I have 8.1 Mercs and replaced the manifolds back in 2017 (5 years old now ). After EVERY ride I flush both engines with fresh water before calling it a day. I'm thinking of replacing after 7 years. When I replaced my Transmission this month I also replaced the trans cooler. No kidding, it looked BRAND NEW inside. I'm just wondering if I should just take a look and replace the turbulator gasket.
