Standard Bore Cylinder Kit

  • Same reliability and performance of the original components
  • Maximum durability and smoothness guaranteed by a special nickel and silicon treatment
  • Gaskets developed with the most advanced technologies to ensure maximum tightness even at high temperatures and pressures

Athena has been constantly investing in cylinder aftermarket replacement parts for more than ten years, to improve their production and performance.

All the cylinders are entirely engineered in Italy by Athena’s R&D Department which has a strong internal know-how and cutting-edge tools to design and test each piece. They are coated with motor-nicksil, a nickel-silicon coating developed by Athena to obtain smoothness and optimal wear resistance.

Athena’s cylinder kits and its components are recognized worldwide for their performance, durability and reliability.

The Standard Bore cylinder kit developed by Athena guarantees the same performance as the original spare parts, extreme reliability and optimal smoothness as a result of the lightweight aluminum cylinder, the barrel with nickel-silicon coating, and a piston designed to reduce further friction.

The kit includes the high-quality aluminum cylinder with standard bore, the complete piston with the piston pin and rings, and all the necessary gaskets.

All the components of the kit have been developed to withstand the highest temperatures, pressures and stresses and have been validated by Athena technicians with severe bench and road tests.

This cylinder kit can be installed without making any changes to the engine crankcase.

Direct replacement on my 95 SeaRay 175
Size: PP67-712 V1
My boat started to have issues with not turning over when I used the ignition switch. Replaced the switch and had no effect. Replaced the solenoid and that fixed the problem. Good price, so I replaced all 3 solenoids (Trim/ starter). Solenoids had all needed hardware (nuts/washers)
