Before ordering a 8 HP outboard
The listed Mercury models have distinct 8MH, 8MLH, 8EH and 8ELH codes. Compare the full code and product description rather than choosing by horsepower alone.
| Compare | What to confirm |
|---|---|
| Exact model | Compare the complete 8 HP code, not just the horsepower. |
| Starting and shaft | Check the starting system and stated shaft configuration in the individual listing. |
| Controls and equipment | Confirm what is supplied before comparing the total purchase. |
Browse outboards by horsepower or compare portable outboard listings. Send your boat details and full model code to confirm the configuration before ordering.
Choosing a 8 HP outboard
- Shaft length: match it to your transom height: about 15″ for a short shaft, 20″ for a long shaft and 25″ for an extra-long shaft. In the model code, S means short, L long, and X, XL or UL extra-long. See our outboard shaft length guide.
- Tiller or remote: tiller models steer and throttle from the handle on the motor. Remote models are steered from a console and need control cables, a control box and steering.
- Owning one: what size outboard do I need? · electric vs pull start · break-in procedure · won’t start · kill switch and lanyard · spark plugs · overheating · won’t idle · loses power at full throttle · trim not working · milky lower unit oil · how to flush it · tilt and trim fluid · stiff steering cable · anodes · fuel lines · tachometer settings · thermostat · ignition switch · trim gauge · won’t go into gear · how many hours is a lot.
