2005 Yamaha 4 stroke corrosion

Had to replace power head last year due to corrosion. Engines were running great. Boat was taken out by Marina in October winterized etc. Boat was put in water last week when I started the up star board engine was spitting out water from exhaust relief port. I have attached a photo and a video . Oh yea they replaced poppet also. Hope this is nothing serious. Port engine does not do this.
