Petrol vs Electric Outboard — Why More Owners Are Switching
| Feature | Haswing Ultima 3.0HP Electric | Typical 3HP Petrol Outboard |
|---|---|---|
| Noise | Whisper-quiet (~55dB) | Loud engine + vibration |
| Fuel / Smell | No fuel, no fumes | Fuel mixing, fumes, storage |
| Maintenance | Low-maintenance electric drive | Servicing, oil, carb issues |
| Start / Ease | Instant power, simple controls | Pull-start, warm-up, choke |
| Where it shines | Tenders, inflatables, quiet waterways | Longer continuous running needs |
| Best buyer fit | Quiet, clean, easy boating | Max range with fuel onboard |
Bottom line: If your use is tender duties, marina transfers, lakes/rivers and calm coastal runs, electric is often the better ownership experience.
