Lowering the motors would be my first move. It sounds like the props may be catching and slipping if they're mounted too high. A 4 blade prop with some cupping should help with that without lowering the mount since they get better bite in dirty water. Have you tried having the wedges removed? Depending on the transom setup you may not be able to trim down far enough which can cause it to porpoise. Have you contacted the manufacturer to ask about it? They may be able to help or point you to someone who can.Really shooting from the hip here but it may be worth removing any "ad ons" such as your bobs tabs and then working forward from a blank slate. Try adjusting one thing at a time and if it doesn't help then undo it and try something else. Dont be afraid to go back to something that didnt work if you get a marginal improvement with something else as the combination may fix it.
Is it possible to stuff a couple hundred pounds of weight in the front of the boat somewhere? Or move some of the weight that's in the stern to the bow... specifically the batteries?I did that. I moved both batteries from th back to the center console. No change.
