1993 Chris Craft 380 - Couple questions

Hey Guys

First of all thanks for all the advice on hooking all my Batteries up, I followed it and everything works perfectly now. I just have a couple of more questions and then I think I will be done all the Mechanical.

1. I have a slight leak (drip every 3 seconds) under my starboard motor where the V drive shaft goes through. Of course it is impossible to get to and it doesn't seem bad enough to warrant a haul out now....thoughts? I am not even sure what that is called.

2. For some reason my Port motor's exhaust is loud(ish), my starboard motor is dead quiet. Any thoughts?

3. Port motor again, on the bottom pulley there is something that comes out with 2 coolant hoses attached. It seems to be wobbly, on the other motor it doesn't wobble at all. Can I fix it?

Again, thanks in advance for the help!
