Got a new 16 ft princecraft boat with side drive, subfloor, 40 hp 4 stroke yamaha engine two weeks ago. First, the bilge pump on it stopped working. Followed by constant blown fuses for the livewell pump. the boat would take on an unusually large amount of water in a short time and I couldn't figure out where it was coming from till I pulled it out of the water last night. I had taped off the water output fitting on the outside of the boat to see if that was where the water was coming in. The boat was half filled with water in only an hour. When I pulled out full of water last night, I left the water drain plug in to determine where the water was leaking in. It took only a matter of seconds to discover a hole the size of a small drill bit on the underside of the boat just behind the driver's seat. There is a bit of a metal burr surrounding the hole facing outward which leads me to think that whoever installed the subfloor at the factory screwed up and drilled right through the bottom of the boat.
