Boats & Motor

Ideally, the manufacturer/model, year of manufacture or generation, and—if available—the item, part, or serial number. Depending on the subcategory, the following are also important: tank technology (thread, connection type, hose diameter), control/switchgear (cable length, connectors/connection standard), operating fluids (specification/approval). The more precise your reference data, the lower the risk of ordering the wrong part.

Many parts are specific to a generation or system (e.g., propellers, cables, remote controls, mounts). Check the exact model designation and version. Whenever possible, order based on a compatibility list or exploded view rather than “by appearance.” If you provide us with the model/serial number, we can narrow down the matching parts with a high degree of reliability.

Measure the actual route from the control station to the motor/gearbox, account for bends with a large radius, and allow some extra length for movement (motor trim/steering angle). Cables that are too short put strain on the mechanism; cables that are too long increase friction and can make the shifting feel “spongy.” If the old cable is still available: reading the markings/length and replacing it 1:1 is often the safest approach.

The decisive factors are system type (mechanical or hydraulic), connection standard (end fittings, shift box, motor linkage), and the design for the motor/drive. First, identify the existing parts (nameplate/part number, photos of the end fittings). Then select components that explicitly match the standard and load class.

Important factors include hose diameter, thread/connection type, flow rate (if applicable), and whether a water separator is required. A suitable filter protects against failures caused by dirt or water—particularly relevant for modern injection systems. Also ensure a clean, leak-free installation and use appropriate hose clamps.

Do not use “just any oil”: Choose according to manufacturer approval and specifications (viscosity, API/ACEA, marine-specific requirements if applicable, and transmission oil grade). The relevant specifications are listed in the engine/transmission owner’s manual. Incorrect specifications can increase wear, damage seals, and significantly shorten service life.

Marine greases are useful for mechanisms exposed to salt water (e.g., joints, bearings) if the manufacturer recommends them. When lubricating, the rule is often: less is more—too much grease attracts dirt. Use additives only if they are expressly approved: incompatible mixtures can, in the worst case, damage materials and seals.

Distinguish between the internal cooling circuit (antifreeze according to manufacturer’s specifications, material compatibility, e.g., for aluminum/alloys) and the seawater circuit (different agents/applications apply here). Use cleaners/descaling agents only as directed to avoid damaging seals, metals, or pumps—especially during winter storage, when agents can remain in contact for longer periods.

Pads/mats are quick and clean for small leaks (refueling, oil changes). Granules are suitable for larger quantities and uneven areas such as the bilge or engine compartment. Ensure high absorbency, safe storage on board, and proper disposal as contaminated waste.

For function- or safety-critical parts (e.g., system-specific components in electric motors or certain engine attachments), original parts reduce the risk of fitment issues. For universal consumables (oils, binders, cleaners), the specification is usually more important than the brand—the key is that the approvals and operating conditions are correct.
