What type of front motor mounts ? What are those mounts setting on ? Are u hand barring motor over or starter , with plugs out ? With this much trouble , finding problem. Heck bolt dial indicator to floor of boat. Turn over motor with starter and see if motor might be pulling front mounting bolts up and hanging. Just a thought.
Motor mounts new MC. Bravo inner plate is like new. Mounts are setting on solid glass/wood. Trust me. New transom. Plugs out when turning over. Magnetic stand for dial indicator. Problem is in coupler. I ordered new one! THX!!!!
