For DIY outboard mechanics, restoration specialists, and boat owners, keeping a classic high-thrust mid-range outboard motor running like factory requires exact structural components. When saltwater scale builds up, water jackets corrode through, or bracket components suffer stress fatigue from thousands of miles on the trailer, hunting down proper OEM parts can stall your rebuild project for weeks.

At DobsonParts.com, we specialize in high-demand, structurally sound components meticulously stripped, cleaned, and verified for exact structural compliance. This week, we have logged a pristine teardown selection targeting the legendary 2003 Yamaha 50 HP High-Thrust (T50TLRB) four-stroke setup. Below is an engineering and part-number breakdown of the top inventory assets currently available for immediate dispatch.

Essential T50TLRB Factory Components Now In Stock

When managing repairs on mid-range Yamaha four-stroke marine blocks, substitution is not an option. Gaskets must align with deck pressure parameters, and structural casings must withstand full hydrodynamic torque forces. Here are the exact factory components waiting on our shelves:

  • Yamaha Outboard 50 / 60 HP 4-Stroke Outer Exhaust Cover (Water Jacket)
    • OEM Part Number: 62Y-41113-20-1S
  • Yamaha 40HP / 50HP Four-Stroke Aluminum Oil Pan Assembly
    • OEM Part Number: 62Y-15311-02-5B
  • Yamaha 2001–2004 Upper Casing / Midsection Exhaust Housing
    • OEM Part Number: 62Y-45111-21-4D
  • Yamaha 50HP Left & Right Clamp / Stern Transom Bracket Assembly
    • OEM SKU Set: 62Y-43112-00-4D (Port Side) + 62Y-43111-00-4D (Starboard Side)
  • Yamaha Outboard 2002–2004 Top Engine Cowling Hood Assembly
    • OEM Part Number: 64J-42610-10-4D

Why Settle for Third-Party Alternates?

Aftermarket structural marine components often suffer from minor casting variances, throwing off upper-to-lower unit alignment and placing excessive side-load friction on your driveshaft. Buying authentic, inspected Yamaha salvage and overstock guarantees that wall thicknesses, alloy compositions, and anti-corrosive paint coatings match the exact specifications set by the original factory engineers.

Zero-Friction Technical Discovery via Part Number Match

At DobsonParts.com, we strip away the guesswork. Every listed component is tagged explicitly by its exact engineering cast marker or OEM part number suffix. If your technical schematic lists it, our inventory indexing guarantees an exact drop-in structural match.
