| OMC PISTONS 65 HP - 115 HP |
Wiseco
forged pistons are superior in strength due to the inherent nature of both the
aluminum alloy and the forging extrusion manufacturing
process. |
| A PRO PISTON is made of the
highest quality alloys. Pro Pistons are made from high silicon aluminum alloy and meets or
exceeds oem specifications. The Pro pistons are our most economical
piston line. |
| The Pro-V PISTON is made of the
same alloys as the pro piston adding a grey moly coating. Moly reduces friction during the
critical break-in period and helps dissipate heat as well. |
*All pistons are sold with wrist pins, rings, and
clips (unless noted).
**All piston kits include one piston only. |
