  • Pistons are T-6 Heat Treated

Crossflow: The oldest design, and the one used on Mercury / Mariner /Force 35-150 HP engines from 1970-1990 is the crossflow piston. As the air / fuel mixture travels through the transfer port and into the cylinder, a deflector, cast into the top of the piston, directs the air / fuel mixture towards the combustion chamber and spark plug tip for maximum efficiency. All engines with deflectors on top of the pistons will be crossflow engines. External inspection of a crossflow engine will reveal removeable transfer port covers on the side of the cylinders.

    GLM’S EXCLUSIVE MARINE PISTONS
  • Fully Machined Hypereutectic Pistons
  • Featuring a Hard Anodizing Coating on Top
  • Resisting Temperatures up to 1560°F
  • Hardness: HV280-400
  • Pistons are T-6 Heat Treated

Loopcharged: In 1976 Mercury / Mariner /Force introduced a V6 engine with loopcharged pistons. This engine was the V-175 HP 6-Cylinder. A loopcharged engine has a transfer port cast into the cylinder wall in such a way that it will direct the air / fuel mixture towards the combustion chamber and spark plug tip without the need for a piston deflector. All engines with a flat top or a slight dome on the top of the pistons will be loopcharged. Loopcharged engines will not have removable transfer port covers on the side of the cylinders.
