omc 4.3 cobra out drive

[tgmurphy]

I have a mechanic that can't get it right. He has replaced gimble bearing, waterpump bellows and has had the out drive on and off 6 times over the past 12 weeks because when you select foward it goes foward. then you select reverse and it goes reverse. when you go to take it out of reverse it won't come out of reverse untill the engine is turned off and nutral is selected. I have disconnected the out drive cable and tryed selecting but the same thing happens. HELP ME PLEASE after 12 weeks i am starting to loose my cool.

Sounds like you've replaced most of the important stuff, now you need have the lower shift cable replaced, adjustment will not fix it.

Is the shift interupter working? If you have a engine manual you can locate the arm on the carburetor and push it down to activate it, if the engine doesn't stumble you have a problem and it will be near impossible to get out of gear. If it is working you might have the idle to high.

Its the ESA. I am guessing this only happens when you are in the water and not when you are on muffs right?

There is a microswitch that gets depressed when you shift out of gear. When this occurs the EAS stumbles the engine.

Has anyone installed an electronic ignition in the distributor to replace points? If so, these are incompatible with the OMC ESA without some modifications.

This is correct, I relpaced my points with a Pertonix unit and had to do the modification mentioned. No big deal, a couple of resistors and diodes and you good to go.
