We keep getting asked about this one — the nav light base is one of those Yamaha Marine 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
Light bases crack and the light works loose. The factory part is made from styrene-based plastic that loses its plasticisers over the years. It gets glassy, then one warm day it lets go under a load it used to handle easily.
How we reproduce them
Bring in the broken part and we'll reverse engineer it — usually with a design tweak that addresses why it failed in the first place, not just a copy of the weak original.
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.
