About Me

Erik Rosa

My name is Erik, I am a mechanical engineer based in Whitefish with experience maintaining, diagnosing, and repairing boats. I got my start at Malibu Boats as a powertrain engineering intern, where I worked hands on with prototype parts and helped maintain and upkeep a fleet of engineering boats, this experience gave me an understanding of how these boats are designed and built. I then spent two summers as a marine technician doing everything from routine maintenance to full diagnostics and major repairs on customer boats across the Flathead Valley. I hold a B.S. in Mechanical Engineering from Montana Tech and use the hands on experience and technical knowledge I've gained through work and school to maintain, diagnose, and repair your boat quickly to keep you on the water enjoying our great Montana summers.
