Sea-Doo & Yamaha Performance

Real Experience. Real Parts. Real Results.

Calas Performance was built from years of hands-on Sea-Doo and Yamaha engine building, tuning, and racing in South Florida. Every part in the catalog and every kit recommendation is backed by that experience. This is not a generic parts store. When a part is listed for an RXP-X 325 or a GP1800R SVHO, it is because the build has been worked through in practice.

Our Story

Where Calas Performance Started

Calas Performance grew out of direct experience with PWC performance builds in South Florida. Founder Ernesto Calas spent years working on Sea-Doo and Yamaha engines before building a parts and kit resource around that knowledge. The goal was simple: give riders access to the right parts with the guidance to back it up.

Performance Parts

Built Around Real-World Experience

Every product and recommendation at Calas Performance is rooted in real-world testing, tuning, and time on the water. From Sea-Doo and Yamaha performance upgrades to reliability improvements and custom setups, our focus is helping riders choose the right parts for their specific platform, goals, and riding style.

Fitment First

Fitment Is Not an Afterthought

The vehicle database and Fitment Finder exist because wrong parts waste money and time. Every product is mapped to confirmed compatible models. The YMM selector, vehicle pages, and Help Center fitment articles are all built around the same goal: put the right part on the right ski the first time.

Frequently Asked Questions

What Riders Ask About Calas

No. Calas supports serious performance builds, but the catalog also helps customers find maintenance items, supporting components, and upgrade paths that match their watercraft.

Performance parts are not one-size-fits-all. Starting with year, make, and model helps reduce confusion and makes it easier to buy parts that belong on the machine.

Fitment-first means parts are organized around the watercraft they actually support. Calas helps customers shop by platform, model year, engine family, and upgrade goal so they can choose the right components with less guesswork.
