I Put a V8 Engine On My PaddleBoard

rctestflight・26 minutes read

A narrator dislikes the slow pace of paddle boarding and plans to attach a 10 lb V8 engine to make it faster, facing challenges like waves overwhelming the board. After creating a new clutch design and testing different propellers, the paddle board covers 3.2 miles in 2 hours during a race around Lake Union, showcasing minimal wear on parts like the bumpy bump clutch.

Insights

  • The narrator initially sought speed and excitement by attaching a V8 engine to a paddle board but encountered challenges due to the engine's weight, leading to the creation of a lighter V8 engine with a unique clutch system for propulsion.
  • Through meticulous testing and innovation, the narrator discovered that a toroidal propeller design outperformed traditional propellers, showcasing the importance of continuous experimentation and adaptation in achieving optimal performance in unconventional vehicles like a V8-powered paddle board.

"Bumpity Bump Clutch Improves Paddle Board Speed"

  • The speed of the paddle board was limited due to the clutch slipping, prompting the need for a new design.
  • A new clutch design using 3D printed parts with lobed teeth for power transfer was created to eliminate slipping.
  • The new clutch, named the "bumpity bump clutch," was tested and found to apply power gradually over 2 seconds.
  • Different propeller designs were tested, with the toroidal propeller surprisingly outperforming the traditional propellers.
  • A race around Lake Union was attempted between a petrochemical-powered paddle board and a solar-powered one.
  • The petrochemical-powered board had a toroidal propeller for speed, while the solar-powered one had a larger propeller.
  • During the race, the petrochemical-powered board experienced mechanical issues, including a burnt-out starter motor.
  • Despite the mechanical issues, the paddle board covered 3.2 miles in 2 hours, with parts like the bumpy bump clutch showing minimal wear.
  • Future plans include converting the St Drive Unit to Electric with full drive for further testing of the tootal propeller.
