maintenance is essential for gas outboard motors?

    Regularly check cooling paths, change oil (for four-strokes), inspect spark plugs, clean or replace fuel filters, and inspect the propeller for damage.

  6. Do these motors require seasonal storage prep?

    Yes. Flush the cooling system, drain fuel when storing long-term, and store in a dry place to prevent corrosion.
