I only have 21 hours on the 400 so far but no issues. It has performed great. I have Wakesurfed full ballast and 5 adults in the boat. I have Wakeboarded 50% ballast and 4 adults.

I am in South Carolina at only a couple hundred feet of elevation. Salesman told me the 400 would work for me as well. Said I would only really need the 450 if I was wakeboarding 100% ballast and a boat full of people. So, I went with the 400 and I’ve been happy so far.

Message me if you have any specific questions.
