Product features and details

The product is uniquely identified by name and codes, useful both during purchase and in spare parts warehouse management.

• Spark plug model: NGK BPR7HS
• Supplier: Osculati S.r.l.
• Supplier product code: 47.558.46

Factory-fitted (catalog information)

According to the available description, this spark plug is factory-installed on engines of the following brands:

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

Important note: presence in the list does not replace the precise verification of compatibility.

Before installation, it is always advisable to check the engine manual or the currently installed spark plug.

Quick identification and spare parts management

To reduce errors during reorder, it is good practice to always use at least one of the following:

• the code NGK BPR7HS (spark plug model identification);
• the Osculati code 47.558.46 (reference useful for orders and quotes).

This dual identification is particularly useful for workshops, shipyards, and boat owners who want to standardize the onboard spare parts list and simplify logistics.

Typical applications in the nautical field

The spark plug is a consumable component that falls under the scheduled maintenance of the ignition system. In the nautical field, where operating conditions can vary (humidity, salt spray, periods of inactivity), periodic replacement of spark plugs is one of the most common activities during seasonal checks.

When it may be useful to intervene

Without going into specific diagnoses, spark plug replacement is often considered during:

• routine servicing and checks of the outboard;
• storage and preparation for the season;
• ignition system checks in case of irregular operation (to be confirmed with appropriate checks);
• restoration after long periods of inactivity, when it is preferable to restart with consumable components in good condition.

Usage contexts

This spark plug is indicated as a spare part for engines of brands widely present in the sector. It can therefore be included in:

• spare parts supplies for assistance and maintenance;
• onboard stocks for scheduled interventions;
• spare parts management for fleets and rentals, where component standardization is an operational advantage.

Advantages for maintenance and procurement

Recognizable and easy-to-order spare part

The presence of a clear code (BPR7HS) and a supplier reference (47.558.46) helps to:

• reduce ambiguity between similar products;
• speed up quote requests and reorders;
• maintain consistency between installed spare parts and warehouse stock.

Suitable for regular maintenance plans

Spark plugs are among the components typically replaced during maintenance. Having the correct spare available allows for more continuous planning of interventions, especially during peak season or when the boat needs to be ready for use.

Installation indication on popular brands

The fact that it is listed as standard equipment on several brands (Mariner, Yamaha, Suzuki, Mercury, Tohatsu, Selva, and Honda) makes it an item of interest for those working on diverse engines. However, verifying the specific model remains essential.

Usage and operational notes

Replacing a spark plug is generally a simple operation but must be done carefully and in accordance with the engine manufacturer's instructions. If in doubt, it is advisable to rely on qualified personnel.

Checks before purchase

• Check the code of the currently installed spark plug and compare it with NGK BPR7HS.
• Consult the manual of the engine to confirm the correct model specified by the manufacturer.
• If ordering through the supplier catalog, use the Osculati code 47.558.46 to avoid errors.

Notes for installation and maintenance

• Work with the engine off and under safe conditions, avoiding accidental starts.
• During replacement, check the general condition of the removed spark plug: it can be useful for an overall assessment of performance (to be interpreted according to proper procedures).
• Avoid over-tightening: follow the engine manufacturer's instructions or workshop procedures.

Practical advice for spare parts management

If you manage multiple engines or a small fleet, systematically noting engine brand/model and spark plug code installed helps reduce downtime and makes scheduled maintenance more efficient.
