Product Details

The Quicksilver 8M0103774 is a genuine Mercury Marine OEM port side exhaust manifold engineered specifically for EC (Emission Compliant) catalytic V8 MerCruiser sterndrive and inboard engines. Designed for the 305, 350, and 377 CID (3.5L, 5.7L, and 6.2L) engine families on model year 2008 and newer applications, this manifold features a single catalyst design and is sold as a port side (left bank) unit only.

Key Features:

  • Port side only — designed exclusively for the left bank of V8 MerCruiser EC engines (order 8M0103773 for starboard side)
  • Single catalyst configuration — built for newer emission-compliant (EC) MerCruiser engine applications
  • Corrosion-resistant coatings — applied to internal coolant passages and exterior surfaces for extended service life
  • OEM specifications — produced to Mercury Marine factory tolerances for proper fit and optimal engine performance
  • Compatible engine families: GM V8 305, 350, and 377 CID MPI sterndrive and inboard engines, model year 2008 and newer
  • Supersedes legacy part number 879288A04

As a Quicksilver genuine factory part, the 8M0103774 ensures a direct-fit replacement with no modifications required. For a complete exhaust manifold and elbow kit covering both port and starboard sides, this manifold pairs with part number 8M0103773 (starboard). Always replace exhaust manifolds with a matching elbow assembly and fresh gaskets to maintain a leak-free system.

great so far

This item was priced very attractively and shipped promptly. It was ordered on Sunday,<br>June 10th and shipped the next day, arriving at my address on Tuesday, June 12th. A very<br>satisfacory buying experience for me.

Great experience.

Thanks Autoplicity you had the best prices I could find, fast shipping, and everything I ordered was exactly what I was looking for! Great Customer Service!

Nice site. Checked you folks against RockAuto and liked you way better!

Great Place to shop for Auto Parts Very Fast shipping

First off I gotta say that my item arrived much quicker than expected. Funny thing is I ordered a part from another site a few days before I ordered the one from Autoplicity... and I received the Autoplicity item before the other item. In fact the other item hasn't arrived it. Plus the one I ordered from Autoplicty is significantly larger. The item arrived in perfect condition. Pretty impressed. This company is on my recommendations list for sure. They even offer a small reimbursement for writing review. Sheesh they deserve it.

I placed the order on Monday, and the package was delivered two days later, on Wednesday...and that was with FREE SHIPPING!!! It was also at the best price I could find. What more can you ask?

Website was easy to navagate and found just what I needed. By far the best price online with low shipping rates. Shipment arrived just two days after ordering. Will be ordering from Autoplicity again in the near future. Very pleased, Thanks!

This is my second order, so far it's been a great experience.

Very good prices and incredibly fast shipping. Shipping costs were a bit high but I would definitely use them again!
