Outboard vs. Sterndrive Propulsion

Outboard vs. Sterndrive Propulsion

Whether you prefer luxury and comfort or dynamism and speed, in both cases, the boat’s motorization remains the beating heart of the navigation experience.

If the ability to combine sinuous lines and spacious interiors is synonymous with versatility, how can this feature stand out relating to engines?

The answer is simple: different engine configurations.

FIM offers different engine options for 340 Regina: sterndrive (like the model presented at Genoa Boat Show 2020) and outboard to allow the clients to choose the configuration that best suits their needs.

But what distinguishes the sterndrive from the outboard? Which one to prefer?

The first difference concerns the engine’s location.

The outboard engine is a separate element from the rest of the boat, mounted on the transom with special supports.

The engine directly transmits its power to the propeller, thanks to the vertical configuration of the mechanism. It allows the adjustment of the vertical inclination (trim) according to the speed to optimize consumption.

On the other hand, the sterndrive engine houses the engine block in the engine room inside the boat, which generates the power that is transmitted, via a universal joint, to the propellers to the stern outboard unit.

Compared to an inboard configuration, the outboard propulsion allows you to modify the trim and, therefore, to vary the stern drive’s inclination to navigate in shallow water.

In terms of maintenance, outboard engines are more accessible and make it easier to intervene. Simultaneously, sterndrive propulsion requires more attention in identifying any failure and more skills for repair.

Undoubtedly, by purchasing the boat directly from the shipyard, the owners have access to a maintenance service carried out by those who best know the yacht, making the issue of repairs a secondary concern.

Until a few years ago, sterndrive engines were always better performing than outboards on longer boats, at the expense of less maneuverability due to the bulk of having the engine block on board.

Today, advances in technology and design have significantly softened this differentiation, with more powerful outboards and smaller, lighter sterndrive engine blocks.

However, those who prefer a more dynamic line will indeed choose the outboard thanks to its better acceleration and top speed.

On the other hand, those who want to use the boat mainly at cruising speed will prefer the sterndrive, thanks to the better set-up and lower consumption.

The external location of an outboard engine facilitates refitting, while the internal one of the sterndrives allows for quieter navigation and has no space on the transom.

In short, the choice depends a lot on individual preferences and the intended use of the boat, but both engines offer an unforgettable sailing experience.
