"I have a 1990 Wellcraft 3300
"I have a 1990 Wellcraft 3300 Costal with a pair of 454's w/ Qjets. After sitting for about a month I fired up the starboard engine on the fresh water flush system. A big cloud of rust colored crap flushed out at start up .... wtf. I always flush the salt out with fresh water and salt a way after use and the entire cooling system including manifolds was replaced/rebuilt 4 years ago. The port engine does not ever do this and the starboard started, or I should say I noticed this, several monts ago. After sitting it looks like I'm flushing a bunch of rusty water out of the exhust.
I'm very worried because I fear water in the heads... any advise or tests or past experiences are very welcome.
Other than this "issue" the engines and boat runs great and have never given me a problem.
