I have a 1996 Ranger 461 vs. I just recently had the following work done. New bilge pump, repairs to the livewells, power pole installation-installed on my jackplate. Here's the problem: My boat is now taking in water and I have no clue why. Took it out yesterday and within 3 hours or so noticed water rising from floor drain. Rear compartment was 2/3 full of water. Pumped it out but have no clue where water could be coming in. This is my first boat so my knowledge is very limited. Any help or suggestions would be greatly appreciated.
