There is no way to, and no reason to, give the map to him.
When you have all five sections, put them together to reveal the 6th island, Skullduggery, located near the Pirate Outpost. Not only does it appear on the map, but you can now actually sail to it.
Once you chase Captain Crawfish away (in battle, with a big ship), the Governor will give you a bone shovel and the location of the Buried Treasure on Skullduggery. Go there and dig it up.
You have to beat Captain Crawfish before you can show the map to the Governor.
the crops on the skull that u give him
Once you have all 5 map pieces, the new island (Skullduggery) appears near the Pirate Outpost. But there is nothing you can do there until you acquire a Phoenix Warbird and defeat Captain Crawfish in battle. Once that is done, return to the governor in Fort Ridley and he will give you the map to the treasure on Skullduggery, and a shovel to dig it up.
He doesn't need to see the map. He knows where the treasure is buried. Once you recover the 5 map pieces, revealing the small island Skullduggery, you still have to earn enough doubloons to buy the Phoenix Warbird, and hire the Shipwright and Cannoneer. Only when you have defeated Captain Crawfish will the governor give you the directions to the buried treasure.
Joining the map pieces reveals a new small island named Skullduggery, just to the right of the Pirate Outpost. However, there is nothing to do there until you defeat Captain Crawfish. Once he is beaten, go back to the governor and he will give you the treasure location, and you can go to Skullduggery to dig it up.
Once you have all five pieces of the Treasure Map, the 6th island, Skullduggery, appears on the map. When you acquire a powerful ship, and scare off Captain Crawfish, the Governor will give you the Treasure location and a bone shovel to dig it up. (see related question)
It is on the 6th outlying island (Skullduggery) which only appears when you have assembled the 5 pieces of the map. Once you have the map, and have defeated Captain Crawfish in battle, the Governor will give you the Treasure Location card and a bone shovel. Then you can dig up the treasure on the mysterious island.
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.
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.
well after you defeat Captain crawfish you enter skullduggery island. after finding nothing you head back to the main island and talk to the guy in the governor's house, he will give you a treasure map and shovel from there you go bak to skulduggery and meet captain crawfish to whom you defeat.
The 5 pieces of the treasure map reveal another small island (Skullduggery) where a secret treasure is buried. Once you get rid of Captain Crawfish, it will be safe for the villagers to recover it, and the Governor will send you to dig it up.
The small island (Skullduggery Island) appears once you have all of the map pieces, and view them together. However, you can't do anything there until you have beaten Captain Crawfish. Once you have, see the governor to get the location of the treasure. You can then travel to the island to dig it up.
