Evinrude Seat Swivel Bush
We keep getting asked about this one — the seat swivel bush is one of those Evinrude parts that fails long before the rest of the unit is done. With your sample on the bench this is a realistic reproduction job.

Why these break
Swivel bushes wear and seats rock. UV exposure breaks down the polymer chains in the original material. By the time the surface looks chalky or faded, the strength underneath is already gone.
How we reproduce them
The process is simple: drop the part in or send clear photos with a ruler in frame, we confirm fit details, and print replacements — often with a little extra material where the original always cracked.
We print these in Nylon. Nylon is slippery and fatigue-resistant, which makes it the right choice for parts that pivot, slide or flex thousands of times.
As with everything in our library: whether a part can be reproduced depends on size, load, heat, material, and having a decent sample to work from. Send photos first — the assessment costs you nothing, and we'll tell you honestly if a genuine spare is the better option.
