Product Details

The Sierra 18-15144 is a direct replacement timing belt designed for select Yamaha 4-stroke outboard engines. Engineered to meet or exceed original equipment specifications, this belt delivers the reliable valve timing performance and durability that today's marine engines demand. It is a direct interchange for Yamaha OEM part number 62Y-46241-00-00.

Key Features:

  • Meets or exceeds OEM specifications — engineered as a drop-in replacement for the original Yamaha timing belt
  • Nitrile construction for maximum durability and resistance to heat and temperature fluctuations
  • Chemical and contaminant resistance for long service life in harsh marine environments
  • Fiberglass tension member for excellent flex and elongation behavior under load
  • Positive slip-proof engagement ensures precise, consistent timing at all engine speeds

Cross Reference / Interchange:

  • Yamaha OEM: 62Y-46241-00-00
  • Sierra: 18-15144 / SIE 15144
  • Alt: 44-8108

Sierra timing belts are a trusted choice for marine technicians and boat owners performing routine maintenance or engine rebuilds. Replacing the timing belt at the recommended service interval helps prevent costly engine damage and keeps your outboard running at peak performance.

Pretty good so far

so far so good, thx

First time using Autoplicity. I will see how things go when my order reaches me.

Great and easy

I ordered a Thule 9002 Raceway Bike Carrier on Sunday, April 8 and received the product by Fedex on Wednesday, April 11 with just regular shipping. That is fast service. And the price was $43 cheaper than any other site on the internet (including shipping). I haven't had a chance to use the bike carrier yet but it appears to be new and as advertised with no issues as of this writing. I would definitely recommend this retailer for your next purchase. Order Number: 9111
