How much extra weight can you put in a boat over the amount stated on the plaque and expect to float, get on plane, and turn. By the way I have an X2(X1).
Realistically, You'll be able to add 3-4klbs. After that you'll be running out of space to add additional weight and the time to plane will be wasting so much gas you'll realize it isn't worth it to go with a bigger wake.
I run 2200 lbs + in my SSV. I have no trouble getting on plane if everyone is sitting up front (I usually ride with no more than 3 + myself). If my boat guests are sitting in the back the boat is a pig to get on plane. However, with some guests sitting in back the wake is quite a bit nicer.
If you have perfect pass... and a wired remote to the throttle through your rope allt he way to your handle. You can do the following...
Un hook bilge pump... take boat plug out and let fill just far enough that water doesnt come over the side. That would be the most ballast I would recommend.
