I decided to get fancy and ordered the CMC PT130 tilt trim unit to replace the factory tilt trim on a boat and motor I'm stripping and repairing. I can't figure out how to mount the motor to the CMC unit I must be missing something. Is the CMC unit compatible with this 1979 mercury I can't find any holes that line up at all. Or should I just stay with the original tilt trim unit and put a little money in to fixing it up and return the CMC unit. I have some pictures of how the motor was originally mounted.
