I am having trouble with lower

I am having trouble with lower unit leaking I am missing the white plastic piece in the water intake and now am losing oil. Also leaking water from the front right bolt where the lower unit meets the motor leg when the motor is raised. Any advice?

That white plastic piece is a strainer to help keep crud out of the pick-up. Not the end of the world, but worth heading to Merc and getting a replacement.

The water leaking when tilted is somewhat normal. There is no positive seal between the gear housing and the exhaust housing. The exhaust housing in normally filled with water. Most goes out the exhaust, plus there is at least one relief hole to help the last of the water to exit so it doesn't freeze and crack something. That extra little leak is not hurting anything.

Your last issue, losing oil. Do you simply have black, burnt smelling oil dripping from around the base of the prop or out the prop itself.

That too would be normal. All the burnt/unburnt oil and gas goes right down the leg and out the prop.

You normally don't see it because it ends up in the lake and it ususally doesn't drip unless warm. So even when you haul it out of the water, it drips on the road during the trip home. But sometimes you will see it on the floor of your parking spot.

Gear oil is usually a honey colour, if this stuff is black, it's just exhaust oil..."
 
It is the honey color and is c

It is the honey color and is coming out mostly from the water intake so I'm wondering if the water tube coming up from that strainer may have cracked or broke off letting the gear oil out?
