MERCURY
PISTONS
NOTES:
WISECO forged pistons are superior in strength due to the inherent nature of both the aluminuum alloy and the
forging extrusion manufacturing process.
WISECO makes more types of aftermarket pistons than any other brand.
WISECO has been manufacturing pistons for over 60 years.
The date of manufacture
(month, day and year) is
stamped on the upper
port side of the cylinder
block aft of the crank-
case split line.
