Product Details

The Sierra 18-2746 is a premium replacement exhaust manifold boot designed for MerCruiser stern drive engines. This critical component creates a flexible, watertight seal between the exhaust manifold and the exhaust elbow, allowing for thermal expansion while preventing exhaust gases and water from entering the bilge.

Key Features:

  • Direct replacement for MerCruiser part number 55-1525
  • Constructed from durable marine-grade rubber compound for resistance to heat, salt water, and exhaust gases
  • Accordion-style bellows design accommodates engine movement and thermal expansion
  • Essential component for maintaining proper exhaust system integrity
  • Meets or exceeds OEM specifications for fit and performance

Regular inspection and replacement of exhaust boots is critical for preventing water intrusion and exhaust leaks. This Sierra replacement part provides reliable, long-lasting performance at a competitive price point compared to OEM parts.

Great site ease of use and greaT PRICING - THANK YOU

beat price on the part i was looking for

very good

Seller had the best price online for the item I wanted! Responded to emails within 24 hours as stated, and sent me my tracking info as soon as part shipped. Thanks Autoplicity!

I found exactly what I was looking for and it was listed for a very awesome price! Matter of fact it was lower than any other store I had found that part on. Shipping was super quick and I will totally shop from Autoplicity again!

Thanks Eddie! Love you long time!

Ordered A K&N Filter For My Bike. The Price Was The Cheapest On The Web. It Shipped Right Away. Very Happy

Great so far

If it fits I will be very happy.

I can't believe how much money I saved buying from Autoplicity. I had been shopping the Bakflip for months and this price easily beat every other online store for the same exact item. My item shipped direct from the factory within days. I couldn't be happier.

Communication was acceptable and shipping times within initial promise. Would and will buy from them again...

No probs
