1980 35hp lower unit removal cant remove cotter pin

[comet424]

hi i took the lower unit apart and trying to get the shift rod out unhooked from the cotter key inside the lower end i straightened the cotton pin basiclly with long needle nose plyers but i cant pull it out i tried using a hook scriber and to pull it up through the loop at end all it did was ruin my scriber

is there a trick or a stronger tool to use?

 

[racerone]

STOP-----There is no need to remove a cotter pin to take this lower unit apart !!

 

[comet424]

nevermind i figured it out you can use a screw driver and screw it out shaft and the thing came out

i need a new whatever is busted its in pieces they never had oil in this unit its all gray color or the seals were bad

id like to remove the 2 gears to inspect it and to wash it out with gas for any fileings how do i do that?

 

[comet424]

the pics i forgot

 

[comet424]

oh and i also removed the 2 seals at the top where the shaft came down from the engine..
i guessing i have to remove the bearings but not sure how as id like to wash this unit real good

 

[comet424]

so i guess that was [h=2]SHIFTER,Clutch dog[/h]
but also this doesnt have the [h=2]CRADLE,Clutch dog[/h] i guessing the engine chewed it up in pieces as it wasnt in there

but there is sluge i guess and there is a spring in here too in the \ [h=2]LEVER,Shifting[/h]
here some pics

I just needed to look at the first picture !!!------This lower unit is garbage!----Look for a good used lower unit.-----Lots of them around in southern Ontario.----With new parts the repairs to this unit will far surpass the value of the motor.

 

[comet424]

looks like that bearing is shot and rusted in place doesnt move easily how do i pull that out was trying a bolt head and trying to pull out is there a tool to pull that out

 

[comet424]

oh ok ill ask around then so its not worth fixing it myself then what would have happened? water seal and it just went nuts

is there a website i can ask for the lower end? or just ask marinas... well i done working on it tonight if its not worth fixing i done trying tonight ill look online

 

[comet424]

i googled it but no hits... would you happen to know what other years this lower unit would be compatible with that were used on different years i might try to look for as well

Next step is to evaluate the powerhead...--No point in spending time / $$$ on a lower unit if the powerhead has been subject to the same level of maintenance!!--Your location is ?

 

[comet424]

im located in Hastings, Ontario Canada

how do i evaluate it? ill take some pics just a moment and can it hook a hose up to the water pipe some how to run the engine or so

 

[comet424]

cant test for compression today.. but what color was this engine orginally as maybe the water pump didnt work as the heads are brownish color

might not even be worth to rebuild it either

 

[racerone]

A " running " engine means very little to me.---Condition is all important.---The condition of the lower unit indicates to me that the engine never had proper care !

 

[comet424]

ah ok well i cant tell what condition power head is just from pics i just took i guessing maybe the heads shouldnt be brown i cant tell i not sure if it was brown years ago or also gray im guessing gray ... and i think it over heated..

so i not 100% sure but ill do compression test tommorow to see if it even has compression but cant tell if head gasket blown... always something i tell ya

 

[comet424]

well i just reinspected it closer... so orginal color was gray and the heads are brown so water pump failure and i turned over by hand so it does spin feels like compression no wires melted just the heads are brown... least thats all i can tell with out a battery to turn over.... and cant tell if it was running to lean?? to have caused it over heat? or would that just be water pump

 

[comet424]

so I got the engine running... here is video
https://youtu.be/A80yWRtJAOk

the gas tank had no fuel in it was water with the smell of gas in there.. and white pieces in there and the o ring and the float for the fuel cap in there guessing the metal bar is in there too... in those portable fuel tanks.... so these people didn't care at all... they basically drove it into the ground

the compression on both cylinders is like 133 psi maybe 135psi

you mentioned there are places that would have this lower end in southern eastern Ontario.... Im close to Belleville or Peterborough Ontario in small town of Hastings Ontario.

the 3 places I contacted so far don't have anything that old... maybe if you know of a place you can direct me to be great..

I appreciate the info you have provided so far

You've got all winter to find something. I would guess that any of the 1980s era through hub 20-35hp lowers with the access window for the shift rod in the water intake would fit, but I do know there were subtle changes from year to year. Yours had the two lug clutch dog, while later ones had three lugs. Should swap as a unit, but individual bits are different.

Make sure you get one the proper shaft length, as they came in short and long shaft flavors.

Try an ad on Kijiji or Craigslist for a parts motor. Might get a whole motor for cheap!

If power head checks out and you keep this you will have to find a lower unit from a 1980 - 1983. In the 1980 model they changed a lot, biggest being the water intake and water pump. 1979 and older will not fit. Then in 1984 they changed again and the 1984 and newer will not fit.

I know this because I had a 1981 with a blown lower and I searched for almost 3 years to find a nice used one. Eventually I sold the power head to someone for parts.

 

[comet424]

ok I can do that..look over winter... how do you guys know what lower ends fit other then experience... is there a page that will say 1980-83 units fit...
and I have the shaft out how do I know if its a long or short shaft?

ya I figure ill fix it up all needs is the lower unit.... if not ill just sell it and try to find newer
