2005 Yamaha Two Stroke Service and Repair Manual

One code, 50TLRD, and one factory number, LIT-18616-02-65. Yamaha's coverage for this two stroke runs across the 2004 and 2005 model years, and the same material is listed in the general Outboard section.

Read the plate on the clamp bracket to confirm 50TLRD rather than a neighbouring 50 hp variant; the T, L and R positions describe configuration, shaft length and rotation, and they determine which specifications apply.

What the book covers

• Service specifications with wear limits
• Tightening torques at the step where they are needed
• Fuel system and ignition adjustment
• Powerhead and lower unit disassembly, including shim measurement
• Electrical tests with the readings Yamaha expects

Troubleshooting is organised from symptom to component, so a starting, idling or charging complaint has a defined path instead of a checklist of guesses.
