Re: bilge pump setup
brand really doesn't matter.
Does your boat have drains at the stern, going through the transom, so that if you get water in the boat, it washes out the back? And if it rains, does it run out those holes (the holes are higher than the water line)? that's one form of self-bailing.
Another is a boat that while moored, you can pull the plug and it won't fill with water. Rain water will drain out. But when you get in the boat to use it, it starts filling up. Boston Whaler and Carolina Skiff do this--but it depends on motor size (weight) too.
Or do you have a floor drain, and water that gets in your boat drains down under the deck, and has to be pumped out or run out?
I started to say, I sure hope your boat came with a bilge pump. But that's making assumptions. Many smaller open boats don't have them; you just bail them out or run them out. Many small boats don't have batteries, so no pump. I made a float switch bilge pump for my whaler out of a D-cell pump b/c I didn't want to add a boat battery (pull-start motor) but I sitting low and getting some slime from the small amount of water in the stern.
what is your boat?
