How are you getting 1,000 in the back locker and 600 center?
I've got an '04 Lightning an older and different hull than an ’06 Elite. The built in center tank in my boat is 230 pounds and the built in v-drive locker hard tanks are 180 pounds.
I run a 750 on top of the 180 in the V-drive locker, and a 750 on the bench or behind the driver's seat. I have 270 pounds of bag weight that I put in the bow. I also put 80 pounds of bar bell weight on the tower. Not counting people I'm running as much as 2,200 ponds of ballast.
I’ve changed the pitch of my prop from 12 to 10.5 inches to reduce the load on the drive train.
If your wake is short and your surfing near the pocket try speeding up or moving weight forward.
I get a pretty good regular wake but my goofy wake does not measure up to the regular wake. We run the hydraulic trim tab up for regular surf and down for goofy surf wake.
