APE is known worldwide for our race prep on four-cylinder plain-bearing crankshafts. The who's who of racing depends on APE cranks for performance and dependability. Over 30 years of experience modifying cranks is available for your watercraft.
The advantage of a lightened crank... A much quicker throttle response and less power wasted trying to turn a heavy crank mean more power to the pump. The engine accelerates faster. Reshaped counterweights move through the oil mist with less drag.
ALL CRANKSHAFTS FROM APE ARE DYNAMICALLY RACE BALANCED TO LESS THAT 1/3 GRAM.
LIGHTENED AND BALANCED CRANKS
APE completely machines the crank counter-weights to remove weight and narrow the profile (sometimes called "knife-edging.") The oil holes are fluted on specific models to keep more oil at the bearings.
The crank is then balanced on a state-of-the-art computerized balancing machine to extremely tight tolerances.
