3020PS Wiseco 1987-91 Standard 2-Ring Piston for Mercury 70 75 80 90 100 115 HP

Our pistons are cleaned, then soda blasted. This is why they have a flat gray look. Soda blasting leaves them spotless, dry, very rust resistant, and easy to pick out damage and defects. Soda is not the same as sand blasting, which leaves a pitted, rough finish. The gear is flat gray, but it’s a smooth finish with a slight sheen to it. When done this way, we’ve found that probably 1 out of 3 pistons are actually not in sellable condition. There is no way that we can sell you a piston covered in carbon and say with certainty that it’s in usable condition, so this takes the guesswork out of it.

Wiseco standard piston for Mercury motors in good condition. There are a couple of nicks here and there, but nothing that will affect the performance. This is the piston only, no rings or wrist pin.
