My Max 4 came with a bilge pump. Very familiar with pumps as I built/rebuilt industrial pumps that would move 25K gallons per hour. I will go to West Marine and install a larger pump with float switch. Also don't forget to install the drain plug, if any. More than one person has forgotten after draining the sump!Learn to fix it and properly tighten everything down, before going anywhere of consequence. They break down routinely. Bring a small tool kit and parts. Ensure you have a rope-a-long or something to extend the winch, or go with another argo for when it gets stuck. They do get stuck, and brutally as the bottom creates a "suck" that makes it extremely difficult to unstick. Say goodbye to your back. Don't cross fast water, find a slow pool or go up slow water. If you get sideways in fast water, even with an outboard, your gonna swamp and flip.
