Spark plugs on 3100 open
#2
On our 1988 31 Open, I would unbolt the forward hinges,  raise the hatch and place a 4X4 across the opening. Then lower the hatch on the 4X4, disconnect the ram and slide the hatch aft on 2X4's laid on the deck. On the port side the cabin door must be open to make room for the raised center hatch.
A padded swim mat would go on top of the engine to provide a comfortable place to lay on.
Not a fun job but do=able. 
The head is cast iron so it's not easy to cross the spark plug threads. Just run them in finger tight and then snug them with a rubber lined spark plug socket.
If the fuel filter, oil filter and water pump are buried outboard, i suggest you do them at the same time.
