-
Injection and feed pump parts
-
Flame filters & fuel filters
-
Carburetors & repair kits
A constant and clean fuel supply is essential for engine running, performance and efficiency.
Cooling & seawater system spare parts
The thermal stability of the engine includes
-
Seawater pumps & impeller repair kits
-
Water and oil coolers
-
Heat exchangers & gaskets
-
Thermostats + gasket sets
These parts ensure cooling water circulation, prevent overheating and protect engine components.
Electrics & starter/generator
Electrical components for starting, charging and control:
-
Starter / starter motors
-
Alternators / generators
-
Sensors & encoders (temperature, pressure, speed)
-
Cables, plugs & electrical system components
Stable electrics ensure safe starting, clean signal transmission and reliable power supply.
Control system, sensors & encoders
Measurement and control technology includes:
-
Temperature and pressure sensors
-
Speed sensors
-

-
Control cables, switch boxes & control cable technology
Precise data is the basis for engine control, diagnostics and safety.
Gearboxes, gaskets & gasket sets
Includes:
-
Transmission seal kits & oil seals
-
Transmission Seal Kits
-
Seals for Saildrive / Z-drive
Clean sealing prevents oil or water loss and protects bearings and gears.
Maintenance kits & service sets
For scheduled maintenance and service:
-
Original service kits incl. filters, seals, O-rings
-
Complete packages according to operating hours
-
Maintenance kits for seasonal service
Service kits simplify maintenance, save time and reduce the risk of incorrect orders.
Selection by reference, engine & year of manufacture
The following criteria are decisive for the right choice of spare parts:
-
OEM reference number
-
Engine or engine type
-
Year of manufacture and serial number
-
Type of use (freshwater/saltwater, leisure/professional)
A structured comparison minimizes incorrect orders.
Installation and service instructions
General installation guidelines:
-
Disconnect the battery before carrying out any electrical work
-
Mark & remove old parts
-
Install new parts cleanly
-
Comply with OEM torque specifications
-
Function test after installation
These basic rules ensure permanent function and operational safety.
