Re: Still confused. Love everyone who helps.

chris, ironic as it may seem, my outdrive seems like it has water on the main drive shaft, since your sooooo knowledgeable about my unit is that normal or do i need to do something else? you are awesome to spend this much time on a boating stranger but listen if i had a offshore bank account i would repay you. hahahaha. anyways man I wish the best of you chris, and I will look at it better in the morning when I have better lighting, (I am working in the back yard right now with minimal lighting, outdrive came off like you said though. LOVE THE VIDEO!!!!!!!!!!!

Are you talking about the shaft that goes into the back of the engine? If so, you should not have water on it. Check the bellows for signs of water ingress.

If you are talking about the vertical drive shaft inside the drive exhaust cavity, then yes, you will have water on that.

Re: Still confused. Love everyone who helps.

here is a picture of the backside... the small puddle is what looks to be water when i trimmed down earlier to look for an air leak i saw water coming out of the drive joint. ACHRIS you are very knowledgeable about boats attached is a picture of what i see.

Re: Still confused. Love everyone who helps.

That's a pretty out of focus picture, but it looks like you have the remnants of an exhaust shutter in the exhaust cavity. If you are talking about water in there, normal. Check the inside of the top bellows carefully. Do you have any water in there?

Re: Still confused. Love everyone who helps.

Good eye on the exhaust shutter, i see it too.

If i'm seeing things correctly, the bottom of the u joint bellows is pushing upwards opening up a big gap to allow water inside.

Re: Still confused. Love everyone who helps.

I also saw that 'bulge' but I'm not sure what it is or if it's just an artifact of the picture being so out of focus. Can the OP get a better shot?

Yes, please provide a close up shot of this.. Right now, I am seeing a puddle of water in the bottom of the drive bellows. Bad.

Re: Still confused. Love everyone who helps.

Sorry that picture was taken with my cell phone in a dark condition I will get back with a better picture, but yes that is water sitting in the bottom of the hose.I will take pictures and post best I can. I have the drive on a stand and will commence to tearing it down. Only question I have is I I read on another forum there may be 7 bolts holding the upper and lower together. I see 5. Any ideas where the other two are located?

Re: Still confused. Love everyone who helps.

okay i am starting the tear down of my outdrive, but i am unsure if i need to remove the bearing carrier and lower shaft, if anyone knows, can I do the tear down without doing that? Or can I just pull the upper and lower apart without messing with the lower shaft?? thanks.

Are you looking at your service manual that Achris sent you the link for in post #3? That will explain it all in vivid detail and exploded diagrams. No...dont mess with the bearing carrier or lower (prop) shaft... just remove the nuts from the studs that connect the drive (as shown in the manual) and lift the upper off the lower (provided you have already drained your oil!!!)


But first..... did you reperform your pressure test with the complete drive removed, so you can confirm that the upper drive yoke seal is not leaking?

Re: Still confused. Love everyone who helps.

Hey kt, yes I have already drained the oil and trying to follow the repair manual that achris has posted, its limited in information though, I don't think its the same exact one I need for some reason, just not matching up the best for me. My bigg mest problem is the part where the upper and lower unit come together/ got alot of issues there, got oil where my water pump is at etc, going to the marina tomorrow for a bulk kit of seals and o rings, hopefully it doesn't cost too much, I will post pictures of alot of stuff tomorrow, mainly questions etc. Biggest one right now is why my gear oil smells terribly like poop. Took the top cover off my upper unit and it just reeks like someone took a poop in my shop. Almost terrifying. Anyways will post some more tomorrow to let everyone know how im coming along. Thanks for the help everyone.

ok... I have checked your drive serial number and it's a GenII, no question. The service manual I posted up for you is for that drive... The separation procedure on page 3A-7 is very accurate and if you follow that step by step you will have no problems. If your drive is not like the one in the book we have some serious problems. Post a photo of the drive.

Re: Still confused. Love everyone who helps.

Good, used gear oil has a distinctive smell all its own.... and not a pleasant one at all, I might add.

haha, it's funny how you said that but the poop smell is normal.

Re: Still confused. Love everyone who helps.

awesome thanks for the good replies. ACHRIS... sorry I DIDNT look at that manual yet, I downloaded one the same day I started this forum but it was off google.com, and apparently it was wrong, thanks for the help. Heres where I am at now, I am going to the marina today to get all new seals and o-rings (for what my budget will allow) for the joint between the upper and lower, including the leaking shift shaft seal which was originally leaking to begin with. also I do not like the water pump so i will check on that as well as others. FEW questions on my adventure while tearing this thing apart. I have two pictures im uploading.

Question 1 is on the picture it has the shift shaft in it, the orifice in front of it has water in it and is not draining out of it... what does that go to? Question 2 when i tore the water pump off there is a rectangular hole on the back side of the shaft that I cannot find any information about, but it was filled with metal rust clumps. as you can see in the other picture on top, sitting beside the drive... can anyone tell me what that rectangle is for? and the purpose of these two holes? thanks everyone.

Re: Still confused. Love everyone who helps.

Question 1. That is the speedo feed orifice.
Question 2. That's just a casting cavity, has no purpose. Just clean the rust out and leave it as is.

When you buy your parts, make sure you pick up a set of water pump housing alignments pins. Part# 91-821571A1....

Question 1 is on the picture it has the shift shaft in it, the orifice in front of it has water in it and is not draining out of it... .

If the water is not draining, check your pitot hole in the leading edge of the drive (looks like a little v-notch). Should be clear; if not, carefully probe it with small wire or pick to clean it out. Might try compressed air, too. (Achris..... does that orifice not drain eventually?)

.... (Achris..... does that orifice not drain eventually?)

It should...

 

[csherrill2]

Re: Still confused. Love everyone who helps.

okay well achris, I took a small piece of wire and cleaned out the hole for the speedo, it drained perfectly, could be a good reason why the speedo didnt work. ANYWAYS, I got some supplies need to replace a few gaskets, spent about 40 bucks at the local marina for the supplies. Changed out the shift shaft seal, it does not leak at all, only thing I have now is it has only been about 35 minutes and im down to 5 psi again. I feared this would happen, the thing I dont want to leak is leaking. The main drive shaft seal is leaking just a tad bit, I completely missed it on the first pressure test since it was so small I couldnt even hear it or see it. my main focus was on the shift shaft seal which I originally found. How hard is it to change that seal? Also while messing around the back of the boat today I saw where I have 2 or 3 shutter valves hung up in the exhaust port, the shaft for the shifter linkage is blocking it. I will try to clear them out. Not really willing to pay 100 bucks for a new set of shutters either.

Re: Still confused. Love everyone who helps.

Seal on the main shaft.... Which shaft, in which housing? We call the top housing the 'drive-shaft housing' and the lower is the 'gear housing'. Each housing has 2 'main' shafts...

Drive-shaft housing... Shaft from the engine, through the uni-joints... and the upper drive shaft.
Gear housing... Lower drive shaft (the one you assembled the water pump over).... and the propeller shaft...

... I will try to clear them out. Not really willing to pay 100 bucks for a new set of shutters either.

You don't have a choice... You need to replace the shutters or you run the risk of water incursion in the engine. Nobody said maintaining a boat was cheap... (If they did, they lied.)
