In 2023, the marine propulsion sector in the UK, specifically for compression-ignition internal combustion piston engines of less than 200 kW, showed production figures slightly higher than the forecast for 2024, with an actual value of approximately 25 million Euros. It indicates a forecasted steady decline of less than 1% year-on-year from 2024 through 2028. This results in a compound annual growth rate (CAGR) of approximately -0.4% over the next five years, reflecting a gradual downtrend in production values.

Future trends to watch for:

Continuous technological advancements: These could either enhance engine efficiency or introduce alternative propulsion systems, affecting demand.
Regulatory impacts: Stricter environmental regulations may push for greener technologies, impacting production of traditional engines.
Market demand shifts: Global and local maritime industry changes might influence production, driven by needs for lower-power marine applications.
