Let’s Dive into Sierra International 183042 Impeller
The Sierra International 183042 Impeller isn’t exactly the kind of gear that gets your adrenaline pumping like a new rifle or a high-speed winch, but trust me, when you’re miles from shore and your outboard starts overheating, it becomes the most important piece of kit on the boat. This impeller, designed by Sierra International for Yamaha outboard engines, is a critical component of your engine’s cooling system. It ensures that water is constantly pumped through the engine block, preventing catastrophic overheating and potentially saving you from a very long, expensive tow.
I remember a fishing trip on Lake Ontario years ago. The original impeller on my Yamaha gave out, and the engine started screaming bloody murder. I was fortunate enough to have a spare on board; otherwise, I would have been dead in the water. That experience taught me the importance of preventative maintenance and having reliable replacement parts like the Sierra International 183042 Impeller.
Upon receiving the Sierra International 183042 Impeller, I was immediately struck by its robust construction. It’s a small part, but it feels solid and well-made. The flexible rubber vanes appear durable and ready to withstand the harsh marine environment.
I considered a couple of other brands, including a direct Yamaha OEM replacement and a Mallory impeller. I ultimately chose the Sierra International 183042 Impeller because of Sierra International’s reputation for quality aftermarket parts and the comparable price point. I wanted a reliable alternative to the OEM part without paying the premium price.
My initial impression was positive. The impeller looked like a quality piece, and I was confident it would perform as advertised. It’s a crucial part that can make or break a day on the water.

I installed the Sierra International 183042 Impeller in my Yamaha 90HP outboard motor prior to a week-long fishing trip in the Florida Keys. The installation was straightforward, thanks to the readily available online tutorials and the impeller’s precise fit.

The engine temperature remained consistent and within the normal operating range throughout the trip, even during extended periods of high-speed running. The Sierra International 183042 Impeller performed flawlessly, providing consistent cooling and giving me peace of mind. There were no surprises or issues encountered during this first extended use.
Extended Use & Reliability
After several months of use, including numerous fishing trips in saltwater environments, the Sierra International 183042 Impeller continues to perform admirably. I regularly inspect the impeller during routine maintenance checks. There are no signs of excessive wear or degradation of the rubber vanes.
Maintenance involves a simple visual inspection for cracks or tears and flushing the cooling system with fresh water after each use. This preventative maintenance helps to prolong the life of the impeller.
