If you have been around outboard racing for any length of time, you are probably aware of the name and reputation of the late Harry "Zak" Pasturczak (aka Pasturzak). Harry knew more about making Konigs go fast and his Zak-Konig race engines showed up in many of the outboard racing record books. Harry Zak was known for his expansion chambers, Zak intake and heads and other innovative ideas. Harry also, in his later years, contributed input and feedback to O. F. and Paul Christner on the R&D work of the Quincy Welding "Z" engines.

This photo is of a 1968 Konig VD 700cc 4-cylinder opposed 5-port outboard race engine with rare Zak intake and heads by Harry Pasturzak. It has a 14:15 ratio Konig gearcase.
