Parts Desk Insight
The Alpha One is one of the most common sterndrives on the water ā and one of the most frequently under-protected. Replacing the full kit at haul-out is the right call: mixing old and new anodes creates uneven protection. Aluminum kits are now the go-to for boats operating in mixed or saltwater environments.
