Now from the picture of the Bravo 1 outdrive you can see that the outdrive is missing the fin that is located on the bottom of the outdrive which looks like an upside down sharks fin. So, you would have to pull the lower outdrive off and replace the Fin. And probably have to change the gimble bearing too. The shaft that holds the prop looks good and straight which is good news. You might want to check the tilt motor for the outdrive to see if the tilt goes up and down and also check out the oil inside the tilt motor to see if it is pure oil and not milky or creamy. Then you might as well change the outdrive oil too. On the engine if I were you I would get a local boat mechanic to over look the engine. (Their are some marine mechanics under marine services on Craigslist .com that will only charge for an hour or two) from the pictures of the engine it looks like it is not in that bad of shape for a 1984. From what I can say so far the outdrive needs to be pulled The engine might need a rebuild as it depends on your budget and how much you are willing to put in the Chris Craft but after that is all done you are going to have one heck of a nice looking Chris Craft Scorpion. The next time when you go see the boat take some pictures of the whole outside of the boat to show what looks is like.:D

Here is a Video to give you a look on a Bravo 1 outdrive. http://www.youtube.com/watch?v=NYFXJhOE8Y0

Just squirt regular engine oil in the cylinders if need be? WD40 will wash the cylinder walls and cause excessive friction on the piston rings. Regular oil will lubricate and seal.
Crank it over and see if there is oil pressure also. One way to test this without turning the engine over is to remove the distributor and using a tool (I made my own)that will fit into the oil pump , hook it to an electric drill and spin the pump. You should see pressure on the gauge. If you do, the pump should be ok , so put distributor back and try to turn over the engine to see if it starts.

that outdrive is an alpha 1. |Someone has droped that big block in that boat. that boat should only be a 350ci engine. The alpha will handle the big block power just be easy on it
