You shouldnt need a hydrofoil to make an 882 with a 150 plane out properly. Bow rise is normal when taking off and because the NX 882 is stern heavy it will have a little more then other boats. I have played extensively with the setup on my 882 to max it out and there are lots of things i have found. My boat now is a rocket out of the hole and i dont have a foil nor would i ever put on on my boat, i dont like them for many reasons.
Things to check
1) Engine height, the motor should be setup so the propshaft is 3" below the pad, if its too low it will not plane good and may chine walk. If its low have the dealer raise it to the right height. Nitro tells the dealers where to mount them but it seems the dealers dont listen because having the motor mounted low is a common problem.
2) whight Distribution. If you have all your tacles in the back compartments move some of it forward. The 882 is very stern heavy because of where the fuel tank is positioned, there is a lot of weight back there, fill the livewells and its even worse. If you move some weight forward it will help.
3) Propeller. The 882 should have a 23 tempest plus on it. I have found the best combo on the pvs plugs is all three smaller holed plugs in. If you take any out or put in large holed plugs the prop ventilates too much and the holeshot suffers.
4) driving style. One thing i have noticed about my 882, you really cant ease it on plane. the best way to get it on plane is to trim all the way in and mash the gas. Its a high performance hull and it had to be driven as such.
One other thing that will help it plane out better is prop work. Custom prop blueprinting will make it like a whole different boat. It will halp with planing, rough water bite, slow speed planing, speed, turning etc. Nothing i have ever done has helped my boats performance as much. If you want the name of the guy i sent mine too i can post the number when i get home tonight.
