Good luck and enjoy!
Before launching the boat, I'd
have the outdrive remove and make sure that:
The bellows are not leaking water, the gimble bearing and u joints should be checked for wear and greased. The outdrive should have the gear oil drained and pressure checked. The shift cables should be checked for free movement. The engine alignment should be checked when the drive is off. These are all things that if they are neglected will cause trouble once its in the water. So it should be done now. This is what I do with our boat every fall.
If in salt water (where slipped? Med Sea?) keep an eye on that joint between the exhaust risers and the exhaust manifold. If you see any sign of leaking, the risers should be removed (drain manifolds first) and the exhaust checked out. Because if they leak salt water into the center exhaust passage it will rust exhaust valves and cause a lot of trouble.
I am not a fan of Volvo's and the older Merc style manifolds in salt water. There is not much material to seal that gasket and when it gets corroded you have problems. I like the Merc dry joint system better and when my boat needs manifolds next time (probably in 2 seasons) I am going to adapt a set to the old OMC V-6. Already figured out how to it
