Evinrude Throttle Handle
by Thingiverse
Last crawled date: 6 years, 1 month ago
This is the handle mechanism for throttle control on Evinrude 9.9 outboard motor. This design was done in order to avoid high costs for the same cheap stock parts online. It turned out a bit bulky given the design requirement and desired strength, but it gets the job done.
Track: The most important part of this design which converts the radial force applied to the handle into linear force and motion applied to the throttle mechanism.
Caps: Caps for the top of the pin in order to not destroy the track and keep the pin tracking smoothly. Two parts are available with different diameter holes to account for printer tolerance variations.
Guide: Guide piece that goes around the pin and into the slot on the tiller. In order to keep the pin tracking vertically. Two parts are available with different diameter holes to account for printer tolerance variations.
Handle: The "sleeve" part of this is self-explanatory. Printed vertically with supports.
As far as the pin goes... I was fortunate enough to still have mine. However, I do not believe that a 3d printed pin would be a suitable replacement anyway and that is something that needs to be metal.
Material: My current model (the blue handle pictured) is print in ABS. That choice was made because of its UV and heat esistance as well as its reputation for overall strength. This being said, if I ever run into any issues with the current model, I will be reprinting in PETG. This is because it posses many of the same qualities I wanted out of ABS as well as a harder finish and a lower friction coefficient which would be more suitable for the sliding parts in this design. Long story short, I recommend PETG, however, ABS should be fine; just avoid PLA as this part will most likely see more abuse than PLA should, and will almost certainly be exposed to the sun.
