73 Seafari gas tank

[sokinwet]

My gas tank on my Seafari is located very far back towards the transom and I noticed that it is actually just touching the port side livewell. Does this sound like it has shifted to the rear? I thought it would be directly under the deck access panel. Just noticed this and haven't had the access panel off yet (sealed with 4200) Looks to me like the season is ending just in time!
