    I have these pistons in a Marine long block I got with the purchase of a boat. It is a standard rotation and I need a reverse rotation. So I'm in process of doing so is it true that I need to turn the pistons 180° because of the offset wrist pins?

    Asked by: Tj6063
    KB recommended this because the pins are .060 offset
