Hard to say. Drain the gear lube and pressure check the drive and find the leak.
.... I have also replaced gears and other components in lower units....
Just wondering if this is a Seal issue? It started coming out the small hole soon after filling the gear case; normal filling by the bottom drain hole and pumping oil in until it came out of the vent hole.
Any ideas?
Thanks
I've got an Alpha one Gen 2 and mine has a very small leak out the weep hole. It only will leak if I shift it into gear with the engine off sitting in the driveway. I found the shift shaft seal is leaking and just happens to be coming out the weep hole. Take a look at the shift shaft and see if there is oil around it.
Hy dymd3z and welcome to iboats forums! I recommend you copy and paste your first post into a new thread started by you. Also provide as much info about your equipment as possible (model numbers, serial numbers, operating history, etc). It will then allow the forum to concentrate on you problem and it wont get lost in the other person's thread (also known as hijacking....pretty crude term, but it is what it is).
Best of luck in getting your issue addressed. I'll look for it in the new thread and I am sure you will get the personalized help you need.
Also, please go to the top of the mercruiser forum and open the threads called "stickys". They will provide you (as a new boat owner) with a wealth of information and links that you need... particularly you should download copies of the manuals for your engine and outdrive. If you are like me, you wont be disasppointed!

I finally got a chance to remove the lower, drained the remaining oil and gave her a little pressurized air into the weep hole and crap came flying out past the shift shaft. All the seals could probably be replaced in this 1972 clunker. Just wondering if I should even attempt any repairs or just call the guy and say the parts are NLA. What do you guys think?
SEI lower for about $600 is even cheaper than stripping the box and putting new seals in... It's a 'no-brainer' for me...
Ok...hmmm...let me see if I understand what you wrote. You say you did the pressure test "into the weep hole"? I think there is a GCE here.... No doubt blowing air into the weep hole would blow crap up and out of that area, and "past" the shift shaft (area)..... But what about the pressure test of the oil chamber? Got more info? KTB
I don't know what SEI means, I presume it is a rebuilt lower. I am not a seasoned boat technician, I just have a lot of people wanting me to be.
I drained the lower, the first place I added air pressure was the lower drain/fill plug, it seemed to hold ok, then I decided to blow into the weep hole. The spot where I noticed the fresh oil look was the small O-ring seal on the top outside edge where it meets with the upper housing, the shift shaft seal has what looks like a seepage over time (not fresh leak).
Thing is, this guy brought a new prop in also, and he claims it is hard shifting too. So, just wondering how much time and effort should be exerted towards this thing.
