The trim of the outboard is one place to look, as mentioned above.. If by 'foil' you mean those fins they add to outboard cavitation plates, that might be worth investigating, but I'd be skeptical.

You may be powering on too hard (and likely not gaining any speed anyhow) so throttle back to reduce the 'squat' and see if things go better then. But also check the trim pin on the clamp bracket.. if the motor is tilted up aft, that will promote the 'squat' that's giving you problems. Try going to the lowest pin setting there.
