On my '01 205V, its under the rear bench seat, then pull out the plastic compartment and its right there. I think it takes 6 screws to get it out, just don't do it with a full tank.

My 205v shows full until under 1/2 tank and then finally moves. This is due to the sending unit being at the transom end and the bow end of the tank being higher. Thought the gauge was stuck on full and only found out after running the boat for a few days. You can unplug the sender at the tank to check the gauge (should go to empty on the gauge when disconnected).

I have the same situation here. I have even replaced my sending unit. I tried to adjust it but failed (the while waiting thing is not for me) I just know roughly how much I have and never go under 1/4 tank. If I want to know where it is then I open my cover where the drain plug is and look at the tank. I cleaned it well enough to see it. Bought the new sender for $30 if I recall correctly.

It is a metal tube and it does not have a float in it. Someone else can elaborate because I do not know how it works exactly.

By the way, I also have a 2000 Maristar.

205v same issue. Anything you can do or just make sure not to go under 1/2 tank? Been filling tank when needle is at just above 1/2.

I have the same issue with my 99 205v. It stays pegged on full. Goes to empty when I turn the key off. I ordered a new sending unit from great lakes skipper via eBay today. It cost 34.99 shipped. Hope it does the trick.
