Be very careful putting that much oil in! I have a Milodon oil pan on my 565 that holds 7 quarts. I find it hard to believe that yours holds 9 quarts ... If you've replaced the dipstick, then find out how much your oil pan is supposed to hold, fill it with that much, then mark the dipstick...

Too much oil is worse than being low on oil. The counterweights on the crank are going to be splashing thru the oil, causing hydraulic shock. Kinda like what would happen if you stuck your arm in the water in a speedboat going 60 mph...
