Really though, the drive stuff isn't practical for you to do as experience and expensive tools are required.

Really though, the drive stuff isn't practical for you to do as experience and expensive tools are required.
I nspect the Gimbal Housing Assembly:
With the boat hauled, take a good look at the bellows with the drive
placed in different positions.
Look for barnacle growth, rips and deterioration of the rubber.
The bellows should be clean and firm
A complete inspection will require the removal of the outdrive.
Place the shifter into forward gear and remove the outdrive.
After the rams and the six mounting nuts are removed, the drive should come off. If the bellows have been leaking, the drive might be stuck.
If the drive is stuck, tilt the drive up by hand and let the drive drop back down freely.
The dropping of the drive should free up the driveshaft from the rusted gimbal bearing.
If dropping the drive by gravity still won't free the unit, then some downward "slamming" may be required.
The bearing MUST go in straight. IF it starts to COCK then STOP and pull it back out!!
Take some sand paper and smoothen any burrs that it made.
Regrease and try again. here
Now, take the hinge pin tool with the 1/2" breaker bar and remove both hinge pins.
You will have to turn the steering one direction and then the other to get them out.
Sometimes the pins are stuck. Really stuck. Some heat may be required to free them up.
It may be that you have to actually drill them out!
Drilling is tough and the right size cobalt bits will be needed.
It's important, when drilling, that you don't damage the bellhousing threads! more
Water can get into the drive from a bad seal or a bad oring. Seals go bad after a few years and need to be replaced. Usually drives are resealed every 5 years, less if you have overheated your engine.
If you find water and/or damage, take your boat to an experienced Mercruiser tech right away for repair. Waiting will make the damage worse. here
White streaks are an indication that you have water in your gear lube. This is a VERY serious condition which will eventually lead to serious damage.

If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. here
If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware.

Most likely the U-joint bellows has a hole in it. That will force water into the drive which will cause oil to leak out. It will also cause water and oil to get into the boat. You will need to pull the drive and inspect the bellows.
