River Speed & Sport is Blythe’s inboard marine performance shop for people who don’t want

“good enough.”

We specialize in high-performance inboard boats — from routine maintenance and troubleshooting to full performance builds and upgrades.

Proven on the River. Proven in Competition.

River Speed & Sport is owned and operated by Parker Enduro winner Heath Hiebert — and that matters.

Because when your boat is pushing hard, the difference is in the details: proper setup, correct clearances, quality parts, and experienced tuning & engine building.

We build and service boats the same way we race them — reliable, strong, and dialed-in.
