It suits boats fitted with Whirl Away or Ski Race style releases. Part numbers covered are AM1058 and AM1058WA. Choose the option that matches your installed release, then confirm during installation for best results.

Specifications and Materials
This listing supplies the spring only. Dimensions and material can vary by release style, therefore select the correct variant at checkout. Additionally, inspect the hub, dogs and bearings while the assembly is open. Replacing a fatigued spring often improves engagement feel and reduces nuisance slip.
Compatibility and Fitment
Two options appear in the selector:
-
Circuit Race Whirl Away for ratchet or free-wheeling systems used on circuit boats.
-
Ski Race Prop Release for ski-race configurations that share the same release concept.
Before buying, verify your gearbox model and visually match the existing spring. If uncertain, compare coil count and end shape to your current part. The Prop Release Spring name is used consistently so you can align it with workshop notes.
Compliance and Safety
Australian racing rules expect a ratchet or free-wheeling release to limit deceleration if the driveline locks. For a concise overview relevant to NSW events, see: https://www.nswapba.net.au/rules.html
Marine Applications
Use cases include inboard ski race and circuit boats where a release is fitted to an Argo V-Drive. Consequently, replacing a weak spring supports predictable pit manoeuvres and safer behaviour under load. Moreover, routine spring renewal is a low-cost preventative step during gearbox service.
