  • New Mercury 40 inch pistons

    I have been working with Wiseco on a Mercury 40 cubic inch piston. I am paying for new dies and will have them in Standard, plus .020 and .040 inches oversize. My initial run will be for 50 pistons. Next run I can add .015" and .030" oversize as well if folks want them. They will be to the latest Wiseco design, improved two ring configuration and there normal coatings. I am hoping that we can sell them for $130 with rings, pins and clips. Deposit has been sent so I expect to have them in hand in 6 to 8 weeks. Let me know if you would like some in that the first run will be 50 pistons or so. Pistons are impossible to find for the D Merc so I am hoping this will help with keeping the engine in service.

    Note: They also fit 20 and 60 cubic inch engines.
