Lower Unit Lube Type (Johnson 60ESL71C)?

[Zep--]

While I'm still on dry land..figured I'd change out the LU gearcase lube.

Should I be using the Type C Premium Blend Gearcase Lube or Hi-Vis Gearcase Lube in this model?

Thanks!

premium blend only

Any secrets to putting it in F-R?

Or just pump it in from the bottom hole till it comes out the top hole?

Like after I empty it, should I try to flush it out with something first to really clean it or just drain and refill?

Thanks!
Carl

Flushing those lower units out with ATF works very well. Fill from the bottom hole as usual until it comes out the top. That type C stuff is so thin, I usually top it off from the top before installing that plug.

By ATF I assume you mean regular old Automatic Transmission Fluid?

I'll give the ATF a try tonight then unless someone else has a better flush method they recommend.

Should I put it in (the ATF) and crank it a bit without starting it to loosen up any leftover junk in there and then drain it again?

Thanks!

Auto Tanny fluid, yes. Run the engine for about 5 min. drain and refill with Type "C". Cleans 'em right up.

Thanks DR! I had a HELL of a time finding Type C Gearcase lube, but finally found a dealer who carries it and will be picking that up tomorrow and some ATF to clean it out.

Thanks!

I forgot to mention. Shift the thing several times while it's running with the ATF to get all those micro-hydraulic lines flushed out. Good luck.

Will do! Thanks for the tips!

Hey DR. I did what ya said..ran it on idle on muffs, 1 minute forward, 1 minute reverse, 1 minute forward 1 minute reverse. 30 secs forward, 30 secs reverse.

5 minutes total on idle with muffs on.

waited one minute after stopping motor.

The tranny fluid went in that bright translucent red color and came out whiteish pink.

Now..is that just because the tranny fluid got airated in the LU or do I have some kinda water leak?

I may run another quart of tranny fluid thru it tomorrow, but wondered if the whiteish pink color was normal or if I have some other problem?

Thanks!
Carl

Sounds like a water leak to me. It should come back out close to the same color. I'd put a seal kit on that lower unit before you run it any more.

if you cought that oil in a pan pour it in a see through container if its water it will seperate and be on the bottom in the morning

Re: Lower Unit Lube Type (Johnson 60ESL71C)?

Well, I caught it in a wet bucket I had sitting in the boat (been raining here). I'll run another quart of ATF thru it and try again in a clear container.

Thanks!

Ran a 2nd quart of ATF thru it for 5 minutes. 2 1/2 minutes both forward and backward,

waited about 5 minutes after stopping motor.
came out dark red but not see-thru like when it went in. not whiteish pink like the last last time though. It's in a clear container sitting in the kitchen. WIll check in the morning for water seperation.

The stuff I drained out of there initialy was very thick, light brown mud colored goop. I thought Type C was a thinner gear lube? If so, I'm guessing the last owner put the wrong stuff in.

I may run 1 more quart of ATF thru in the morning if I dont see any water in this lastest test.

Thanks!

Re: Lower Unit Lube Type (Johnson 60ESL71C)?

Zep. The seals are not hard to change on that motor and they are really cheap too, relatively. About $20 or so. If you're getting water in the oil just from running the muffs, I'd guess it's the seals on your waterpump itself, or worst case scenario, the shaft has been worn down too much to make a good seal anymore. Have you looked at it? Those seals are easy to get to and change if that's the problem. If it's the shaft... Priceier for sure but still something you can do yourself. Get yourself a manual and tear into it. The thing is running and still shifting okay so you're 9 tenths of the way there. But you need to stop that water from getting in there because those solenoids don't like water. If they rust, you're done.

Re: Lower Unit Lube Type (Johnson 60ESL71C)?

I've got the Seloc Manual 1306. It sure makes it Look complicated.

Even says in the manual "You'll surely break a few bolts trying this"
or
"You might have to hack-saw thru to remove the LU and then re-weld it later."

From looking at the manual and the directions I cant even telll where the water pump is

Thanks!

Re: Lower Unit Lube Type (Johnson 60ESL71C)?

It is possible some of the bolts could be frozen in there, expecially if it wasn't put back together properly the last time. But, if you haven't taken it off yet, you need to at least inspect the water pump impeller anyway. Or just replace it if you don't know how old it is. Another $20. Just follow the directions step by step and as long as the bolts break free, you'll be fine. You really have no choice except to take it to a shop $$$$. Running it that way will ruin it.

Re: Lower Unit Lube Type (Johnson 60ESL71C)?

let the ATF I drained sit overnight, still looks the same. there is a little seperation of something at the Top (1/64th of an inch worth) but not the bottom. The very little stuff at the top looks like clean ATF tho, not water

I really don't see any water in it. I think whatever was in the LU to begin with was just very old.

I'm going to run 2 more quarts of ATF thru it and check each again for water after draining before I put the TYPE C in.

I did notice while doing the ATF cleaning the Top vent screw had no seal or rubber o-ring on it and the bottom drain screw has some kind of thick hard amber see-thru washer/seal type thing.

Thanks!
