Madman Engineering - a small high performance shop specializing in modifications for all small engines.  Every cylinder, crankshaft or engine we build we treat as our own.


(We do not cut corners or rush work, period.  It is a waste of our time and your money.) 


I, Martin Marino, have over 37 years experience modifying engines.  Many of these engines and cylinders have won national events in road racing, motocross, flat track, motorcycle ATV drags, ATV hill climbs and Jet Ski Watercraft racing.

I have worked and played with some of the best two stroke engineers in the world.  In 1983 Paul Gast and myself assembled the first Kawasaki Jet Ski to exceed 50 MPH (550 single carburetor piston port engine. 

I assisted in the design and manufacturing of 440 and 550 Kawasaki Jet Ski cylinders that were distributed by Orange County Jet Ski and later Performance Jet Ski .  I have worked with Kawasaki Watercraft, Aprilia Racing,  Performance Jet Ski, Butch's Jet Ski Shop, Paul Turner,  Artic Cat Snowmobile team,  Lumbert Marine The list is endless.
