Here is an easy test to see if it is your anchor lochor drain . Can be done on the trailer . Try this while the boat is somewhat dry , that way there is no doubt where the water came from .
The drain for the anchor locker is a shiny clamshell on the outside of the hull in the front of the bow on the side , usually the right side . Its supposed to be above the water line , some aren't . Find the clamshell and clog it or tape it up . It doe'snt have to be a water tight seal , we're not really looking for water to come out there . Ok , now you can either do this with the plug in or out . Plug in seems to be a bit more satisfying , the bilge pump should come on . Now take a hose and start filling up your anchor locker with water . Keep an eye on it , if your boat is like mine the wires for the trolling motor come out of a 2" hole at the top of the anchor locker . We don't want water getting through that hole , it would ruin the test . If you keep filling up the locker and the water is going somewhere into the bilge the bilge pump sould come . If all this happens you know what the problem is .
