Hello everyone. I have worked in auto engines and marine diesels but I am looking for advice on working on the Mercruiser 8.2 EFI engine. 1996 model. 89 engine hours. Been sitting for 10 years.
The original exhaust manifolds need to be replaced.
1. I have never seen exhaust bolts this bad. I was able to remove some of them, but others are so rusted you cannot even see a bolt head. I thought the best course of action would be to use a die grinder to grind down what is left, maybe go down a little into the mounting flange. Any suggesstions?
2. My manifolds have silent choice mechanisms bolted to them. I don't see such threads tapped into stock manifolds online. I suppose I just drill and tap them?
3. On install, just a gasket? No sealer such as Aviation Form a Gasket? how about the bolts, do I need sealer?
4. Any other novel issues I should be aware of?
Thank you
