The NGK BP6HS spark plug offered by Osculati (supplier code 47.558.13) is a spare part designed for routine maintenance of outboard engines and marine engines where this model is specified.

Product features and details

Identification and references

• Product: NGK BP6HS Spark Plug
• Supplier: Osculati S.r.l.
• Supplier product code: 47.558.13

When managing spare parts for engines (especially in a marine context), identification by code is often the fastest method to avoid errors. The reference 47.558.13 allows the product to be traced back to the Osculati catalog and compared with your spare parts list or the engine manual instructions.

Maintenance spare part

The spark plug is among the components typically subject to replacement during scheduled maintenance or in case of interventions on ignition and engine operation. In general, a correct and good condition spark plug helps maintain smooth starting and combustion, reducing the risk of irregularities related to wear or deposits.

Note: to ensure the correct choice, it is always advisable to verify the model required by the engine manufacturer or your reference mechanic, especially if the engine has undergone updates, previous replacements, or particular configurations.

Typical applications (as described)

According to the available description, these spark plugs are fitted as standard on engines of various brands, including:

• Mariner
• Yamaha
• Suzuki
• Mercury
• Tohatsu
• Selva
• Honda

This indication is useful as a guideline but does not replace precise verification on your own engine model: within the same brand, there may be variants and different series that require different spark plugs. For this reason, before purchase or installation, it is good practice to check the spark plug code required or the spare part code indicated in the technical documentation.

Advantages for purchase in the marine field

Recognizable and easily orderable spare part

The clarity of references is a concrete advantage: the combination of spark plug name (NGK BP6HS) and Osculati code 47.558.13 helps reduce ambiguity and manage reorders and replacements more quickly, especially when working on multiple boats or different engines.

Suitable for routine maintenance

Replacing the spark plug is a common operation in the workshop and storage, and is among the interventions often carried out before the season or after periods of inactivity. Having the correct spare part available allows planning maintenance without improvisation, keeping the engine in regular operating conditions.

Usage indication on popular brands

The fact that the description reports the standard use on widely present brands in the nautical sector (such as those listed) makes this item particularly interesting for those managing spare parts with a “stock” logic or for those who want a known reference to compare with their own configuration.

Usage and operational notes

Checks before replacement

• Check the required code from the engine manual or technical documentation.
• Compare the code with your spare parts list (in this case: 47.558.13).
• If you are replacing an already installed spark plug, check the marking on the removed spark plug and compare it with BP6HS.

In case of doubts about compatibility, it is preferable to stop at the documentary check or ask for technical support: an incorrect spark plug can lead to irregular operation or starting difficulties.

Good maintenance practices

During maintenance, in addition to replacement, it can be useful to inspect the removed spark plug to identify any signs of abnormal operation (for example deposits or obvious wear). This type of check, while not replacing a diagnosis, can help understand if the ignition system and fuel supply are working properly.

For an orderly and repeatable intervention, it is advisable to work with appropriate tools and follow the engine manufacturer's instructions regarding assembly and checks. If the boat is used sporadically or under demanding conditions, planning maintenance in advance helps reduce unplanned downtime.

Note on compatibility and usage responsibility

The indications on brands (Mariner, Yamaha, Suzuki, Mercury, Tohatsu, Selva, and Honda) represent a reference reported in the available description. Since applications may vary depending on the model, year, and engine configuration, the final choice must be made based on the manufacturer's specifications or the originally installed spare part.
