Took carb off and checked it since previous owner did not put in fuel stabilizer. Carb had water in it. I bought a new marine carb but noticed the inside of the intake manifold was rusted. Will this need to be cleaned out or replaced ? Any info greatly appreciated.

"Probably just moisture. I hope the guy winterized the motor properly, and that the block isn't cracked.
