Do you have a fixed or folding prop? If it''s a folding prop, it sounds like one blade isn''t open all the way. To fix this on our boat we put the boat in reverse for a shot, to get the blades to open fully, and then quickly shift to forward. If you''ve got a fixed prop, it sounds like things may be out of alignment..... If it''s not the motor mounts (the first thing to check), it gets less and less fun after that.
