What year is that motor? You said it was a 215 HP
Most Gray's that sported the flywheel aft carried a generator which hung under the exhaust manifold, on the starboard side of the eng. Gray didn't start putting altenators on eng's until 1963 with the flywheel foward amd the waterpump and altenator were on the top side of the eng. The altenator that was used back then was a Leece Neville. a very good altenator. If your replacing the generator I would recomend a Delco Marine altenator.with a built in regualtor.
I hoped this answered your question.
