is my stringer hydro-mechanical or mechanical

The boat is a 1980 seaswirl. What type of shift is it? I had always thought it was a mechanical. What are the main differences?

Should be a hydro-mechanical. It uses a pump in the outdrive to assist in shifting. It also does not use a shift interupt switch (mounted on the shift converter) to cut ignition during shifting. It is, in a sense, a mechanical shifting unit. It is just hydraulically assisted.

Mine does have to be in neutral to start motor is that the same as a shift interupt switch?

The switch you have is built into the shifter to prevent starting in gear. All boats have one. The interrupt switch is a switch that attaches to shift control box on top or rather at the back of the engine, it sends a signal to the ESA (electronic shift assist) module when you go in or out of gear. The ESA will cut out a few cylinders stumbling the engine as you go in or out of gear. It's only for a few seconds and drops torque and allows the drive to slide in or out of gear easier and also helps with wear and tear.
