About Jeff Willoby

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. As Jeff got older, he began taking the thrill of speed to the next level. 

Jeff started getting involved in Super Stock 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 more out of his boats.  


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