1966 Starflite 100 with electric shift (now running well, for those of you who've made suggestions for me in the past).

About 3/4 throttle and it slipped out of gear. Wouldn't go forward or reverse. Opened control housing and the three wires to the shifter buttons were warm. Not hot, just warm. Fiddled with the knife connectors inside the motor housing that connect to the solenoid and it then shifted into reverse but not forward.

I'm about to crack it open and look at the solenoid, but if that's not it I'll be looking for suggestions.

Update: Solenoid leads to ground read 0.6 ohms and there is continuity between the two solenoid leads, I assume that means bad things for the solenoid. Next question: How do I get it out?

First of all they are NOT solenoids down in there.

There are 2 electromagnets that pull / attract a spring over which then wraps around the drum.

Do both read the same OHMS when you test with one meter lead on the coil wire and the other meter lead on the case/ground ????????

Testing to both leads means nothing.

Post results.

I am thinking the tab broke off the forward spring

That started with the hydro-electric shift in 68 on the 3 cylinder 55 HP. The first V-4 with hydro-electric was 1969 and lasted till 1972. All electric shift units are a thing of beauty , well engineered and reliable. Check this box to be notified of replies to this topic. Note: BBcode and smileys are still usable.

I agree.The only trouble I've ever had with an electric shift was the forward wire going down to the gear case breaking in two after 40 years service and I still got back to dock(reverse wire didn't break)

The lower unit is off the motor, it was leaking water so I had to get it off anyway. Also the blue and green wires are reversed inside the lower unit (forgot about that until now, but at the knife connectors the colors are reversed to make the shift buttons do what they say).

That said...

Now a reading on either wire from the lower unit reads about 6.3 ohms, a change from an hour ago. Jiggling the wires around did not change the reading.

Connecting power to either wire resulted in a nice little spark of about the same intensity, but only the BLUE wire produced a satisfying "click" sound from the gear case.

Your OHM readings are good, they should be the same. Check this box to be notified of replies to this topic. Note: BBcode and smileys are still usable.

On ----shop.evinrude.com

They are listed as not available new for the 68 model ( same lower unit )

NO SPECIAL TOOLS REQUIRED TO REPLACE A BROKEN SPRING.

Well maybe a slide hammer with 1/4-28NF thread.

You have tested both forward and reverse engagement ( 12 volts applied )with the lower unit off.

Should drag one way when turning the prop and engage after 1/4 turn going the other way.

Forward spring is the one furthest from the prop, right? Reverse spring is fine (assuming it's closest to the prop).

Forward spring engages under no load: I can manually turn the drive shaft and it will engage the prop shaft when current is applied.

After work today I need to test it further to see if it slips when resistance is applied, but as of now it appears to be working normally.

Springs are on ebay for about $200. Yikes.

The shift wires don't look to be in the best condition, thinking it would pay to replace those. Is there a trick to that? Oil pump and drive shaft might be coming out tonight, but only if necessary.

Drive shaft has to come out in order to remove the forward clutch spring / hub / gear assembly. Electromagnet stays in the housing and may not have to be removed ( except for wiring repairs ) Pretty simple stuff really !! Check this box to be notified of replies to this topic.

Prop shaft does not slip vs. the drive shaft when forward magnet is energized. I could feel the spring tension but it did not slip.

However, the wire to the forward magnet has continuity to ground, even though it still seems to work. So I'm thinking it's a wire. Good news it's a lot cheaper, bad news it looks like a PITA.

But this weekend is supposed to be cold an rainy anyway so I'll need a good project. And I can inspect the spring while it's out.
