Thanks Mike for the informational video. I also had a bear of a time reconnecting the lower unit. I figured out a way to do it without messing with the cables. I held my finger on the female spline up in the upper unit then had my wife shift it back and forth until I could tell just when it went from neutral to forward. I had the lower unit shifted into forward and used the bungy cord trick to hold it all tight. Then while lifting up on it with everything lined up I had my wife shift it slowly to forward. It went right in and everything worked.. took two people though. Thanks again..
Excellent video! That clicking noise is what my buddy’s lower unit is doing when we put it in forward gear. We don’t have any clicking are slippage in reverse just in forward…. You didn’t say if theirs any adjustment in the connection point at the motor but I’m going to look at it before I drop the lower unit…… Thank you!
Thank you for the tips brother. I was in the same pickle after changing my impeller. Mine is even older but similar. I have a 1965 90hp Mercury tower of power.
Awesome video mike!! I know nothing about a boat..but have been an auto mechanic for 30 yrs...thanx for the vid!..I. learning how to work on a boat thanx to you!! Lol
that cam part is to throw the lower unit into neutral if the motor kicks up. it also work with the tilt bracket to lock the tilt pin when in reverse. it is easy to install. if the motor is tilted. then put the cam in neutral. and place the cam part so that the push rod is sitting at the bottom of the slanted section. so the highest point would be to the left. when in reverse. the push rod is sitting on the highest point. make sure the lower unit is in neutral !!!!!!!! so that when you lower the motor it does not put force or break the cam part.
Hey Paul got a question a buddy 9f mine replaced the water pump and must have moved that gear and when he tried to put it back together he broke something. Now the shift shaft spins freely. What do you think he broke and how hard would it be to fix
@@ClearwaterAngus are you sure he broke something? if the shift shaft is spun when the lower unit is off the outboard, it will have a free spinning effect like what you said. try use a pliers and spin it back into place. you will hear and feel it click into gear. after it goes back into gear continue in the same direction and you will find neutral and the other gear. reverse is to one side and forward to the other neutral is in the middle. when putting back the lower unit on. put the lower unit in neutral and make sure the shifter is position in the neutral position.
I appreciate your sharing this video. I too lifted of that cam not realizing the importance of its settings. I did the same thing as you started worrying about the seriousness of what i did. I am thankful for you sharing this hard to find and figure out information. So thank you very much. After i study your videos in much more detail, i will try to fix her right hopefully within the first attempt. I know i have learnef from my amateur mistake. I wont do that again.
The gear box has 3 positions Forward, center neutral and reverse When you rotate the splined gear shaft out of the middle position it will lock the prop in either forward or reverse. Not sure right now which way the engine turns ( clock wise but check ! )
Thanks! I looked in the manual for this procedure as well to no avail. Crazy they left it out of the manual when your supposed to service thevwater pump every year. I picked up a 35 hp for $100 and needed to baseline the water pump..
That piece doesn't operate and gears or lower unit linkage. It only controls the latch on the back of the motor that keeps the motor from popping up when in reverse. However I can see how it would cause a bind effect if not positioned correctly. It's all part of the midsection of the motor
I had no idea what that part was called until I put it on the counter of the Mercury parts desk. They called it A SHIFTER CAM SELECTOR Stupid me believing them !!!!!!
The position of the splined shaft Mike is moving with paper towels and vise grips moves the gears in the transmission between fwd, neutral and reverse. The cam operates a rod, that locks the motor to the transom in reverse only. To see this, with this lower unit removed, go push the rod that rides on this cam up and down and note that it operates a set of "claws" that grab a rod on the motor to keep the motor from popping out of the water when you're in reverse.
Use an internal Torx E-12 socket with a rachet and apply some pressure CCW while turning the propeller shaft to get it into neutral - turns both ways with out resistant.
@@kyleluzier2163 other videos shows them clicking the prop saying that its good thing, this guy says its a bad thing im so confused been trying to get my lower unit back in after a water pump change and now its all jacked up trying to follow these videos
Talking to Joe over at Haney Marine he said just turn the flywheel and it turn the female receiving spline, it will pop in but be careful not to turn the prop
Thanks Mike. So, my other questions, when engaging the lower unit with the upper unit. The cables should be disconnected (note that this is a replacement engine that was not fitted in this boat before & will require readjustments) and with the cables disconnected the cable connector gear position should be in the backward/ reverse position, correct?? By gently pulling on the pull start or rocking the flywheel I can see that the male/ female splined gear shaft can mate up. To check if I understand your instructions correctly with the lower unit facing forward and the prop located in the aft position. Turn the lower gear selector splines all the way anti clockwise i.e. to port. Now rotate carefully clockwise gently to port unit it clicks over (becomes stiff) & locked. If one continues to rotate the lower selector just slightly it cams over again and then has heaps of free play/ movement all the way until it stops about a ¾ of a turn. Stating over from above the second or locked position turning from port to starboard is the one to be at before it cams over, correct??? Now is the time to fit the selector thingy so that the sloped angle is just starting to slope upward to the right/ starboard side of the “”forward centre”” position, correct? Sorry to be long winded over it, thanks.
Lol all that is, is the reverse lock, and it's super easy to mark it with a paint pen or sharpie, or just put a little scratch in it, turning the prop etc etc doesn't affect that whatsoever lol, you just pop it back on where it goes, it slides on in a static position..
So i dropped my 75 mariner in forward gear , put the lower unit back on , it’s stuck in forward and will not go in neutral. Im not sure what you were trying to say to fix this. Please explain THanks
Pretty sadistic of you not to have emailed me with this superior knowledge before I pulled the cam , but then I wouldn't have gotten 36,000 views and helped all the other people you ignored !!! I guess some people only care about themselves ,,,,,, I think you missed my opening statement.
@@mikepettipas690 You didn't have to do ANY of that lol. You literally leave your boat in neutral, drop the lower, rebuild whatever you need to do in the lower, drop your reverse lock back in the same position you took it off, slide your lower back in, and you are done..
@@darksidedemi My God, lol did you NOT hear my opening statement lol ? The entire video is about NOT remembering the same position lol, No factory spline key way lol, and what happens when it's NOT put back in the CORRECT POSITION LOL !!??
I just put water impeller in, and can switch into gears but prop does t look like its changing direction when put into reverse on 115 mariner 1993 i'm going to give it a try. thanks!
@Mike Pettipas I have watched all three of your videos. But still have a problem to get it right. I’m working on a 1974 Mercury. I believe my big miss-understanding issue is the “exact location/ rotation of the gearbox grooved shaft” before fitting the reverse locker or whatever it called. That input shaft can be rotated both ways clockwise & anti clock which is confusing the hell out of me. I'm looking for an easy step by step solution. Where is the sweet/ or correct spot? Thanks in advance.
Ugh working on this for far too long. The reverse stop that your positioning. Does the spring loaded pin (next to the female spline) need to be pressed in for reverse, or forward? Your positioning shows forward is pressed in (tallest flat point on the reverse stop), but I thought it was opposite?
I have a 2005 mercury 60hp and can't get it to come out of forward at front throttle arm, almost goes into neutral but not going to force it, guess I have something out of line, even with lower unit off the front arm doesn't come out of forward
very informative my cams are a little different but my problem is the spline shaft you are turning with the vice grip . On mine the shaft will turn by hand at least 180 degrees before meeting resistance and clicking into a gear or neutral . What do you think my problem is and or what is borken / stripped etc., thank you for any comments
Check out Dangar Marine and his bottom end video. The selector shaft goes down to a clutch fork and moves the dogs forward , neutral center or reverse. You might have broken a finger on your fork. Check out the video and prepare to disassembled. !
@@mikepettipas690 ok, i guess i should have figured something broke i just hate the thought of taking things apart and trying to get them back together. All i wanted to do was ride in a boat a little lol lol
What is that piece called he is putting on the male shifter, my motor doesn't even have one of those on it, what is it and what is its purpose other than alignment?
I have same motor and notice your pick up tube just goes down into impeller housing. Isnt there a sleeve or grommet that goes in there? Mine is not picking up the water and I wonder if tube has slid up too high and needs to be pulled down. It does have a round rubber ring inside the pump housing. Does that make sense?
Pull the lower unit. Blow water or connect a garden hose to the copper tube with duck tape and water should shoot out of the piss hole and exhaust. If not you probably don't have the copper tube connected correctly or some kind of abstruction in your water pump
Mike, I've watched your Video so many time's i've almost memorized it, but I can not for the life of me figure out where the shifter arm needs to be, I've been told that the RAIL where the Cable Connector rides on is such, Forward Neutral Reverse. So if the Cable Connector is in the Middle it's Neutral and if in the Forward ( away from the prop ) it's in Forward. So then with this being said, If I put the Shifter Spline in the Forward Position, How should the Reverse Cam be oriented.. My thinking is Flat Spot at 6 oclock ( away from prop ) Edge oppsite of the Slope is at 7 oclock, Prop LOCKED in with no Clicking, Cables are disconnected, Lower unit is still in Forward position, with cable still disconnected push Control Lever all the way Forward, with Barrels removed Adjust Cable Connector to Connect to Shifter Connector ( the part that rides on the rail ) and if the creek don't rise and the good Lord is willing Everything should work as designed.. But as I say all this, with the Shifter in Forward, How is the Reverse Cam oriented..
@@mikepettipas690 I have the Service Manual, as you state, it doesn't really go into the Reverse Lock Cam Positioning. I think I just need to Find Reverse, Position the Cam Flat Spot under the Lock Plunger, then Adjust the Cable so that it can't go any further in Reverse causing the Plunger to Drop off the Deep End..
@@mikepettipas690 already found out what I needed elsewhere cuz your video sucked and you never explained what it was what it was for etc. So make better more informative videos if you don't want people frustrated with you.

That part is called a reverse lock cam. Shift lower unit into neutral. Place high point of cam facing forward.
It has to be at the very top of the ramp facing forward.
Use an internal Torx E-12 socket with a rachet and apply some pressure CCW while turning the propeller shaft to get it into neutral - turns both ways with out resistant.
