As of May 2023, the National Marine Manufacturers Association reported a substantial 36% rise in annual economic activity within the recreational boating sector, reaching $230 billion. Furthermore, there was a notable 14% increase in jobs associated with the recreational maritime industry, totaling 812,000 in 2023. This data underscores the significant impact of increasing recreational boating activities as a driving force behind the growth of the inboard engine market.

The burgeoning tourism sector is also expected to contribute to the expansion of the inboard engine market. The tourism sector, encompassing various travel-related activities and services, relies on inboard engines to power boats and vessels for scenic tours, transport, and other water-based activities. In November 2023, the UK's Office of National Statistics reported a growth in overseas tourists visiting the UK, increasing from 2.8 million visits in May 2022 to 3 million visits in June 2022. These tourists spent a total of $3.42 billion (£2.7 billion) in the UK. The consistent growth in tourism serves as a key driver for the inboard engine market, as reliable and efficient inboard engines play a crucial role in ensuring safety and performance in water-based tourism activities.

Major companies in the inboard engines market are focusing on advanced solutions, such as marine engines, to enhance vessel performance, minimize environmental impact, and ensure compliance with stringent regulatory standards. A marine engine is specifically designed for use in boats and ships, engineered to operate efficiently and reliably in marine environments that present unique challenges, including varying loads, exposure to saltwater, and a need for durability. For example, in September 2024, Scania AB, a Sweden-based manufacturing firm, unveiled its new DI13 13-liter marine engine at the SMM maritime trade fair in Hamburg, representing a significant advancement in marine technology. This engine is designed for both propulsion and auxiliary applications, providing a power range from 257 to 772 kW (approximately 350 to 1050 HP) and boasts an 8% improvement in fuel efficiency compared to earlier models. It meets IMO Tier III emissions standards and is compatible with biodiesel and HVO fuels, showcasing Scania's dedication to sustainability.

Major players in the inboard engine market are adopting a strategic partnership approach to bolster their offerings and drive innovation. Strategic partnerships involve companies leveraging each other's strengths and resources to achieve mutual benefits and success. A case in point is the partnership established in June 2023 between Wartsila Corporation, a US-based provider of complete life-cycle marine and energy solutions and services, and Qtagg, a Swedish-based green tech company. This collaboration aims to introduce an innovative retrofit solution for their marine engine governor system. The marine governor systems by ANCS regulate and control engine speed, managing fuel supply under various operating conditions. The retrofit solution integrates digital engine governors and advanced AI eco-driving systems, reducing fuel consumption and emissions while significantly enhancing operating efficiency. This strategic partnership highlights the industry's commitment to collaborative efforts and innovation in the inboard engine market.

An inboard engine is a type of four-stroke engine designed to propel a drive shaft through the bottom of a hull, connecting to a propeller at the opposite end. These engines are highly favored for water-based activities such as wakeboarding and waterskiing due to their exceptional wake control, robust towing capacity, and open transom, allowing for convenient towing rope attachment.

Inboard engines draw power from various sources, including diesel, electric, gasoline, and other fuel types. Diesel, a heavy oil utilized as fuel in vehicles and trains with diesel engines, is one of the available power sources. These engines come in varying power levels categorized as low, medium, and high, featuring different ignition mechanisms such as electric and manual. The types of engines commonly found in inboard systems include internal combustion (IC) engines and electric engines, which serve diverse purposes in commercial and boating applications, among others.
