Thanks to all for making this a great resource for us newbies! I have recently acquired a 1962 1700 Hydrodyne Deluxe with a Volvo AQ100 Outdrive System. I am continuing restoration started by the previous owner, but need help in understanding what appears to be a tilt or trim system designated as a Morse Control System type M1. Does anyone out there know how this operates, how to trouble shoot and how to set it up and bleed the system? It operates from a single handled pump with a single hydraulic line attached to the steering tube cylinder. Thanks in advance for any information you can provide.
