This timing belt is engineered to meet or exceed OEM specifications, providing a reliable replacement for specific Yamaha 4-stroke outboard motors from 25 HP to 40 HP. It is essential for maintaining correct engine timing and preventing catastrophic engine failure if the original belt is worn or damaged.

  • Direct-Fit Installation: Designed as a direct replacement for the original OEM belt, ensuring a precise fit without modifications.
  • Durable Construction: Made from high-strength rubber and composite materials to withstand the harsh conditions of the marine environment, including heat, oil, and abrasion.
  • Critical Maintenance Part: A crucial component for your engine's health, responsible for synchronizing the rotation of the crankshaft and the camshafts.

Installation Guide

Professional installation is highly recommended. The following are general steps for reference:

  1. Safety First: Disconnect the battery and ensure the engine is cool.
  2. Access the Belt: Remove the engine cowling and any flywheel covers or components obstructing access to the timing belt.
  3. Align Timing Marks: Carefully rotate the crankshaft by hand until the timing marks on the crankshaft and camshaft sprockets are perfectly aligned with the marks on the engine block.
  4. Release Tension: Loosen the timing belt tensioner bolt to release pressure on the belt.
  5. Remove Old Belt: Carefully slide the old timing belt off the sprockets.
  6. Install New Belt: Install the new belt, ensuring it is properly seated on all sprockets and that the timing marks have not moved.
  7. Set Tension: Tighten the tensioner to the manufacturer's specified torque to apply the correct tension to the new belt.
  8. Verify Alignment: Rotate the crankshaft two full revolutions by hand and re-verify that all timing marks are perfectly aligned.
  9. Reassemble: Reinstall all covers and components in the reverse order of removal.
  10. Test: Reconnect the battery and start the engine to ensure it runs smoothly.

Troubleshooting & FAQ

How do I confirm this timing belt fits my Yamaha engine?
First, check your engine's model and year against the "Compatible Engine Models" table on this page. This belt fits Yamaha F25 (1998–2006), T25 (1998–2006), F30 (all years), and F40 (2000–2008) models. Second, confirm your engine's original part number is 65W-46241-00-00 or one of the listed cross-reference numbers.

How often should I replace my outboard's timing belt?
Replacement intervals are set by the engine manufacturer, but a general rule is every 5 years or 1000 operating hours, whichever occurs first. Please consult your Yamaha service manual for the precise maintenance schedule for your outboard model, as neglecting this can lead to severe engine damage.

What are the common signs of a failing timing belt?
Symptoms of a worn or failing timing belt can include a ticking or slapping noise from the engine during operation, difficulty starting the engine, rough idling, or a noticeable loss of power. A visual inspection may also reveal cracks, fraying, glazing, or missing teeth on the belt. If you notice any of these signs, replace the belt immediately.
