Inboard vs Outboard Motors
By Mike Chudd on December 11, 2020
When choosing an engine for your new boat, there are many factors to consider, such as power output, ease of maintenance, weight, drag, longevity, and more. These factors vary depending on whether you choose an inboard or outboard motor. We have put together a brief guide to help you understand what you need to know when deciding what kind of engine to go with.
- Advantages of Inboard: Motors Inboard motors offer excellent fuel efficiency due to their weight-to-power ratio, resulting in better fuel economy when compared to a similar outboard motor. In addition, inboards are easier to maneuver at low speed and are safer than outboards since the fuel tank is inside the hull and the engine is more securely contained within the boat.
- Disadvantages of Inboard: Motors Inboard motors cannot be removed from the boat, making maintenance more challenging and expensive. They are also susceptible to corrosion and damage, especially from salt water, and take up interior space in the boat. Inboard motors are also more expensive than outboard motors, which can be a deal breaker for some buyers.
- Advantages of Outboard: Motors Outboard motors can be removed from the boat for easy maintenance and storage, making repairs less expensive and more accessible. They are significantly less expensive than inboard motors and do not take up interior space in the boat. Outboards also offer quick handling, a tighter turn radius, and maneuverability at low speeds.
- Disadvantages of Outboard: Motors Outboard motors may not have the torque to handle larger boats, and may lead to cavitation in high waves. They are noisier than inboard motors, and older models (especially two-stroke varieties) can be smoky and have an awkwardly placed gas tank.
Of course, these are only a few of the things you need to consider when looking at whether to buy an inboard or outboard motor. Most of the rest of your considerations will come down to practical questions, aesthetics, or budget.
