Authorized Mercury service · Kartal, Istanbul
We open Mercury's maintenance schedule model by model for Mercury outboards and MerCruiser sterndrives. Every procedure page states separately who does each step, what is done, why it is needed and how; the parts list comes with live price and stock, oil and gearcase capacities are model-specific, and Mercury's official videos and the matching owner's manual section sit on the same page. The source document and page number are printed at the bottom of every page.

The list is grouped by family; each card shows how many procedure pages the model has. Pages are prepared per model and serial range. If you are not sure which model you have, the serial number box above looks it up in the Mercury registry.
Model and procedure pages are in English; the step narratives on them come from the workshop records and are in Turkish for now. Schedules, parts lists, prices and capacities read the same in any language.

Maintenance schedule
The interval rule is the same on every model: engine hours or calendar, whichever comes first. Engines run in salt or brackish water get their anodes, spark plugs and lubrication points checked more often. The cards are the general frame; steps and parts lists vary by model and are written on the model page.
first 20 engine hours · on 35 models
What is done: As soon as break-in ends the gearcase lube is changed and the engine oil and filter renewed per model; bolt torques, cable and hose connections and the propeller nut are checked.
Why: New gears shed the most metal in the first hours; a gearcase that keeps running on that lube later turns noisy and leaks at the seals. This service is also the first line of the warranty record.
Steps and parts for your model →100 hours or once a year, whichever first · on 37 models
What is done: Engine oil and filter, fuel filter, gearcase lube, anodes, spark plug check, propeller shaft greasing, thermostat and cooling water outlet check.
Why: By 100 hours the oil has turned acidic with combustion by-products and attacks the bearings; in salt water an anode dissolves in a season and hands its job to the aluminum housing. Done before the season, problems are caught before you leave the dock.
Steps and parts for your model →300 hours or every three years · on 37 models
What is done: On top of the 100-hour items the water pump impeller and spark plugs are replaced; belts, fuel lines and harness connections are inspected per model.
Why: Impeller rubber hardens over three seasons and loses vanes; a lost vane is invisible at first but cooling flow drops and the engine runs hot. These items age by time, not hours.
Steps and parts for your model →end of season, before the first frost · on 35 models
What is done: Freshwater flush, fuel stabilizer, fogging oil in the cylinders, water check in the gearcase lube, fuel filter and anode renewal, battery removed and kept on charge.
Why: Water left in the block or gearcase expands when it freezes and cracks the casting; frost damage is outside warranty. Ethanol fuel separates within months and clogs the injectors. Winterization prevents both before next season starts.
Steps and parts for your model →before every trip · on 35 models
What is done: Oil level, fuel line and priming, lanyard stop switch, damage on propeller and gearcase, play in trim and steering; once running, the cooling water tell-tale stream.
Why: Most breakdowns at sea come from things visible in five minutes ashore, like a loose connection or a damaged propeller. Without the tell-tale stream the engine overheats within minutes.
Steps and parts for your model →after every trip · on 35 models
What is done: After salt or brackish water: flush the engine with fresh water, rinse the exterior, let the gearcase drain in the upright position, close the fuel valve.
Why: Salt left in the cooling passages crystallizes as it dries and narrows the thermostat and water passages. On an engine that is not flushed regularly the 300-hour service bill grows.
Steps and parts for your model →What's on a page
Steps. Each step under six headings: who does it, what is done, why it is needed, how it is done, what to watch for, what is required. Dealer-only steps carry a badge; you tick steps off as you go.
Parts list. Mercury part number, live price (US$ list, VAT excluded; ₺ equivalent at the Turkish central bank rate) and stock status. "If needed" items stay outside the total; the list goes to the cart in one tap.
Capacities. Engine oil and gearcase lube quantity, the specification Mercury requires, the package part number, with the source page.
Exploded drawings. The part a step touches is marked on the Mercury catalog drawing; clicking the mark opens the catalog line and its price.
Videos. Mercury Marine's and Quicksilver's official walkthroughs sit next to the step; Merkür's own Turkish recordings take precedence as they are produced.
Owner's manual and source. The relevant manual section opens as a separate PDF; the source document and page number are printed at the bottom of every page. Where a step's narrative is not yet approved, no technician note is published and an "explanation in preparation" line appears instead.
Yourself / authorized dealer
Pre- and post-use checks, freshwater flushing, anode and propeller checks, draining water from the fuel filter bowl, cleaning battery terminals. Engine oil, filter and gearcase lube changes are also possible; the step pages give the torque value and capacity. During the warranty period these services must be recorded at an authorized dealer.
FAQ
Mercury's schedule has three tiers: a first service at 20 hours, periodic maintenance every 100 hours or once a year, and replacement of wear parts every 300 hours or every three years. Whichever comes first, hours or calendar, sets the date. Engines run in salt or brackish water get their anodes, spark plugs and lubrication points checked more often. The full list for your model is on its model page.
Mercury's warranty terms require maintenance at the manual's intervals, on record; the 20-hour service is the first line of that record. A failure caused by skipped maintenance can be rejected. The warranty document supplied with your engine is the binding text; service done at the Kartal workshop is entered into the Mercury system by serial number.
Pre- and post-use checks, freshwater flushing, anode and propeller checks and draining water from the fuel filter bowl are the owner's jobs; the pages mark these steps with a 'boat owner' badge. Engine oil, filter and gearcase lube changes are also possible, but during the warranty period the service must be recorded at an authorized dealer. Steps that need torque values, diagnostic software or special tools carry the 'authorized dealer' badge.
Every model page has a capacity table: engine oil and gearcase lube quantity, the specification Mercury requires and the Mercury part number of the package. Values come from the Mercury owner's manual and are printed with the page number; the Merkür service team verifies them.
Prices are Mercury US$ list prices, VAT excluded; the ₺ equivalent is calculated at the day's Turkish central bank rate. The site does not sell directly: you add items to the cart and send a quote request; our team confirms price, stock and delivery by SMS. Labor hours are on the plan page; the amount is given in the maintenance quote.
On an outboard the serial number is on the plate on the transom bracket; on a MerCruiser it is on labels on the engine block and the drive. The letter O is written as zero. Typed into the box on this page, it finds the model, model code and the parts catalog by serial range in the Mercury registry.
After the engine's last use of the season, before the first frost. Winterization adds stabilizer to the fuel, fogs the cylinders with protective oil, flushes and drains the cooling system with fresh water, and checks the gearcase lube for water. Leaving water and old fuel inside the engine over winter means a cracked block and clogged injectors.
Yes. Approved plans for the MerCruiser 4.5L and 6.2L engines, the Bravo Three drive and the transom assembly are in the list. Engine, drive and transom are separate service models; each page states in its title which scope its plan covers.
Guide
Each article covers a single question; the figures come from the Mercury manual or the approved maintenance plan with the source page, and link to your model's procedure page. Guide articles are currently in Turkish.

Technical page
These pages speak to the boat owner in who-what-why language. The full technical form of the same information lives on a separate page in table layout: step order and duration, sub-steps, torque and capacity values, tool and consumable list, catalog drawing position numbers, labor hours, source document and page. The Technical page link at the top right of every model and procedure page opens that page's technical form; it is printable.
Internal technician notes and work-order instructions are not published on the technical page either; only the full form of the narrative approved by the Merkür team is shown.
