Hello, I have a 1990 force 150 outboard motor. I am rebuilding it myself. I put the pistons in and bolted the head back together. After I bolted the power head back to the motor leg, I realized the three pistons I replaced are not the same diameter. Will they still work? The pistons appears to be about 1/8" in diameter smaller than the stock pistons. The rings seem to be against the cylyinder walls but I fear the rings may break because the are not compressed far enough. This is my first rebuild and I trusted they were the right size when I purchased them. I didn't think to size them up. A boat shop peressed the rods on them. Thanks
