Reliability on the Water
Bridging the gap between overpriced OEM and unreliable aftermarket since 2005.
Who We Are
Founded in 2005, SeaSierra started as a small team of marine enthusiasts who were frustrated with the state of the marine parts market. On one side, there were OEM parts priced far beyond the value they delivered. On the other, there were cheap aftermarket parts that failed too often and too early.
We knew boat owners deserved better.
SeaSierra was created to bridge that gap – offering reliable, well-engineered marine components at fair prices, without the drama and guesswork that too often comes with buying parts for your engine.
How We Got Here
It started with a simple rule: if we wouldn’t run it on our own boat, we won’t put our name on it.
In the beginning, we focused on one simple but critical component: the water pump impeller.
Rather than chasing the lowest cost, we sourced high-grade materials and worked closely with dedicated engineers and manufacturing partners to make sure every impeller met strict performance and durability standards.
Word spread quickly. Boat owners across North America started choosing SeaSierra, not because of flashy branding, but because their engines ran cooler, their pumps lasted longer, and their boats stayed on the water instead of on the trailer. Their reviews, photos, and stories from the water became our real “advertising.”
That trust gave us the confidence to expand our catalog beyond impellers, while keeping the same core philosophy.
What We Stand For
Our core beliefs guide every part we engineer and sell.
Honest Quality
Parts should do what they’re supposed to do. No inflated promises, no hidden compromises.
Fair Pricing
Good marine parts shouldn't be unaffordable. We keep quality high and costs reasonable.
Real-World Reliability
We focus on the parts that matter most to keeping you on the water—cooling, fuel, and wear parts.
Customer-Driven
Feedback from boat owners and mechanics isn't "nice-to-have"—it's how our product line evolves.
Made Together With Our Customers
SeaSierra didn’t grow because of a big marketing campaign. It grew because customers took a chance on us, installed our parts, and then came back with their stories.
Each engine that roared back to life, each successful repair, and each weekend saved on the water helped shape who we are today. SeaSierra is the result of thousands of decisions made by boat owners who wanted something better.
Looking Ahead
As we move forward, our goal remains the same as it was in 2005: to make it easier, safer, and more affordable to keep your boat running strong. Whether you’re maintaining a small outboard for weekend fishing trips or supporting a fleet of workboats, we want to be the parts partner you can rely on.
Thank you for being part of the SeaSierra journey.
