The newer MERCURY props use the exchangeable hub system. One prop fits many engines, you just use the correct hub kit to fit it. I believe MERCURY started using it in 95 or 98. Most of MICHIGAN's props also use the new XHS system as well. Use the MERCURY hub kit's though, they come with all of the hardware you'll need to install the prop whereas MICVHIGAN only gives you the minimum to install it. And MERCURY has some really nice props out now.
