New Drive gears, lower cable, esa unit, now motor stumbles going into gear sometimes

[adchrome]

88 cobra outdrive, just replaced Drive gears,clutch dog, lower cable, esa unit but now the Motor Stumbles sometimes going into fwd gear.....kinda acts like the esa is coming on a bit too long, had it out yesterday for the first time after repairs, taking off it takes a few times putting it in gear before the Motor will start pulling, sometimes stumbles and dies.....I know it might sound like a carb issue but its not,

wont come out of reverse unless i pop it into forward a bit,

is there and adjustment for the esa..?

the shop that did the work wont open back up till Wed, but if its a simple adjustment i can do it myself


Thanks in advance

For one, sounds like the lower shift cable isn't adjusted properly if you have to move it toward forward to get it out of reverse. Ask them if they used both OMC adjustment tools.

To test your stumble, unplug the ESA and see if the stumble goes away. Just be aware that getting it out of gear could be close to impossible so you may have to turn off the engine after your test.

im thinking my esa is coming on a little to far in the fwd position, maybe thats why i have to put it in fwd a little for the esa to kick in...

of course i could be way off here, but how do i check that

Unplug the ESA and see if you get your stumble when going into forward.

no stumble with esa unplugged, yea had to kill motor to get out of gear, if they used the omc cable tool shouldn't the center of bolt to front of the nut be 7 9/16 while in neutral....mine is about 7 3/4 while in neutral, also the top cable with red end is all the way up in the slot

im sure they will tell me they used the omc tools but will doing it this way confirm...I paid alot of money to have this fixed by a so called omc certified shop, gonna raise some hell if

I had to have my lower shift cable replaced when I was at Lake Powell and it completely failed there. I had to readjust it when I got home because they didn't do it correctly.

Another that can happen here is a worn console shifter. If there is excessive slop, they may have adjusted it properly and the slop in the main console controller is killing you. Basically, they can have a lot of "lost motion". When I had my Cobra, I replaced my console shifter and had a huge improvement in shift quality.

Another thing you should do is make sure the shift cable from the console shifter back to the engine is supported/tied along its entire length so it doesn't move. That can help with "lost motion" issues as well.

i read somewhere that its 7 9/16 just read on hastings its 7 5/8 ...which is correct..?

Re: New Drive gears, lower cable, esa unit, now motor stumbles going into gear someti

control don't seem sloppy, seems pretty direct when moving it, cable is tied up the entire length...I checked that earlier

7 - 9/16"

This is of course the measurement with the bellcrank at 90? which you have no idea of unless you pull the drive.

ok, I will probably just take it back and let them adjust it....if its still not right i will tackle it myself

Re: New Drive gears, lower cable, esa unit, now motor stumbles going into gear someti

does it make sense to you from your experience that if its longer than the 7 9/16 that it will stick in reverse, while lever is in neutral...guess what im saying is if i shorten it a turn or 2 do you think that would help

on the esa I think i have a sticky switch , works fine sometimes other times the motor stays in a stumble as i advance it forward,

Re: New Drive gears, lower cable, esa unit, now motor stumbles going into gear someti

Once you advance it forward, the overstroke switch is supposed to stop the stumble.

Been so long since i had the Cobra I couldn't tell you about if its closer toward reverse or closer to forward.

bruce... is there any sites that explain the esa adjustment..? I only have the seloc manual,

after a ton of searching here im reading that the esa should not come on at all going into fwd, and it is, sounds like its to far forward and possibly not coming on from reverse ...make sense..?

I would like to try this first

The ESA should not operate going into gear at all or while shifting when you are on muffs.

yea i know that...im talking about it stumbling going into fwd and have to kick it in fwd a tad to get it out of reverse while on the water

Those are actually two separate issues. You need to get the adjustment figured out getting out of reverse first.

You adjust the lower shift cable with the 2 OMC tools?
You need a factory manual. Forget the Seloc. I am sending you a PM.

Re: New Drive gears, lower cable, esa unit, now motor stumbles going into gear someti

ok,Thanks for the Manual.... think i may have found the problem.....the overstroke switch (one without the long arm) is no where near the cam coming out of reverse its all setup up on the forward motion of the control.....this can't be right can it..? the cam is adjustable in a slot

actually there are 2 cams that are adjustable, neither are even close to the switch coming out of reverse

is the lower cam for reverse....i don't see it in the manual


the interrupter switch (long arm) is in the V at neutral and just in gear in forward and reverse its almost at the top of the V, full throttle both ways its fully on top of the V

could it be when i flick it into fwd just a tad the esa kicks in and lets it out of reverse...?

out of the water from reverse to neutral its fine

Sorry if im looking at this all wrong and complicating things

Re: New Drive gears, lower cable, esa unit, now motor stumbles going into gear someti

When in neutral the switch needs to be in the center of the V. After you shift it needs to be in the center of the V. Basically, it always needs to be in the center of the V except for during your shift out of gear!

Did you use the 2 tools(bellcrank tool and shift cable length tool) to adjust your lower cable? If you didn't, you need to set this first before you mess with the ESA adjustments.
