The morning fog clings to the water as you pull the starter cord on your inflatable boat. You need just enough propulsion to reach that quiet cove before the sun hits its peak.
Finding the right power for your craft changes how you spend your time on the water. These Best Small Outboard Motors provide the reliable thrust you need without the unnecessary bulk of a massive engine.
Key Takeaways
- Prioritize a water-cooled engine if you plan to run your motor at high throttle for extended periods on the lake.
- Match the shaft length specifically to your boat transom height to avoid cavitation issues or poor handling.
- Choose a two-stroke engine if you prioritize a higher power to weight ratio and simpler maintenance.
- Verify the total weight of the unit to ensure your boat can handle the transom stress while maintaining proper balance.
- Check that the ignition system uses a reliable design like CDI for consistent cold starting in damp conditions.

Frequently Asked Questions
Do I need to flush my outboard after using it in saltwater?
Yes, you must flush the engine with fresh water after every saltwater trip. Most motors feature a flush port where you can attach a garden hose to clear salt deposits from the cooling passages. This prevents internal corrosion that can destroy an engine from the inside out.
How often should I change the gear oil?
Plan to change your gear oil at least once every season or every 100 hours of operation. Fresh oil ensures the internal gears stay lubricated and free of water intrusion. If the drained oil looks milky, you likely have a damaged seal that needs immediate repair.
Can I store my outboard motor on its side?
Only store your motor on the side specified in the owner manual. Many engines have specific oil pathways that will leak or foul the spark plugs if laid down incorrectly. If you are unsure, keeping the motor in an upright position on a stand is the safest choice.
What is the benefit of a propeller pitch change?
Changing the propeller pitch allows you to fine-tune how the engine hits its maximum RPM range. A lower pitch helps the boat plane faster with a heavy load. A higher pitch increases your top speed when carrying a lighter weight.
Why does my motor stall when I shift into gear?
Stalling during a shift often points to an idle speed that is set too low. Adjusting the idle screw can often solve the problem, but check the throttle linkage for any slack first. If the issue persists, your spark plugs might be fouled and in need of replacement.
