COMP Cams Xtreme Marine camshafts take advantage of the newest developments in camshaft engineering. Their aggressive lobe design produces better throttle response and top-end horsepower than other cams with the same duration at .050 in., while delivering increased engine vacuum. These cams are available for everything from pleasure boats to race applications, so you can always enjoy Xtreme performance on the water. From hydraulic and mechanical, to flat and roller tappet, COMP Cams offers camshafts for your watercraft dating as far back as the 1950s.
