128 Series – 2.5L Mercury Piston

In an effort to continue supporting the availability of parts for 2.5L 2-stroke engines, we have developed these piston to match Mercury OEM size, weight, but unlike our 127 Series, these come with Chromium Nitride rings that can be used in Nikasil or Cast Iron sleeves. Availability of parts from Mercury can be limited, so we offer these German manufactured 128 Series pistons as well as our USA manufactured 127 Series pistons to maximize the options available.

These are a favorite among F1, F2, and offshore racing teams!

FEATURES:

• This forged piston is factory finished to match OEM size and weight.
• Thermal barrier non-stick coating
