We are about three months into our 1980 CHB 45. Twin FL 120’s 1800 hours. All previous owners did a great job maintaining the engines. Now it’s my turn. Been on boats all my life 45+ years. First experience with Diesel engines.
Exhaust elbows showing some serious signs of corrosion. Purchased new elbows from ADC. Got all the bolts loose, which I feel like that was lucky. Noticed coolant dripping from the bottom of the elbow. Didn’t expect that. Hit pause on the project. I wasn’t equipped to handle a coolant dump. Do I need to drain the coolant before pulling the elbows off? Or is this just a little residual.
