Inboard Engines Global Market Report 2026

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.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report's Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs on marine-grade steel, engine blocks, electronic control units, and propulsion components are increasing production and maintenance costs for inboard engines. North America and Europe are most affected due to reliance on imported precision engine parts, while Asia-Pacific manufacturers face export pricing pressure. These tariffs raise boat manufacturing costs and slow engine upgrades. However, they are encouraging regional engine assembly, supplier localization, and innovation in fuel-efficient and hybrid-compatible inboard engine platforms.

Major trends in the forecast period include growth of recreational water sports demand, preference for high torque marine engines, integration of noise and vibration reduction, shift toward fuel efficient designs, expansion of luxury and sports boats.

The expanding tourism sector is expected to drive the growth of the inboard engine market in the coming years. The tourism sector includes all activities and services related to travel, accommodations, attractions, and visitor experiences for leisure, business, or other purposes, significantly contributing to regional economies and cultural exchange. Inboard engines are used to power boats and vessels for scenic tours and transportation, offering reliability and safety in water-based activities due to their efficiency and consistent performance. For example, in February 2025, according to the United States Bureau of Economic Analysis, a US federal statistical agency, the travel and tourism industry's real output, representing goods and services sold directly to visitors, grew by 7.0% in 2023, following a 20.8% increase in 2022. In comparison, the overall U.S. economy, measured by real GDP, expanded by 2.9% in 2023 after a 2.5% rise in 2022. As a result, the growing tourism sector is supporting the growth of the inboard engine market.

Key players in the inboard engines market are focusing on advanced solutions, such as marine engines, to enhance vessel performance, reduce environmental impact, and comply with stringent regulatory standards. A marine engine is specifically designed for boats and ships, engineered to operate efficiently and reliably in marine environments that present challenges such as varying loads, saltwater exposure, and durability requirements. For instance, in September 2024, Scania AB, a Sweden-based manufacturer, launched its new DI13 13-liter marine engine at the SMM maritime trade fair in Hamburg, marking a significant technological advancement. This engine, suitable for both propulsion and auxiliary applications, offers a power range of 257 to 772 kW (approximately 350 to 1050 HP) and delivers an 8% improvement in fuel efficiency compared to previous models. It meets IMO Tier III emissions standards and is compatible with biodiesel and HVO fuels, demonstrating Scania's commitment to sustainability.
