I have Evinrude 6ph, 1968? I have recently been having a problem with it going into gear. With the motor off it goes into gear most the time, if it doesnt I have to move the prop a lil to get it to go into gear. When the motor is running its even harder!! After drifting for 20mins on a lake I finally got it to go into gear with the trottle down pretty low. When I was drifting it was kinda in gear but not fully, it would move the prop barly enought to steer the boat but not enough to steer back into the wind. What is wrong??

By the way Merry X-MASS!!!!!!:)

Re: Not going into gear.

i brownhunter. There are a couple things you might want to check. the first would be the shift rod connection. make sure there isn't any slop in it. you may also want to open up the gear case to check the gears and clutch dog. here's a link to an exploded parts diagram of your motor. just click on your model number. it will give you an idea of how everything goes together. happy boxing day.

Re: Not going into gear.


I don't have any personal experience with this motor, but there are two posibilities. One is there is a problem with linkage, the other is a problem in the gearcase. Dismantling the gearcase is an expensive job, the parts are expensive, and it isn't really a Jonny boatowner job.
Look closely at the linkage. Shift it in and out while studying the moving parts to see if there's any place the linkage could be causing the problem. Then check back.

Re: Not going into gear.

If it revs up in gear like you pushed the clutch in on a car, and not 'clunking', it may be a spun prop hub. Search this forum and you'll find lots of info..

Re: Not going into gear.

Sorry mmike, but this gearcase is a split one horizontally down the middle. Easy to pop off & look inside.

About all outboard motors the clutch dogs have to be aligned for the gears to engage so shifting it when not running you will need to pull the starter rope or rotate the prop. When the motor is running, it should slide right in.

There is a shift rod detent spring inside the gearcase. Maybe it has shifted out of position. Or worse the gearbox may have had a leak & water has entered resulting in rusted parts. Pull the bottom of the gearcase off & look.

Go to my website http://www.sschapterpsa.com/ramblings/OMC_6hp.htm as here I show the gearcase apart.

Re: Not going into gear.

Thanks guys for the links!!! I never had to pull the rope to get into gear before with out it running. If i remember correctly it would always just go into gear when I moved the handle with out having to move the prop.

Re: Not going into gear.

Ok I checked the linkage seemed good, then unscrwed it and used plires to move gear rod on lower unit to put in forward and reverse. its a pain to unscrew it from the gear rods, they only give you so much room! ugh! seem to be no problems when I do with pilers. now its back together again and half the time it doesnt go forward or reverse with having to move the prop. the lever wont go all the way back or forward unless the prop is moved.
now what ????

Re: Not going into gear.

Here is a video. Motor is on its side, but same things happen with its upright. Just now in the trashcan When the motor was running I could pull the shift lever all the way back to reverse and all the way forward for forward lol. But it was not going all the way into gear, just enough to rotate the prop. i throttle up its not doing what it should be, but when its running at low rpms the prop moves more. just like when I was on the lake. What is wrong!!!

Re: Not going into gear.

that's normal...have you checked for a partially sheared or bent drive pin?...marine engine dot com has diagrams of your gearcase <easy to navigate site by year, hp., model no.>..or as kbait suggest, the prophub may be spun...plenty of posts using the search feature on spun hubs

Re: Not going into gear.

Ya that is completely normal an how it is suppose to work.

It isn't like a car with a clutch where you put it in gear and it is ready to go.

How a lower unit works: there are 3 gears in the lower, pinion, forward and reverse aranged in a "U" shape with the pinion on top the gears are free to move on the shaft and are always turning if the engine is running, between the gears is a clutchdog that is attached to the shifter and slides back and forth and is pinned to the prop shaft.

The clutch dog has "ears" on that match up to detents in the gears, as it slides forward it engages the spinning gear and goes into gear.

If the engine isn't running and the gears aren't spinning the detents may not line up which is why you have to turn the prop slightly to get it to engage, completely normal and how it was designed to work.

I suspect that you have a worn clucthdog with rounded ear and it no longer engages the gears, pull the lower apart an check them, everyhitng shoudl have a nice square edge on it.

Re: Not going into gear.

When you're out on the lake. if the shift lever advances all the way forward but the boat doesn't seem to move, or only moves at low speed, you either have a spun prop hub or a sheared drive pin. If, on the other hand, the shift lever doesn't advance fully into forward or reverse, then it is a linkage problem, either loose or worn, or a problem with the shift yoke which moves the clutch dog.

While in gear it does go all the way forwards and backwards in the lake or the bucket, it does also barly move the prop and the pins/keys are fine. I am looking at the diagram, I dont see anything called a "prop hub" on the list of parts. is there another name for it?

Also I am not having any luck removing the screws so I can look inside the lower units gears, the flat head screw driver seems to be stripping the screws!! :-(

Re: Not going into gear.



I did find this broken part, the picture is blurry sorry, but its dead center. is that my problem? I thought the prop spun from the pin. Is this broken part the hub? which looks like a notch that goes the back of the prop? or does the prop spin because of the notch and the pin?

I still cannot remove the screws!!!! :-(

Re: Not going into gear.

or is the hub the rubber inside the prop?





When i have the motor in gear i turn the prop by hand and it spins but the gear rod does not. like the prop is spinning around the rubber. I cannot find any place that sells new prop hubs, does this mean I need a new prop? I have given up on removing those screws I dont want to strip them. Might have bore them out if needed. :-(

Re: Not going into gear.

Wow! So the prop just slips off the rubber hub as in the pic? That's your problem. That hub should be tightly press fitted into the prop and the prop shouldn't spin on the hub. You need to have the prop re-hubbed. A Johnnyrude dealer can do the job or have it done. Probably cost you $40 50.

lol.....the prop came off the hub? lucky that it even moved the boat! as mentioned, get it re hubed, or find a second hand prop.

Re: Not going into gear.

Not really. It did take some work to get it out with pushing it out with a screw driver, buts not super hard nor easy to do so. And it takes a hammer to pound it back in. Like I said, once I put the motor in gear the prop will turn before the gear rod and flywheel will. it spins around the rubber if i hold the prop by hand and it takes some pressure to stop it from spinning. if i turn the fly wheel it spins the prop. though I really dont know if water puts enough pressure on the prop for it to not spin like its not in gear. so i am still at a loss!

so the rubber is a prop hub????!!

re-hubbing sounds alot cheaper then getting a new prop!! cant find any used ones.

and i think I am screwed from getting the lower gear case off as the screws wont come lose!!:-(

Re: Not going into gear.

Wow. That rubber looks in good shape although you shouldn't have really gotten to that state so easy! It definitely needs to be re hubbed. Old used props are common. Look around. Check the aomci.org website and maybe put an add out for one. Check the used places as mentioned in the top secret file at the top of this forum.
