That's a different story....
Alex, that paints a completly different story. If your only going to have it in the water a week or two at a time, then the only thing you should have to worry about is the battery. Just make sure it is either very reliable or new. If you look inside the boat, toward the back, you'll see a thru hull fitting, about 2 inches in diameter. That's a drain for the cockpit of the boat. I call these boats, "wet boats", because you can take on a big wave over the bow and it'll wash out the back through that hole. The other end passes through the engine compartment and out the back. You should inspect that hose to make sure it isn't dry rotted or cracked.
The other thing you need to check, is your bilge pump. With a hot battery, the bilge system has a water sensor that turns on your bilge pump automatically when water level covers the sensor for 10 seconds and will shut the pump off, after it's been dry for 30 seconds. You can test this by taking a piece of wire or a screwdriver and short it across the two poles, that face down. This sensor is near the pump and the wiring harness for the bilge pump, will also have the sensor wires coming out of it.
If you don't cover the bottom with anti-fouling and leave it in for a long time, you will have marine growth and you will eventually get blisters. The new boats are less prone for blisters because of a change in the marine fiberglass products..........:cheers:
