Troubleshooting & FAQ
How do I confirm this part fits my specific engine?
Compare the part number on your original component with the references in the Part Number Matrix, then verify the engine brand, model, horsepower, stroke, year, and serial-number range. If any of these details differ, contact a qualified marine parts specialist before ordering.
What are the signs of a failing tilt thrust rod?
Possible symptoms include failure of the outboard to remain locked in the tilted position, slipping from the locked position, excessive play, a bent rod, or visible corrosion or damage to the rod or spring.
Why are two Tohatsu part numbers listed?
The listed replacement references are 350-62121-2 and 369-62122-2. They are included as application references for this replacement assembly; verify the number on your original component and the complete engine identification before purchasing.
Is maintenance recommended?
Rinse the tilt mechanism with fresh water after saltwater use and inspect the rod, spring, clips, and surrounding mechanism during routine service. Lubricate only as specified in the engine service manual.
Can I install this part myself?
Installation may be suitable for someone with appropriate marine-mechanical experience. Because the tilt mechanism supports the outboard, use the correct service procedures and secure the engine properly. Professional installation is recommended if you are unsure.
Is this an OEM part?
This listing is for an aftermarket replacement, not a genuine OEM component. The referenced OEM numbers are provided for identification and compatibility comparison only.
What are the shipping and warranty terms?
Shipping options, delivery estimates, warranty coverage, and return conditions are determined by the current store policies and are shown at checkout or on the applicable policy pages.
