Good morning to all. I have a 1989 mercruiser engine 3.0. I bought a shift plate replacement (864363a). Can’t seem to align it up and be able to mount it. Does anyone have any pics or installation guide. The only thing that came with it was a parts list and not so good instructions. I don’t see a way to really mount it. Have to keep in mind I have the hole that can’t be covered up because of the hose coming off the spark arrestor. Thanks in a advance for any info
