Reliable engine starting is the foundation of safety and comfort on the water. For MERCRUISER units, using original or high-quality replacements like the Starter Bolt SIERRA 18-8404-1 is crucial. This precision-engineered part is dedicated to 3.0 liter engines produced between 1987-1994. Thanks to its exact geometric fit, it ensures stable mounting and proper operation of the starting mechanism, leading to faster and more secure engine starts. Choosing a part from the renowned SIERRA manufacturer guarantees durability and resistance to harsh marine conditions.

Installation and Operation

When replacing the starter bolt, we recommend thoroughly cleaning the mounting hole of corrosion and debris. Ensure the threads are intact and tighten the new bolt to the specified torque to prevent loosening during engine operation. Regular inspection of fastening elements before the sailing season will avoid unpleasant surprises during your trip. Remember that a properly installed 18-8404-1 bolt not only secures the starter but also minimizes vibration risks, extending the lifespan of the entire drive system.
