DC/AC grounding

Hello folks. I have recently acquired a sailboat with an outboard motor and plan to rewire her this spring. I have rewired a few of my previous boats that had inboard engines which makes the single ground point obvious. However, since my outboard is raised out of the water when not in use then where is the common ground point?

If I connect the AC ground to the DC ground (per ABYC) on the engine then it doesn't seem it would work if the engine was raised out of the water. Do I need to install a separate grounding plate on the outside of the hull to use as the single grounding point instead?

Thanks!
