Sierra 18-5674 Outboard Starter - Replaces 5036972 - Fits Johnson, Suzuki 25HP 2006-11

The Sierra 18-5674 is an outboard starter engineered as a direct replacement for OEM number 5036972, built to restart Johnson and Suzuki 25HP outboards from the 2006-11 model years without modification. It is constructed of metal for durability in the marine environment and is designed to bolt into the factory mounting location so the ignition system cranks the engine the same way the original starter did.

This starter is a full-unit replacement rather than a repair kit, so buyers replacing a worn-out, seized, or intermittently failing starter can install it in place of the original part and return the outboard to service. It ships as a single, complete unit ready for installation, and its metal housing and internal components are sized to handle the electrical and mechanical loads of a 25HP outboard starting circuit.
