Engine maintenance

(409 products)

A well-maintained boat engine ensures safety on the water and extends the lifespan of your propulsion unit. Whether outboard or inboard, regular maintenance protects against breakdowns and reduces costly repairs. In this category, you'll find everything you need for professional engine maintenance.

  • Maintenance for fresh and salt water use

    A boat engine operated in saltwater is particularly susceptible to corrosion and requires more intensive maintenance. This includes a thorough freshwater rinse after every trip and the use of suitable corrosion protection agents. For freshwater, a seasonal overhaul is usually sufficient, but even then, the engine should be checked regularly.

  • Check cooling system and wear parts

    The cooling system is essential for operation. Annual inspection and timely replacement of impellers, hoses, and seals are recommended. For longer trips, you should always have spare parts such as impellers, filters, and seals readily available on board.

  • Accessories for engine maintenance

    In the awn online shop, you'll find suitable tools, sealants, lubricants, and engine care products—ideal for preparing for the season or for carrying out small repairs on the go. Practical spare parts boxes with screws, nuts, and gaskets are also part of the basic on-board equipment.

    Check spark plugs and drive belts and replace if necessary
    Check fuel lines for leaks
