Mercury Throttle Knob
A broken throttle knob shouldn't sideline otherwise good Mercury equipment, and with a decent sample to work from it usually doesn't have to. We've made this style of part before and can usually print yours without drama.

Why these break
Throttle and shift knobs split on the lever. The original was moulded thin to save cents at production volume. That was fine when the plastic was fresh — twenty years on, there's no margin left in it.
How we reproduce them
This is a quick job on our end — we take dimensions from your old part, adjust for print tolerances, and run a small batch so you have spares for next time.
We print these in ASA. ASA is the UV-stable cousin of ABS — it holds its colour and strength through years of Australian sun where the original plastic went chalky and brittle.
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.
