1977 140 Evinrude Tranny Probs (still)

[Madracer]

Ok I'm Back for more brain food. Today i took my boat to the lake to try out the adjustments that I had made to the shift cable. I put boat in the water and thank GOD i left it hooked up this time! Engine starts and warms up for a few minutes. I then put in reverse and the CLicking started again like it wants to go into gear but it just wont do it. I also tryed to put it in forward and the same thing, Clicking like it wants to go into gear but it wont.

One thing I did notice yesterday when I started the motor on muffs is that the prop was turning slightly. I have no clue if that makes any differance but thats what I observed.

If anyone can give me more suggestions to what might be my problem I sure would be appreciative.

Thanks in advance,

i do, the prop turn because exhaust is going thur it.

now the suggestion. forget the cable, disconnect it, do as you did, put the boat in the water on the trailer, and shift the motor linkage, manually, if it goes in gear as it should, start considering replaceing cables. are you using a Johnson/Evinrude controller or a aftermarket?

The controller was on the boat when I purchased it a few months back! It is a Evinrude power pilot controller. I do still have room to adjust the cable. I am not sure what to do as I am Boat Motor illiterate. I wish my manual would hurry up and get here! Sometimes I wonder why I wonder! I will try the putting into gear manually at lake tomarrow if the weather permits. Supposed to be raining and storming in Oklahoma.

:redface: Ok I adjusted the cable again this time i did notice a felt differance in the controls. I figure I do need a new Cable as This is a very old boat and motor. I will try this out tomarrow and see what happens, if nothing else I will leave the cable off and try it on the water just to be sure.

Thanks for your help I do appreciate it very much,

You should be able to shift it and make adjustments with it running on the muffs. Just make sure that everything and everyone is clear of the prop and then shift it into forward and reverse with the motor running. That could save you a wasted trip to the lake. If you take the cable off put the shift lever into neutral and then adjust the cable to the lever position. Try it by hand without the cable before you hook it back up.

he could put it in gear manually on the muffs but there would be not pressure on the prop and it could appear to be in gear and turn the prop with no load it need to be in the water and put in gear manually so there is pressure on the foot cause the foot could be slippin and with no load it may not be noticed i would say drop it in the lake and put it in gear manually and see what happens

No expert,but I think that gearcase is a cable operated hydrolic unit similar to the Hydro-electric modles of a few years eailer. Be that the case they take a different lube and are sensitive to dirty or water filled oil. Sounds to me like the oil pump is not able to move the clutch dog enough to mate the gears.
It is an easy thing to check and I would start there. Hope this helps, Good luck. P.S. go to "shop evinrude.com" and pull up your gearcase you can see the pump and shift mech. there.

The shift does use hydraulic assistance but standard high viscosity marine gear oil is correct. If the oil is low or missing, the hydraulic unit will not function, naturally.

Re: 1977 140 Evinrude Tranny Probs (still)

so when I check this gear/hydrolic oil, what exactly am I looking for?

Re: 1977 140 Evinrude Tranny Probs (still)

Just that the gearcase is properly filled with gear oil. -That's usually the first thing you do before running a motor at the beginning of the season.

The oil is inserted at the drain/fill plug near the skeg until it flows from the vent hole near the top of the gearcase. Then the vent plug is replaced, followed by the drain plug. Both need new washers.

I will go out and check that right now! I have so much to learn about boats and motors. Maybe someday i'll be able to pay someone to work on it LOL. I appreciate everyone here helping me out. You are all the greatest!

Thanks

Re: 1977 140 Evinrude Tranny Probs (still)

Ok i just came in from checking gear lube and checked tranny without cable again. goes into both reverse and forward fine by hand. Hooked cable back up and readjusted and it seemed to go into gear fine both reverse and forward. when I checked gear oil it came out the hole. What color is gear oil supposed to be? mine was thick and milky white in color. Is this right or is it the same as a blown head gasket on a car and turns white when water gets in it? Again I appreciate you guys helping me, I cannot tell you that enough. What do I do next?

Re: 1977 140 Evinrude Tranny Probs (still)

It turns milky when water gets in it. That could be the result of bad seals on the plugs, but could also indicate a bigger problem of bad seals on the drive shaft, shift rod or propeller shaft.

A pressure and vacuum test at your service department will determine the source of the problem.

Worn out oil will also smell as though burned and will appear black. The original color of the gear oil depends on the manufacturer.

Re: 1977 140 Evinrude Tranny Probs (still)

Ok, I am going to purchase the seals on the plugs and new gear lube tomarrow. I will try that and see if that helps and after a day of running I will check the oil again and see what comes of it. Hopefully it wont be milky white. Honestly I didn't check hardly anything on this boat and motor when I purchased it. I did make sure that the motor ran but I never put it in water just muffs. I only paid 800 for it, so I was like a little kid. If i have to ask questions to fix it i suppose thats what I have to do!

Again I do appreciate all the help you all have given, I have found that everyone here is more than helpfull when it comes to anything about boats and motors.

Thanks,
