I can’t see broken mounts causing that either. I’ll bet you need to find a set of New Old Stock gears, AND a new clutch dog to go with it. All of these new parts need to go into the original gearcase that their made for….. otherwise, they may not work. I remember one time that I put together a Big Twin lower unit from parts and pieces. The gears were from a Gale and the rest was Johnson Evinrude…. it would jump out of Fwd. now and then, as the boat was coming up on plane. The gears themselves looked excellent to me. I replaced it all with a new old stock gear set, and clutch dog, to fix the problem. I wonder if your ”rebuilt lower units” all have the engagement lugs rounded off, along with the clutch dog? It doesn’t take much and they will let go. Have you tried disconnecting the control cable at the engine, and shifting it manually? We have some guys in the club that may have some New Old Stock parts available for your motor, in case your’e interested. I wouldn’t dump that 1K into those motor mounts either!
