Not sure which part fits your engine? Start with the engine manufacturer, horsepower, model number, serial number, and year whenever available.
Our OEM parts lookup lets you view factory parts diagrams and identify the original part number for many popular outboard engines. Once you have the OEM number, search Pro Marine to find available OEM and aftermarket replacement options.
Use Our OEM Parts Lookup »Shop Outboard Parts by Engine System
Outboard engines use several interconnected systems. Select your manufacturer above to browse the exact categories available for your engine, including the following common repair and maintenance areas.
Common Outboard Problems and Where to Start
- Engine overheating: inspect the water pump, impeller, thermostat, pressure-control components, cooling passages, and engine anodes.
- Hard starting or rough idle: check fuel delivery, carburetor or injector operation, spark plugs, ignition components, filters, and intake sealing.
- Weak spark or no spark: test ignition coils, stators, switch boxes or ignition modules, sensors, wiring, grounds, and related electrical components.
- Low compression or poor power: inspect pistons, rings, cylinder condition, head and powerhead gaskets, bearings, and other internal engine components.
- Milky gear lube: inspect prop shaft, driveshaft, shift shaft, bearing carrier, and other lower unit seals for water intrusion.
- Lower unit or gearcase noise: inspect bearings, gears, clutch components, shafts, and gear lube condition before continued operation.
- Trim or steering problems: inspect hydraulic fluid level, seals, hoses, trim motors, pumps, steering cylinders, and mechanical connections.

OEM and Aftermarket Outboard Parts
OEM parts are supplied by the original engine manufacturer and are designed for the specific engine application. Aftermarket parts are replacement components produced by independent marine parts manufacturers and may provide additional availability or value for many common repairs.
Pro Marine carries both genuine OEM parts and quality aftermarket replacement parts for many outboard maintenance, repair, and rebuild applications. Always confirm fitment using the engine model, serial number, horsepower, year range, or OEM part number when available.
Frequently Asked Questions
How do I find the correct parts for my outboard motor?
Start by identifying the engine manufacturer, horsepower, model number, serial number, and year. Select the manufacturer above to browse by engine system, or use the OEM parts lookup to locate the original part number from a factory diagram.
Can I search Pro Marine by OEM part number?
Yes. If you already have the OEM part number, enter it into the Pro Marine site search to locate available OEM and aftermarket replacement options. If you do not know the part number, use the OEM parts lookup first.
What information should I have before ordering an outboard part?
Have the engine manufacturer, horsepower, model number, serial number, and year whenever possible. An OEM part number from the original component or parts diagram is especially helpful because visually similar parts may fit different engine families.
What is the difference between OEM and aftermarket outboard parts?
OEM parts come from the original engine manufacturer. Aftermarket parts are replacement components manufactured by other marine parts companies for compatible applications. Pro Marine carries both OEM and aftermarket options across many common outboard engine systems.
Are aftermarket outboard motor parts reliable?
Quality aftermarket marine parts are commonly used for maintenance, professional repair, and engine rebuilding. The best option depends on the application, manufacturer, availability, and customer preference.
Do you carry parts for older outboard motors?
Yes. Pro Marine carries parts for many older Mercury, Mariner, Johnson, Evinrude, Chrysler, Force, Yamaha, Honda, Suzuki, Nissan, and Tohatsu outboards. Availability varies by engine family and component.
What outboard parts are commonly replaced during routine maintenance?
Common maintenance items include engine oil, oil filters, fuel filters, spark plugs, water pump impellers, complete water pump kits, thermostats, gear lube, drain plug seals, anodes, and manufacturer-specific service kit components.
Fitment Tip: Outboard parts can vary by model, serial range, horsepower, and production year. Confirm the OEM part number or engine identification information whenever possible before ordering.

The same tensioner family is used on multiple Yamaha engine generations, ranging from select F200-F350 four-strokes to the later XF425 and XF450 XTO Offshore engines.
The timing belt itself is not the same for every engine family. Use the belt guide below to select the correct belt for your engine.
Yamaha used different timing-system configurations within similar horsepower ranges. Verify the complete Yamaha model number and confirm that your engine calls for one of the 6P2-11590 tensioner numbers listed above.
Choose the Correct Timing Belt
This tensioner fits several Yamaha engine families, but the correct timing belt depends on the engine. Pro Marine stocks both the F200-F250 belt and the later XF425 / XF450 XTO timing belt kit.
Yamaha F200-F250 Timing Belt - Sierra 18-15132 / 6P2-46241
Timing belt option for compatible F200, F225 and F250 applications using Yamaha 6P2-46241-00-00, 6P2-46241-01-00 or 6P2-46241-02-00.
Use this belt only on the compatible F200-F250 applications listed on the belt page.
Yamaha XF425 / XF450 XTO Timing Belt Kit - 6GR-W4624-00-00
Genuine Yamaha OEM timing belt kit for select XF425 and XF450 XTO Offshore applications.
This kit includes the timing belt and rotor bolts required for the applicable Yamaha XTO timing-system service.
Timing Belt Selection Guide
| Engine Family | Timing Belt Option |
|---|---|
| Select Yamaha F200 / F225 / F250 | Sierra 18-15132 / Yamaha 6P2-46241 Timing Belt |
| Yamaha XF425 / XF450 XTO | Yamaha 6GR-W4624-00-00 Timing Belt Kit with Rotor Bolts |
| F300 / F350 / Other Applications | Verify the correct timing belt using the complete Yamaha model number before ordering. Do not assume either belt above fits solely because this tensioner fits the engine. |
What the Timing Belt Tensioner Does
The timing belt tensioner maintains controlled tension on the engine's timing belt. Proper belt tension keeps the crankshaft and camshafts synchronized so the valves open and close at the correct point in the combustion cycle.
The tensioner must keep the belt controlled as engine speed changes. Excessive looseness, bearing wear or restricted tensioner movement can affect belt tracking and accelerate wear of the timing belt.
Common Signs of a Worn Timing Belt Tensioner
- Abnormal noise from the timing belt area
- Loose or inconsistent timing belt tension
- Tensioner pulley feels rough when rotated
- Bearing noise from the tensioner pulley
- Binding or restricted tensioner movement
- Excessive pulley play
- Timing belt tracking incorrectly
- Excessive belt vibration
- Unusual or accelerated timing belt wear
Why Inspect the Belt and Tensioner Together?
The timing belt and tensioner function as a system. A new timing belt can have a shortened service life if installed with a worn or binding tensioner, while a damaged belt should not be reused simply because the tensioner is being replaced.
Whenever the timing system is opened, inspect the belt, tensioner pulley, tensioner mechanism and related timing components before reassembly.
F200-F250 vs. XTO 425/450 Timing Systems
One reason this tensioner listing can be confusing is that the 6P2-11590-05-00 tensioner fits engines that do not all use the same timing belt.
Select F200-F250 engines use the 6P2-46241 timing belt family, while the XF425 and XF450 XTO applications use the 6GR-W4624-00-00 belt kit. Always match the belt to the exact engine model rather than matching it only to the tensioner.
