Working with a 9.8 (ser# A113299). When you start it up you get exhaust out of the tell-tale. On the engines I am used to working on I would think I have a blown head or exhaust cover gasket. The engine does over heat, have installed a new pump impeller.
Sounds like the cooling system is being pressurized and causing the engine to overheat.
What say you?
