One thing to watch out for is that if your Grampian has the OMC saildrive then the copper-based anti-fouling paints are not recommended because of the electrolysis. It does a number on the casing of the OMC saildrive which was notoriously bad.
I have the same issue - Nash 26 with a saildrive and need to remove the copper based antifouling that the previous owner used. I'll do that in the fall when the boat is hauled.
