Cursed Pond

I fish this 5 acre pond quiet often its really shallow deepest part probably 7 feet its fool of underwater grasses everywhere i mean u can barely let the trolling motor down without gettin tangled up. Ive caught two ten pound bass outta there on topwater but the thing is i cant catch fish consistantly. You cant use crank baits too shallow and too weedy and ive tried all kinds of plastics including senkos but none seem to produce more than 1 or 2 fish. Any explanations or lure suggestions?
