If you're heading to the great outdoors, Comp Cams offers camshafts designed specifically for marine applications where low idle speeds are necessary and where restrictive exhausts require special cams that work well against wet exhaust system back pressure. These unique camshafts generate an extremely wide powerband, offering the low-end torque needed to jerk skiers up quickly and the high-end power needed for maximum performance. Also, Comp's larger camshafts are engineered for engines with less restrictive exhausts and drives that will tolerate higher idle speeds. An excellent choice for jet boats or power boats.

Features:
  • Extremely wide powerband helps get boat on plane while making maximum horsepower
  • Work against exhaust systems with restrictive back pressure
  • Power enhancement helps maintain top end speed for long distances
  • Intended for applications where low idle speeds are required

  • What distributor gear do you recommend for this cam

    Asked by: Bbc555
    It will depend on the distributor, but a brass or melonized gear should be used with the camshaft. If you are replacing a roller cam then the gear you have should work.
