I have an 08 LSV as well, and ya you need more weight! We have about 1000lbs on either side of the engine, stock 400lbs bag in the floor/front and a 850lbs bag in the bow. Usually only a driver and spotter in the boat. When wakeboarding we have the wakeplate up all the way and if we ever surf (hardly ever) we put the plate down all the way to make it steeper. So I think you'll have to get your plate fixed. For wakeboarding, I think it needs lots of weight up front. A little too rear heavy and the wake gets too steep and rolls over. It's like hitting a curb. Too much bow weight is better than too much rear weight in my opinion because if it's a little too flat I can easily drop the wakeplate down a hair to steepen it up but that basically never happens. Mid ship weight is the safest. So when extra people come in we keep them as centered as possible (out of the back bench and out of the bow if possible) Even just slidding the back bench forward helps. We do not have an upgraded prop, which is crappy because it takes us a while to get on plane for wakeboarding. We've pretty much maxed out the weight capacity at this point I think - when we have a bunch of people on the boat we sometimes have to dump some weight or it won't get up on plane. So maybe I should be investing in a new prop!

One other thing - deep water helps as well. We ride in a river that's pretty shallow, like 10 feet. We like it in there because it's always calm, but when going into deeper water like out on the lake, the wake does get a little bigger and fuller. In fact, we can't ever surf at all in the river - the wave just doesn't form right. We only wakeboard though and we're willing to sacrifice a hair of volume on our wake for nice water but if I was surfing I would need to be in deeper water.
