You may be drawing air from the joint where the lower gear housing mates to the support bracket, there is an "O" ring that seals where the parts mate. Also look at the water hose from the nipple to the transom housing sometimes the connection where the hose connects to the nipple it is rotted off or the hose is broken. It is an easy fix if that is the problem . Also make sure the exhaust manifold is not partially stopped up.
