When you have assembled the treasure map, and driven off Captain Crawfish, see the Governor to get the treasure location and a bone shovel.
To get the bone shovel, you have to defeat Captain Crawfish. Return to Fort Ridley and the governor gives you the treasure directions, and a bone shovel to dig with. Go to the small island, Skullduggery, and follow the directions to the treasure.
There is nothing to be found on the hidden island (Skullduggery) until after you beat Captain Crawfish. After you defeat Captain Crawfish, the governor gives you a treasure location and a bone shovel. Sail to the hidden island. You will find the treasure under a mound, six paces right from the pirate flag.
Once you have defeated Captain Crawfish, the Governor will give you the location of the Buried Treasure, and a bone shovel to dig it up.
Rather than sinking, Captain Crawfish runs away when you beat him. That is enough for the governor. Go back to see him and he gives you the treasure location and the bone shovel.

You can't find the treasure until you have the location from the Governor at Fort Ridley. When you have beaten Captain Crawfish, and have all five pieces of the map, see the governor to get the location card and the Bone Shovel. Return to Skullduggery Island to dig up the treasure.
That is not the end of the quest. After Captain Crawfish runs away, sail to Fort Ridley and see the governor. He will give you a bone shovel and the location of the buried treasure. Sail to the hidden island (Skullduggery) and dig it up.
Once you defeat his ship, and have all five map pieces, return to Fort Ridley, where the Governor will give you a bone shovel and the location of the buried treasure. Sail to the new island, Skullduggery, and dig it up.
There is nothing to do on the small island, also called Skullduggery Island, until you have defeated Captain Crawfish. Once he is beaten, go back to the governor and get the map to the treasure, and a bone shovel. Return to the small island and follow the directions to find the buried treasure.
Although you can dock there (during a pirate attack), the island is only used at the end of the game, when you have defeated Captain Crawfish. The Governor will give you the treasure location and a bone shovel, and you can travel to Skullduggery to dig up Fort Ridley's buried treasure.
The Jolly Roger flag is on the top of the mast at the Pirate Outpost. The flag that marks the treasure is in the middle of the hidden island (Skullduggery).
