View Full Version : Pro Star 1989 Exhaust issue maybe?

07-29-2012, 06:32 PM

I was cleaning the back of the boat today and realized my exhaust flapper seemed loose, upon removal I found it to be melted on the right side. I realize it is exhaust and it gets hot but this seems too hot.
The left side looks to be what i believe to be normal.

Does this look normal, just old?
Any ideas on what would cause this?

Boat runs consistantly 170 - 180 degrees all day.

1989 Prostar 190 351

Thank you in advance for any and all imput.
