help with 115hp merc early 70's

[anthony115merc]

i have a 115 merc blueband 197? and a 115 merc redband 1969 the redband had a cracked lower unit so i tried to separate it from the leg but it is stuck very good i had already taken the lower unit off the blueband and was hoping to put it onto the redband becasue i could not get the lower unit of the red one i took the whole leg off the blueband and put it onto the red one it all fits well ecept i cant figure out how to make it shift back to nuetral i have lined up the shifter shaft and it is in but i cant get it back to nuetral.

and also there is a plate between the top of the leg and the motor which comes off i think it looks like it is worn out and has a hole where there souldnt be a hole will this affect how the motor runs it might be some kind of zinc plate i am not sure

Anthony, It is difficult to follow your posting. Were you able to get the LU off of the '69? It sorta sounds like it...

Anyway, on your shifting issue. I do not know if the two LUs are interchangeable. However, if they are, I recommend you put both the LU and the control into neutral. The LU should "click" into neutral and stay there. Make sure it is in the correct neutral(as there are two neutrals), or your shifting will be backward. Also make sure the black molded plastic shift shaft guide is in the midsection of the motor. It will hold the upper shift shaft in the right place for mating with the lower shift shaft.

the 69 LU is stuck on so i put a whole different leg on which i got off of my blueband what i have done is put the blue band leg on the 69 and and i want to put the blueband LU onto the 69 which i am having troubles with the shifter

I don't think they made a 1150 in 1969, but the first year or two of the 1970s were also a "red band" motors. It would help if you provided the sereal #s for the motors. JR

Re: help with 115hp merc early 70's

i think u are right i have 3 of these motors one of them is redband which i am guessing is the oldest then i also have a blueband and also one which is silver i think it might have been a different coulour but has faded to silver i am planning to use the redband it has the full leg of the blueband on it which i am having trouble with making the gear work

Anthony, I guess I do not know the difference between a lower unit and a "leg".

i have replaced everthing from powerhead down i am just having trouble with making the gear shift work the shifter shaft is lined up but when i turn it at the top of the shaft it does nothing wont make it go back to nuetral

Re: help with 115hp merc early 70's

Before you instaled the mid-section, did you happen to rotate the shift shaft inadvertently? Your best approach at this point would be to turn the shift shaft clockwise from above (disconnect it from the sliding helm lever) until you can find forward gear in the lower unit. You can determine which gear you are in, by having an assistant rotate the prop by hand while you turn the shift shaft slightly.

Once you have the lower unit in forward gear, place your helm controls in forward gear then continue to re-assemble the shift linkage at the powerhead following the normal procedure.

* If your shift linkage cannot be disconnected as it sits now, you may need to pull that powerhead again. Some of the shift linkage designs bolted from below. You should be able to see the nut that holds the shaft arm to the sliding arm on the control side. When you remove the nut, the linkage arms can be separated.

Did you determine the serial numbers for the powerhead, and the serial number for the mid-section you have bolted to it? It would assist. Otherwise, we're just guessing at the configuration.

Good luck.

I think AMD has it, you probably inadvertantly rotated the shift shaft; it's very easy to do, almost does it by itself when you have them seperated.

Re: help with 115hp merc early 70's

thanks AMD i have done what u said i think i got it now i can change through the gears when its in reverse i can turn the prop bothways and it turns over the motor and when its in forward it will turn the motor over 1 way and the other way it clicks is this normal?

YES. And In neutral it free spins. I find it easiest to put them up in neutral - but that's me.

Re: help with 115hp merc early 70's

yes but what i mean is when it is in forward gear i can push the prop around and it will turn the motor over but when i push it bakwars the props clicks and no motor movement then when i put it into reverse i can push the prop around and it will turn the motor over bothways

is this normal????

thanks i musta got it right

Re: help with 115hp merc early 70's

yes

I guess the fact that my YES was in all caps must have thrown him.
Kinda reminds me of that Fed-Ex commercial.

"It makes all the difference."

Wayne, you obviously said YES in the wrong dialect of English - you outta
know better. Don't let it happen again.
