Rebuilding my gear case, and noticed my replacement Clutch Dog is a beefier design. Checked the MarineEngine website and didn’t notice any part  supersessions? Anything to be concerned about? Seems to fit the shaft and gears. I’m happy for the stronger design, but just don’t want to seal up the case half’s and have a problem.                                                    Does anyone know when, and if they changed the design, or was I sold the wrong Clutch Dog?                                                                                                                                                      Looking at the case, someone has already been inside (ie…double O rings on the shift rod rushing) possibly the original owner used the wrong part on his rebuild?                                       Thanks,                                                                                                                                                                                                                                                                                                                                Bob D
