well i took outdrive off,it fell off by itself so align ment was close to perfect i'd say. Take al look and see what you think but it looks well taken care of and serviced . gimble bearing smooth. some liquid in bellows but not water looks like thinned grease. the ring on shaft is melted rubber not grease. I am going to use tungsten marine coupler price 80.00. We will find out if they last or not .
any comments on pictures let me know. out drive pre alpha but which one i dont know serial # s are hard to read.

Even if the outdrive came off easily, be sure to check the alignment with the proper tool. The ujoints, etc look good!

Re: bad coupler outdrive pics

You didn't show the coupler, and I never heard of a "Tungsten Coupler" before.
If the splines are out of your coupler, then alignment check would help because there is nothing ther to check. The splines are gone.
Look straight in through the gimbal bearing and look for splines in the coupler, not on the shaft that goes into the coupler.
The coupler has alum. splines and the shaft is steel. Want to guess which goes bad first?

Re: bad coupler outdrive pics

will align engine gimble bearing when i put new coupler on and put engine back.
Tungstenmarine .com i think is the web site,imported parts but worth a try.But most parts are probably imported. really counldn't get good pic of coupler being it is way in there and i think melted rubber is preventing good pic.
yeah your right ,alighnment might have been off but spun coupler would not be accurate.Any ways it looks like good maintainence made it easy on me. bellows look good i dont think i will mess with them. Gimble bearing must have been replaced because it is baby smooth rotating it.

As easy as it came off I might take of every winter and store inside and start fresh in spring,

Re: bad coupler outdrive pics

From what I see, you have serious lack of maintenance. That gray/milky gear lube is water and oil. Either from the drive or water getting into bellows. You probably have a sticky gooey mess of gray sludge in the drive (wrong gear lube) , needs drained and drive pressure and vacuum checked to find the leak.

Re: bad coupler outdrive pics

swapped gearlube twice last year alone with synthetic merc, doesnt feel like water but not alot in there , As a serious lack of maintenance i dont think so outdrive is almost 40 years old, I like to see another one that would look much better. I have seen newer ones that dont look that good. I check gear oil every time i get home. might not now much but i know that is the most important.
as the gooey stuff maybe 3 tablespoons in there . I can live with that after 40 years. could be from running on ears and pressure to high by accident. pressure test before i put it back on was already planned, I think it looks pretty good was expecting alot worse from seeing others. Tell you what i was on the last day of vacation pulling tubers and beating it on it pretty bad trying to keep 10 kids laughing and having fun so outdrive is a good one.learned my lesson and wont get carried away next time. coupler change and tuneup,oilchange and should be good to go .

Sorry, but how can water pressure on muffs result in water in the bellows? I never pay attention with muffs--- what am I doing that could be problematic? :confused:

City water pressures can be extremely high...and easily force water past the internal seals in the outdrive. The rule of thumb is to never open your spigot past half way, when using the muffs.

I remember reading on this forum (from one of the resident mechanical 'gurus') that the water pump seals were designed for something like 15 to 20 psi max (someone will correct this, if my memory is shot). My local water pressure is almost 85 psi....

Re: bad coupler outdrive pics

Unless you clamp the muffs on somehow, any excess water and pressure with simply leak out past the muffs. Even if you did somehow "blow out the seals" - and the water somehow got into your outdrive, you would be showing evidence of water in your outdrive oil.

If the original poster's outdrive oil is good, and if the sludge in the bellows is from water, then the water had to get in somehow other than due to high water pressure through the muffs.

I don't know what caused the grey sludge - maybe just too much grease in the gimbal bearing? :confused: It seems to me if water was getting into the bellows area, that the u-joints would be exhibiting some signs of rust... and they are not.

The other grease in area looks good i thought it might have come at the oring in picture a little but i dont know just guessing but lower oil looks good.

Ah, that is why, My earmuffs are leaking like a sieve while the engine is not running... once the engine is running, there is very little running out from the muffs...

Always better with a second hand around, but normally I just let it run...

Re: bad coupler outdrive pics

my coupler did not knock it just went like i thru in neutral.
Not much back there but gimble bearing and u joints , maybe a rod knock, as it is running pull spark plug on one cylinder at a time and see if it goes away or gets quieter. Used to use that on v8s dont know how that will work on 4cyl.

Re: bad coupler outdrive pics

By the way i being newbee did the first time i ran on muffs open water full without running engine. i turned off and checked my oil and i had a little clear water in there so i know you can have water get past seals. best to open lightly then when running open up some more , two person job. after vacation did not have any water in oil. I am going to try to pressure test somehow.still worries me but i try not to think about it. And water did shoot out past muffs and that didnt help. My city pressure is 55 lbs or so.pressure test is 15 lbs i think.
