1. A water level indicator for a pontoon tank comprising:
a float mechanism that comprises:
a support mechanism that does not move; wherein the support mechanism is fixedly attached to a manway cover that protects the pontoon tank;
an extension system with an extension rod adjustment system that contacts the support mechanism at a first end and that contacts a float at a second end that is opposed to the first end; and
a movable portion that comprises a plurality of levers; wherein the movable portion contacts the support mechanism and the extension system; and wherein the plurality of levers act cooperatively to displace a gauge rod in proportion to a fluid level in the tank; wherein the support mechanism comprises a first vertical beam and a second vertical beam, where the first vertical beam is longer than the second vertical beam; a horizontal beam in contact with each of the two vertical beams, a first inclined beam that contacts the first vertical beam; and a second inclined beam that contacts the first inclined beam at a distance between ⅓ (one-third) and ½ (one-half) of the distance as measured from the first inclined beams point of contact with the first vertical beam.
