I've got a Max IV I use only for fishing. It's got the cheap Atwood pump and works just fine. I have spent the better part of the day in the water. When all the bearings are new I don't pump out hardly at all. Right now I know it needs bearings and I'm pumping out every 20 minutes. With a trolling motor on front it's a really handy boat and more comfortable to fish out of than a small boat as well.
