Lowe pontoons got water how to check where the leak is coming from?

[TigerSharkCrazy]

I've got 1989 Lowe 189 and the year I noticed that the leftside us lower than the rightside. I removed both rear drains and the left side had about 4 gal's for water. Is there a way to see where the water is entering?
