Evinrude Throttle Handle

thingiverse

This mechanism handles throttle control on Evinrude 9.9 outboard motors, engineered to avoid costly stock parts online by creating an affordable alternative. It's not the most elegant design, given its bulkiness, but it effectively gets the job done. The main function of this track is to convert radial force applied through the handle into linear force and motion that controls the throttle mechanism. These caps protect the top of the pin from damage and ensure smooth tracking by preventing wear on the track. Two sizes are available, accommodating printer tolerance variations. This guide piece fits around the pin and into a slot on the tiller, keeping it aligned vertically. Two versions are printed with different diameter holes to account for varying printer tolerances. The handle itself is straightforward; it's a self-contained unit that prints without supports. Replacing the pin with a 3D-printed one isn't recommended due to its intended metal composition. ABS was chosen as the print material because of its UV and heat resistance, along with its reputation for overall strength. However, if issues arise with the current model, it will be reprinted in PETG. This is because PETG possesses qualities similar to ABS, including a harder finish and lower friction coefficient, making it more suitable for sliding parts. In summary, while ABS should suffice, PETG is recommended due to its superior durability and performance.
