If this was salt watercor contaminated water, then the only chance is to immediately remove the battery and rinse the Phone several times in clean pure water to remove the conductive salt / contaminated water. Then leave it to dry out in the sun or in a warm place for a few hours until all the residual moisture evaporates & drys out. With any luck the phone will turn on and work. If it was left with salt water or contaminated water for a long period before rinsing this may lead to permanent internal damage.
