Yanmar
Some 3D designs for the Yanmar engines and saildrives, like ignition key and stop knob, and shim for the saildrive.
Ignition Key
The metal ignition keys from my 3JH3E engines were corroded and were always reacting with the metal of the lock, regularly binding. I always keep the key in the ignition so that sailors can rescue my boat in case it starts dragging its anchor, so there is plenty of time to corrode.
I printed a new set of keys from PAHT-CF. This is carbon reinforced nylon. I tried printing first with ASA but that turned out to be too weak.
Be careful here: If the key breaks at an unfortunate moment loss of property or life can occur!
Stop knob
My engine installation has the mechanical stop knobs that operate via a bowden cable. The T-handles were looking ugly and always mis aligned. I designed nice round knobs that also cover the (often rusty) nut underneath. I printed them with ASA because they are always outside in rain, spray, and strong UV. To attach them, it might help if you use a thread cutter first, then use a grip spanner to prevent the stud from turning.
SD50 saildrive shim
The prop shaft seals of my saildrives started to wear out more quickly. Problem is that the seals worn a groove in the prop shaft, which is a common problem. If you put this shim in the seal housing first, the seals will shift up a little and start working on a new part of the shaft. This is a much easier and cheaper solution than buying a new shaft, using a sleeve, or have the shafts welded up and machined afterwards. I printed these with PETG, which is oil and water resistant. Once installed, there is no force acting on them so they are strong enough.
