It appears that I cannot replace the exhaust manifold gaskets without pulling the power head. Two lower bolts holding the covers on are not accessible. Not enough clearance between the bolts and engine cover or casing. A bigger job then I am able or willing to take on. I talked with my local marine shop and they estimated about 8 hour and between $800 -$900. What would prevent me from drilling two access hole through the engine casing or cover giving me access to the two lower bolts? After the job is complete, just cap off the two holes with plastic, rubber or metal plugs?
