Hello everyone,
I've got a 1996 Glastron I/O with a 4.3 LX Mercruiser with Vortec heads. This boat has only been on one freshwater lake it's entire life. Hours are less than 1200. I see no signs of rust anywhere along the exhaust system. I've been working to ensure this motor and entire boat are in tip top shape since I bought it a 2 years ago. With the help of many folks here, willing to share their experience the boat has come a long way. Thank you! The motor/boat has only been lightly used since I bought it. It has a no point shown any signs of overheating. Given it's age and considering it's a cast iron exhaust system, what type of inspection would be recommended?

I've been reading about how long things like this tend to last. An inspection is long overdue.
