Running dual engines on a boat has several advantages. Firstly, in the event of an engine breakdown, the second engine can be used as a backup to get back home safely. Additionally, having two engines provides more power and manoeuvrability, making it easier to navigate tight spaces. The weight of the twin engines also increases the boat's stability, reducing movement while fishing, cruising, or anchored. Furthermore, dual engines allow the boat to travel at higher top speeds for longer distances without over-stressing a single engine. While there are additional costs associated with twin engines, the benefits of improved performance, safety, and redundancy make them a popular choice for boat owners.
Why run dual engines on a boat?
| Characteristics | Values |
|---|---|
| Redundancy | If one engine breaks down, the other can be used to get back home |
| Reliability | Two engines are better protected against mechanical breakdowns and hitting submerged rocks or stumps |
| Speed | Two smaller engines can often provide more horsepower than a single larger engine, resulting in higher top speeds |
| Stress | Each engine only needs to provide half the power, reducing the stress on each engine |
| Maneuverability | Twin engines work together to provide directional thrust vectors, allowing for easier maneuvering, especially at low speeds |
| Stability | The weight of twin engines is spread across the width of the boat, providing greater stability |
| Resale value | Boats with more power tend to have better resale value |

Safety: dual engines can prevent a boat from being dead in the water if one engine fails
Safety is a key consideration when boating, and dual engines can provide a crucial backup in the event of engine failure. If one engine fails, the other can serve as a "get home" engine, allowing the boat to continue operating and preventing it from being stranded in the water. This redundancy can be a lifesaver in emergency situations, providing peace of mind and a means of returning to port safely.
The reliability of outboard motors has improved significantly over the years, but issues can still arise, such as fuel problems or mechanical breakdowns. With a single engine, any problem could leave the boat dead in the water, at the mercy of the currents and potentially in danger. However, with dual engines, even if one fails, the other can keep the boat operational until assistance arrives or the boat reaches shore.
In addition to engine failure, there are other potential hazards that a dual-engine setup can help mitigate. For example, striking a submerged object like a rock or stump could damage a single engine, but with two engines, the chances of both being affected simultaneously are much lower. This added layer of protection can make all the difference in ensuring the safety of the crew and the vessel.
The benefits of dual engines extend beyond simply having a backup. With two engines, the overall stress on each engine is reduced, as they share the burden of powering the boat. This means that dual engines are less likely to be pushed to their maximum capacity, reducing the risk of overheating or over-stressing, which could lead to a breakdown.
When it comes to safety on the water, redundancy and reliability are crucial. Dual engines on a boat provide that extra level of security, ensuring that even if one engine fails, the boat can still make it back to port. This added measure of safety is a significant advantage, especially for those who frequently venture out on long-distance or open-water voyages, where assistance may be far away.

Redundancy: two engines mean one can fail and the boat can still operate
Running dual engines on a boat provides redundancy, which is an important safety feature. Having two engines means that if one fails, the other can keep the boat operational. This can be a lifesaver in an emergency situation, allowing the boat to return to port or shore.
In the case of engine failure, a twin-engine boat can still function and get you home. This is especially useful if you are far from your home port, as it was for the crew of a Boston Whaler 320 Outrage, which experienced engine failure 50 miles from home. The boat was able to return to port using the remaining engine, although it took three hours, rather than the usual one hour and fifteen minutes.
While it is possible to operate a twin-engine boat with just one engine, it is not recommended for long periods. The boat will not perform as efficiently, and the stress on the single engine will be much higher. It is also more difficult to steer with only one engine, and the boat may pull to one side.
Having two engines means that if one fails, you still have power and can get home faster than if you had to rely on a single engine. This redundancy is a great safety feature and can give peace of mind when out on the water.

Maneuverability: dual engines allow for spinning the boat and turning at sharp angles
A boat with dual engines is considerably easier to manoeuvre than a single-engine setup. Dual engines work together as a team, allowing for directional thrust vectors that enable the boat to spin in place and turn at extremely sharp angles. This capability is particularly useful when docking, as it allows the boat to be manoeuvred into tight spaces with ease.
When approaching a slip at a 90-degree angle, once the middle of the boat is aligned with the middle of the slip, the engines can be opposed to get the boat spinning. The bow will move in the direction of the throttle shifted into reverse. For example, shifting the starboard throttle into forward and the port throttle into reverse will cause the bow to spin to port.
In addition to spinning, dual engines provide the ability to "walk" the boat sideways at low speeds, making it easier to sidle right up to the dock. This manoeuvrability is especially advantageous when fishing, cruising, or anchoring in tight spaces.
Furthermore, with dual engines, there is no need to swing the stern out when turning at low speeds. This feature enhances the overall manoeuvrability of the boat and allows for precise control in various situations.
The ability to independently control the direction and thrust of each engine provides an unparalleled level of agility and responsiveness, making dual engines ideal for navigating in confined areas or performing complex manoeuvres.

Stability: the weight of two engines increases balance and reduces movement
Stability is a crucial factor in the operation of any boat, and the presence of dual engines can significantly enhance this aspect. The weight of two engines increases balance and reduces movement, making the vessel more stable on the water.
The stability offered by dual engines is particularly advantageous for activities such as fishing, cruising, or anchoring. With the engines' weight distributed across the width of the boat, a twin-engine setup provides a more stable platform, minimising movement and enhancing overall stability.
This stability is a result of the even distribution of weight across the vessel. By having two engines, the weight is spread out, reducing the strain on any single point. This balanced weight distribution helps to prevent the boat from listing to one side, ensuring a smoother and more controlled experience.
Additionally, the twin-engine configuration provides a redundancy factor. Should one engine encounter problems or fail, the other engine can keep the boat operational. This not only ensures a safer journey but also provides peace of mind, especially when venturing into remote or challenging waters.
The improved stability of dual engines also translates to better manoeuvrability. The directional thrust vectors of twin engines allow for precise control, enabling the boat to spin in place and execute sharp turns. This enhanced manoeuvrability is especially beneficial when navigating tight spaces or docking, as the boat can be easily "walked" sideways.

Resale value: a dual-engine boat will sell faster and at a higher value
A dual-engine boat will have a much better resale value than a single-engine boat. Boats with more power tend to sell faster and carry a higher value on the used boat market.
A dual-engine boat is more expensive to run and maintain than a single-engine boat, but the benefits of having two engines are significant. The upfront cost of a dual-engine boat is higher, and there are additional costs to consider, such as extra weight, rigging, controls, cables, wiring harnesses, propping, instrumentation, and labour. These costs can be nearly double that of a single-engine setup.
However, the resale value of a dual-engine boat is higher because it is a more desirable option for buyers. The boat will have increased power, manoeuvrability, stability, and redundancy with two engines. These features make a dual-engine boat a better investment, even with the higher upfront and maintenance costs.
When it comes to selling a dual-engine boat, it is important to consider the hours on each engine. Buyers will be interested in knowing if the engines have been used evenly, as this affects the resale value. It is recommended to alternate between the engines to keep the hours relatively equal.
In summary, a dual-engine boat will have a higher resale value due to its increased performance, manoeuvrability, stability, and redundancy. These features make it a more attractive option for buyers, resulting in a faster sale and a higher resale price.
