Jeff Willoby’s passion for Boats & Racing started when he was younger.  Jeff’s father owned a boat shop named Lake Shore Marine. His father would keep him busy Sweeping floors, cleaning boats and even doing oil changes. He has been around boats all his life. He attended his first Boat race when he was only two years old! As Jeff got older, he began taking the thrill of boating to the next level.


Jeff started getting involved in Super Stock Boats and Cracker Box Racing.  At age 15 he was the Driver behind the wheel.  Not only did he display his skills on the water, but his inventive methods pushed him to always get the most out his boats.  He takes great consideration to the details that most commonly overlook.   

With all Jeff’s experience and years of building motors, as he got older, his reputation grew for making fast boats.  Today, Jeff makes the possible happen with an array of customers boats and his hobby Race Boats.
