Choosing the Right Engine: A Guide to Powering Your Sport Yacht

The engine is the heart of your boat. Choosing the right one is essential, as it can significantly impact speed and power.

There are many things to consider when choosing an engine, such as its size and cylinder count. Other factors include your location and the type of water you will be sailing in.


A sport yacht is a fun and exhilarating way to spend time on the water. Whether you are a water skier or enjoy cruising, the type and size of engine you choose will significantly impact your experience.

When choosing a motor, consider the size of your boat and its weight (including passengers, fuel, and equipment). 

If you are still determining what engine size is right for you, consult your local dealer, who can recommend an appropriate engine for your boat. Be sure to discuss how you plan on using your boat so they can make recommendations based on your goals.

For example, if you are interested in water skiing, the dealer may suggest a larger motor for faster takeoff and better handling while towing waterskis. They will also be able to recommend the best propeller for your needs.


Modern sport yachts are safe, exhilarating, and fun to sail. This trend has been helped by advances in hull design and construction, powerful asymmetric spinnakers, and, most importantly, the adoption of racing-style cockpit controls. Sit low — supercar low — in the fabulous helm seat and grasp the wheel that thrusts forward with your legs resting on a pair of foot plates. Then reach down to stubby throttle heads, and you are in total control.

Fuel Efficiency

The fuel efficiency of a yacht is an important consideration, especially for long cruises. The fuel required can add up quickly, especially when the yacht has large tanks. A higher octane fuel, which resists pre-ignition better than lower grades, can increase fuel economy. Still, it’s essential always to follow the engine manufacturer’s recommendations.

A proper size propellor is also critical for fuel efficiency. A too small propellor causes the engine to rev in the red, while a too-large propeller reduces fuel economy.

On average, a well-maintained four-stroke gasoline or diesel engine burns about 0.4 pounds of fuel per hour for every unit of horsepower it produces. These figures do not consider the boat’s drag or efficiency losses through transmissions and bearings. Using auto-trim systems that constantly adjust the trim to suit sea conditions can significantly improve fuel efficiency. Also, reducing the amount of weight onboard can significantly decrease fuel consumption.


Luxury yachts aren’t self-maintenance machines; they require optimal care to last for as long as possible. You can significantly extend your boat’s lifespan by seeking regular cleaning and brightwork maintenance, adding some simple maintenance tasks to your yacht’s ‘to-do’ list, and taking an approach that prioritizes consistency rather than a rush job.
