	Did you put the raw water pump in upside down? I have no idea what you are talking about as far as water coming out of prop shaft bearing so I can be no help there.

	2005 year of rooster. but it all taste like chicken. I have no idea how you can get water out of prop shaft. But check the trans cooler for restriction. Also your impeller should have a direction. That's what cause's it to suck. Really suck's if it go'es out on you when your out on the water.

	definitely check transmission heat exchanger. If there are leaks water can fill trans case, mix with rans fluid, and cause over full, over pressure situation. trans fluid water mix would be smelly, oily mess. Trans cooler should be about $100 from skidim. It's the trans rebuild that is going to cost the big bucks if this truly is the problem.

	some time I don't check this forum,sorry for late be here, few days before I checked the boat,I found the raw pump install upside down,so it don't suk water but shoot water out from cleaning inlet,I reverse it and test by pipe water,water come out soon and plenty,(I changed flush kit and change raw pump impeller last time),I'm not yet test the boat to sea. SO I asume my boat first problem is flush kit air leak. How do you think?
