The service manuals all have diagrams. Get an OMC manual for 1987 and you will be all set.

yes, I know the manauls have them but I am doing a job for someone else & have no other need for the manuals since I have mercruisers, I was hoping someone would be kind enough to scan the diagrams & email them to me
