Product Details

The Sierra 18-2171 is a precision-engineered engine drive coupler designed for MerCruiser sterndrive applications. This critical drivetrain component serves as the connection between the engine's flywheel and the outdrive unit, transmitting power while accommodating slight misalignment during operation.

Key Features:

  • Direct replacement for MerCruiser OEM part number 55-1446
  • Manufactured to OEM specifications for reliable fit and performance
  • Durable construction designed to withstand high torque loads
  • Precision-machined splines ensure proper engagement
  • Essential component for sterndrive power transmission

This drive coupler is a wear item that should be inspected regularly and replaced if signs of wear, cracking, or damage are present. Proper installation is critical for safe operation and preventing damage to the engine or outdrive system.

I'M PRESUMING THAT THIS IS A BRAND NEW BATTERY AND NOT A REBUILT. SHOULD IT BE A REBUILD, PLEASE CANCEL MY ORDER. THANX, FRANK

Good price

I like that I could use my Amazon account.

Best price for the optima battery I needed for my boat, I will definitely add this site to my favorites.

I found Autoplicity on a well known online vendor and the experiance was excellent so now I just go straight to autoplicity.com directly my last order (17805) was for some parts for my very modifide Jeep and two things stood out, the price and shipping, both were top shelf and above my expectations. Now when I need parts I check autoplicity.com first. They are my #1 now.<br>

Good price

Bought an Autometer Ultra lite 2 pyrometer and it looks great. Autoplicity has the best prices on their products and ships their products very quickly. I will definetly buy from them again.
