    Evinrude 55 1978 gearcase

    I would not call it mixture of grease and Permatex, but after carefully cleaning extra sealant from rubber lips, I oiled the lips to keep them flexible. I was just wondering whether Permatex hardens the rubber parts or not. I think Permatex is same as OMC, Evinrude / Johnson gasket sealing compound.

    Evinrude 55 1978 gearcase

    I used Permatex Form-A-Gasket 3 for oil seals, it seemed to overflow a bit to innner side while pressing seals in. I tried to clean the extra sealant and "lubricate" it with water resistant grease. Does this sealant tend to harden the seals?

    Evinrude 55 1978 gearcase

    What about the use of any sealing compound in new oil seals and gaskets, I'm not in favor?

    Evinrude 55 1978 gearcase

    I was wondering what is the purpose of those three slots in this drive shaft cover? Another question concerns the metal parts (e.g. springs) of the aftermarket oil seals which are not stainless. Is it always so in the aftermarket parts as the original ones are stainless.

    Evinrude 55 1978 gearcase

    I am replacing the drive shaft oil seals and found these numbers in the old one. The last two numbers are strange and as far as I know they should be 66 (#321466)? Numbers are very small to read, but this is what I got. Any experience on this part number?

    Evinrude 55 1978 gearcase

    I don't know whether it was easy or not with a small screwdriver, but it is done. Seal seems to be so good that I don't know if it needs to be changed at all. I was just thinking, as the gearcase is open now, if it were good to change the driveshaft seal as well, but maybe I don't do it.

    ... yes, the methods in the videos may easily cause damage and new problems :). O-ring change seemed to be everything else but simple

    I found one youtube video which shows the entire process for lower unit seal replacements.

    Evinrude 55 1978 gearcase

    I have two questions concerning this lower unit: how should the O-ring inside the shift rod cover be changed? Is it possible to remove the brass mid part (bushing?) ? Another question is about a small hole in the trim tab. Does the water flow assist someway the exhaust gases to get out through...

    Evinrude 55 1978 gearcase

    I'm not afraid that crack will increase at all (it's been there over ten years), the only concern is a small leak there (not increased at all during those years) and I think JBweld could help a bit in this problem.

    Evinrude 55 1978 gearcase

    I think I can do it with this JBweld, but the problem is that the crack is probably in the threads of the drain plug and then I am not sure if the nylon plug gasket prevents the leak.

    Evinrude 55 1978 gearcase

    Hello, I have owned Evinrude 55 1978 since 2013 and it's been working well. Now I first time decided to change the water pump impeller and after removing the gearcase I found that a lot of exhaust gases must have been leaked inside there (black soot). In the figure (arrow) it can be seen a leak...

    Evinrude 15 firing on 1 cylinder FYI

    This is how the prop may look when the motor runs on one cylinder :)

    Evinrude 15 1992 carburetor cover change

    The conclusion here is that the new cover does not fit the carburetor. So, I got one older carburetor and everything is fine now. I was told that the carburetor now is from 10 Hp, but I don't know.

    Evinrude 15 1992 carburetor cover change

    Evinrude is not yet idling. I cleaned the carburetor, but it still idle only with choke. I started to think about the carburetor cover gasket (in the kit there are usually three different gaskets), if it is not the correct one. Anyone here who could see this from the pictures above?

    Evinrude 15 1992 carburetor cover change

    How important is the air silencer seal for this Evinrude's idling? It may run a bit lean as more air is available, but I guess it is not an issue (seal was missing).

    Evinrude 15 1992 carburetor cover change

    Yes, the cam follower touches the cam at sync mark when tiller handle is in start position. At this position carb should just open a tiny bit or not at all. I adjusted cam roller to advance a trottle a bit more. I think I cannot change the link and sync any other way?
