Thanks for the information. It seems i may have to take the lower unit off
and take it to a boat shop and have it checked. I don't really have a way of
pumping the pressure up and holding it. I am getting a manual from the
library this week.
Thanks again for the help....Tom

Do i have to take the lower end off of the motor, or can i pull the motor
someplace and have it pressure tested?
I wonder if i fill it up with new gear oil could i take it for a quick
spin? I have done some work on the boat and want to see if everything is
working properly before I tear into something else? I was hoping the oil
seal would be a simple matter of taking out the 2 bolts and pressing the
oil seals off and the new seals on.
Thanks for the help again....Tom

See above^

Here is the basic layout for a lower unit on an outboard or a stern drive.
Almost the same configuration. Look for numbers 35 and 36 (there is two of
them there). You want the top one, the filler hole. You put the pump in
the top filler hole and pressure test to about 12 PSI approximately, or in
the link it says 7 to 10 PSI for that model.

They mention leaving it pressurized for 2 hours or over night. I have
never done that. But this pressure test will show where the leak(s) are
coming from. It's a great way to check your lower unit, and it will
pinpoint where your leak(s) are. Often to get a correct diagnoses, you
have to remove the gear case to check the other seals under the water
pump. You could have more than one area at fault. Also, a good service
manual helps a lot. If anything, it will let you know what you may be up
against.

Hope this helps a bit.

I have a 40 hp Force engine and it is leaking oil from between the prop
and carrier bearing housing assembly
http://coopscorner.com/takealook/carrier_assembly.htm

Can somone give me some hints on getting the carrier assembly off of the
lower gear caseing? Does it have little pins that it slides onto, does
it screw on, do i need a fancy wheel puller or do i need a big hammer
and a block of wood?

I have the 2 new oil seals, but I am wondering if there is an O ring
that is holding the carrier in place?

Thanks in advance for the help, it is very much appreciated....tom
