Anchoring Reliability: Material Advancements in Engine Sealing Systems

Marine environments are among the harshest for mechanical systems. Seals used in recreational boat engines must endure high pressure, salt, UV exposure, and fluctuating temperatures. Recent advances in material science are helping address these challenges.
According to Stratview Research, the recreational boat engine seals market size was USD 99.0 million in 2023 and is likely to grow at a healthy CAGR of 2.2% during 2024-2030 to reach USD 114 million in 2030.
