Well, I just bought a 1989 sailfish 255. Yesterday i realized that all the thru hull fittings located amidship on the waterline port and starboard are cracked. Does anybody now how to get to these in order to replace them? Also, the livewell drain and the port box drain are both broken off right under each compartment. HAS ME KINDA WORRIED. Any light on the subject would be greatly appreciated. BTW. I LOVE MY GRADY and cant wait to put it in the water.
