Exact fit and cheaper than a trip to a repair shop. Make sure you have the proper gasket sealer, a good scrapper that's not going to dig into the sealing surface, and tools for the job. I went on my computer and downloaded a video that walked me through the process. I'm a mechanic by trade but wanted to ensure everything was correct. I've been running the motor now for a couple of months. Peeing just as it's supposed to. No more delivering, waiting, and retrieving my boat from the shop for its routine service. Just follow your owner's manual to make sure you do all the necessary maintenance.
