[QUOTE="Fish Taco, post: 101202, member: 1850"] I'm not a fan of trim tabs or of anti-ventilation plate additions. I'm not saying they can't be useful, but they are unnecessary in most cases. When you trim your motor out, you're reducing the drag of the lower unit in the water. When you start to porpoise, you're forcing the bow up and down because of trimming the motor out too much. I agree with merc in that the anti-ventilation plate should be at the surface or out of the water when running WOT on plane. I would try raising the motor first and see what that gets you. If you're still having problems, retrim the ballast in the hull to move more weight forward amidships (past the halfway point from bow to stern) and give her a test run again. I think you will find that by raising your motor, you'll have less drag in the water and will get that bow to run flatter. Most porpoising in a jon boat is cause from too little weight forward. Just my .02 cents. [/QUOTE]
