push button shift

[KIRCHNER]

Remenber OMC electric shift? 1969 had a 90v4with push button shift. was part of the control box. w kinda a bullet l/u. it worked great, no levers, no knobs, it used a electrified coil spring that grabbed a knirled shaft when the button was pushed, sort of a centrifical clutch. ahead of its time for sure.

Push button cars, too... around the same time.

My boss is one of the few people left on this coast who will still work on that junk. I refuse to learn. Most people who still own them can't even afford to change their oil. Cant even count how many electric shift stringer drives are here cluttering up the shop.

Have to pull the drive and take apart the upper unit just to do a damn water impeller. Wore out shafts that they don't make anymore...

When your shift switch in the control box starts failing it shifts into reverse and forward at the same time and blows the shift actuator to shreds...

yes i remember them there was 2 difference systems used ther later ones were pretty good i used one for years worked on a few in my shop overall not much trouble with them

Mine worked great, summer after summer. i ran it hard 6800.was a great unit, fo 54yr ago!

My Dad had a 50 on a 14' McKee Craft. (Like a Boston Whaler). It was called Evinrude Selectric. It had 3 buttons behind the throttle lever. They were supposed to be undependable, but we never had a problem.

Wasn't there some kind of spring that became obsolete without the unit would only stay in forward? I had a 1963 evinrude 75 with the electric shift.

I think you're off a year or two,69 had a blunt electric over hydraulic gearcase...push button shift.In 68 the 85 has a bullet full mechanical shift,while the 100 had a full electric shift like you described,with a gearcase blunt as a softball.Some,80 and 90 hp 66 and 67 I think has pointy full electric units...worked on them all,Chris

heres the deal. there were 2 cases,both had the streamline case. the mech shift was shorter . i forgot the gear ratio,1 ran a 12x19 2 blade @60mph potato chip. we pulled off the long bullet case,for the short bullet mech, no gain. the x115 CASE, was sweet, low water intakes, little cast wings on the bullet, there was 1 in our showroom, it was the besr thing i ever seen, i was a kid.. wheh the boss was away, we pull the cowl n drool

the 1968 units had a spring that held it in foward gear they called it get home mod

[donmac]

the spring had a formed 90 end which locked it in place, high idle shifting would break that ear off and leave you with no propulsion! power 1 coil for reverse and both coils for neutral is how I recall they worked! type c oil required for gear oil and they were very limited on horsepower that could be applied or the spring would break the end off!

I think we're mixing the two types of electric controled shifts.The full electric had the spring wound around a drum attached to each gear,energizing a magnet caused the spring to wind up and bind to the drum...your in gear.OMC stringer drives,early,and some outboards used this,and there was a forward wire and a reverse wire,if they shorted to each other both gears engage,locked the unit, and usually broke the tip of the driveshaft off.
The next unit that had 2 electric solenoids in the front of the gearcase where modern shift rods go was the electric over hydraulic used 68-72.The solenoids closed valves that routed pressurized oil,from a pump in front of the forward gear into the hollow propshaft,the first pushed the clutch dog th neutral,the second added pushed to reverse.This unit started in gear for a second or two...untill oil pressure built up to push to neutral,Chris

chris is correct

[KIRCHNER]

yes ccm your right on, mine was the coil around the drum model
