I've solved the problem but the question relates to the lifting tool referred to in the service manual in the section on "Lifting Information", where it states, "Install OMC Lifting Tool, P/N 342672, on crankshaft. Tighten mounting screw securely using......" etc. The picture showed a threaded pin that screws into place with a swivel lift point on the exposed end. Online they are priced high for one time use I thought, so wanted to make my own. However, when I took a second look at my outboards they had suitable lifting eyes already in place and I was able to lift them without problems. But thanks very much for your reply.
