This video is a quick one on how to remove your lower unit from a 1976 Mercury 1150 Tower of Power. Keep watching more to come! - Auta a dopravní prostředky
I just want to personally thank you for this series. They’ve helped me over the last few years and I never had a chance to say 🙏!!
No worries, I was graced with guidance from a merc guru. Best I can do is share the knowledge. Good luck, and happy tinkering!
Try to find a 4 by 8 piece of carpet and bond that to a piece of thin plywood. It makes it a load nicer when working on grass.
The hole to access the bolt for the trim tab is only 3/8" diameter on My 1969 110 hp. Barley can fit a screwdriver in ther. Don't know how you got a 1/2" socket extension down ther.
@ Jordann Haste, you can buy parts from ebay no problem.
Love your videos man. I just purchased a boat with a late 70's 115 merc tower same as yours. I went to replace the impeller, and when I removed the lower unit, the "shift shaft" spline stayed the upper unit of the engine. I tried re installing the lower unit many times and I can't get it to shift now, it just stays in forward gear. Any suggestions?
Eric Ryan did u ever fix it? I have the same issue
Ive got my 1985 90hp running with your help but I have water in the lower unit. Do you have any videos on prop and seal replacement?
Not currently. I have a lower that I need to rebuild and will document when I do.
Gear needs to be neutral or forward before removing?
What did you pay for the new power head?
I am having problems putting the lower unit back on my mercury 1978 90 hp outboard! What gear do i put the lower unit in?
What placement do I use on the gear selector at the linkage at bottom cowl? I have a manual but it's very confusing!
Thank You

Neutral and Neutral. If you are having getting it back up into the hole, you may need to rotate the flywheel a bit to mesh the gears on the top of the shaft. How far off is it from going all the way back in?
i have a 76 85 hp mercury that the lower unit cracked on, how hard is it to just remove the guts and put on a another housing?
Haven't cracked one open yet. I have one I need to do, but you do need a few special tools. Like the retaining nut wrench..
Hey, I have the same motor and am having trouble getting the lower unit on with proper shift alignment. It shifts fine with the lower unit loosly bolted on but as soon as i tighten it down those 2 rubber things on lower unit shift shaft get pushed together and lock things up. Do you have a picture with proper orientation of those 2 rubber things? Any help would be awesome.
zac smith at 8:42 your holding the top "rubber thing" and move it to the mid section. Are you in neutral or forward for this video?
zac smith I am in Neutral. What gear were you in when you disassembled.
i got it figured out I had the top rubber thing upside down and after I figured that out it went back together easily. Just want to say thanks your videos have been awesome getting my outboard going again. Thanks for the response too.
zac smith Glad it was something simple. Won't make that mistake again!!! Cheers!
at 1:10 in the vid you remove that skeg looking thing,I cant make out what you called it.I need to order one
Zinc anode/steering tab
This is probably a dead thread. But hopefully you can answer. I have this same motor. I just bought it. The bearing carrier is cracked. Where do you buy your parts? I can't find one anywhere.
Absolutely not dead. LOL
try ishopmarine or oldmercs If you don't see it there, use the parts diagrams to find the factory part number and search on Ebay. Works like a charm.
Thanks for the reply! I found the parts finally lol. Hey man, I've also got a dumb question. But I'm new to boats... Are these engines two stroke or four stroke??
2 stroke bud. You have to add oil to the gas. 2 stroke oil.
cturboaddict that's what I was thinking beings as there's no oil cap. Sweet. Thanks.
cturboaddict I've got all sorts of probably dumb questions to ask. So sorry in advance. I just can't seem to find the information I need online.
How big of a fuel tank do I need? Does it have to be a certain shape or brand?
is there supposed to be a gasket between the lower unit and upper?
nope
to start to removed needs put the shift in gear or leave in neutral ?
I keep mine in neutral
I dropped my lower unit to replace my water pump but when I did a piece fell down inside that looks like the top part of the drive shaft. Now I can't get it aligned to put the lower unit back on. It looks like an extention to the drive shaft. Any ideas?
Thanks
Like a bearing? Do you have a photo of it?
I figured it out, it's an extender to my drive shaft. apparently I have a longer lower unit so it has an extender. It falls off when you take the lower unit out. I'm going to have to take it to get serviced. Out of my reach. Thanks for responding.
Willa Hillchrising so, you have the spacer on your lower?
Yes, I guess it's a spacer. One for the drive shaft, and one for the water tube. Not an easy fix right? Will I have to take the middle u bit off?
I have a 1975 1500 Mercury 150 s/l 6. Got the motor running just fine other then the idle bring a bit high. My deal is the remote control box. I have to use the high idle bar and the throttle to get the prop to move forward and the same in rev. Don't really know what's up with that.
Sounds like your shift linkage may need adjustment. Search my username and shift linkage. I think I did a video on it. If now, theres sources on the web.
@@cturboaddict okay cool thank you for replying bro.
@@cturboaddict oh did you ever get your running right?
@@jamesmiklebost7127 yup.
hi, I'm having trouble getting the lower unit off, I've removed every fixing but the prop seems stuck. any ideas?
+Stuart Goodwin Give it a swift Kick on the tailpiece. It'll go. It's probably just stuck a lil bit.
+Stuart Goodwin Be sure to have it in Neutral
Nice 1 mate, it's off 👍👍
+Stuart Goodwin awesome
Does anyone know how to lower or take off the bottom cowling to get to the bolts on the bottom of the cylinder block? I have the cowling completely loose but am failing to see how to get access to the bottom bolts. Do you have to take the whole bottom half of the motor off? Thanks
Its in one of my disassembly vids
Thanks. I have been trying to find it. What is the title?
@@patrickhenry2324 dont recall off the top of my head. But you can unbolt it. Itll drop down a bit. To fullybremove it, you have to pull the powerhead
Would that be the same water pump on a 1985 mercury 115hp
Yes
@@cturboaddict thank you so much!!
hey my boat rpm is high on my motor how can i adjust throttle cable can i do that or timing off
How high is too high? Are you checking this while in the water?
yes my motor is mercury 1000 my motor is on tbdc and it idling very high i can move distributor with my hand to adjust the idle rpm and there is no selling to it how can i ajdust the lower distributor unit to counterclockwise about 1 inch can i adjust the throttle cable ? and i did everything as u did in ur link&sys video all the adjustment works accept the last idle adjustment scew on 0 top dead center it would not click for spark ?thank you
How can we contact you for some info about this engine?
Right here....
@@cturboaddict how do you change the engine oil on this engine? thank you
@@christopherbarakat2013 its a 2 stroke bud. There isn't any engine oil you change. You add it to the fuel.
@@cturboaddict your right😆 thank you very much
I lost the part you call shifter at 8:12 into this video. What is it really called? Left it in the upper section that you moved it to. Lost it and now really struggling to find and order it. Love the videos. Helped tremendously.
Let me find the correct part name.
greg simcakoski 52887 GUIDE, PUSH ROD - REVERSE LOCKING
Not available for purchase, but there is one on Ebay for $13 with free shipping right now.
greg simcakoski www.ebay.com/itm/52887-Mercury-Outboard-Push-Rod-Reverse-Lock-Guide-80-90-115-125-150-/131161836453?pt=Boat_Parts_Accessories_Gear&hash=item1e89dacba5&vxp=mtr
***** Thank you very much! BTW how is that motor running? I am going through the same rebuild, but stopped short (once again) when putting back the lower unit. Kind of wondering if this old beast is really worth all the work.
greg simcakoski If you watch thru my videos she's running great. Bested 45mph with myself and my large pal in my 18' sidewinder with a full load. Got the tilt/trim working right, so I'm hoping a bit more trim will give me a few more mph. Haven't gotten out yet this year.
Hi, I am wanting to remove the whole steering (Pivot Assembly) it has seized from standing so long. My question is how do you remove the gear selector shaft that runs up the centre in order to remove the steering assembly? Is it a big job to remove the power head? Thanks
Unbolt from main shift shaft. Disconnect cables. If it's seized, may be easier to find a different mid section to replace tho
***** Hi..thanks...the gear selector arm has a pin going through it and no ways can you use a punch to remove the pin and slide the selector shaft out the bottom. Also no way can you slide it out the top..due to carbs and inlet manifold. Would removing the actual power head be the only option?
Roy Abbott what year is it bud?
It is a 1974..according to the serial number.
Roy Abbott pull powerhead, should slide straight up. I have a video on powerhead removal on my channel. Easy job
i have done impeller and complete water pump, but i am having trouble installing lower unit, does not want to go all the way in. i have looked for videos, but have not found any on installing lower unit.
+WeThePeople shift cap, water tube, and exhaust all match up, but will not go all the way in. any suggestions?
+WeThePeople Sometimes a common issue.... Try rotating the flywheel slightly then pushing it back in there. Sometimes the driveshaft and crank splines don't line up properly. How far away is it from going all the way back up?
+cturboaddict 1/2 to 3/4in from going all the way back in
+WeThePeople try rotating the flywheel before putting it back up and let me know. typically I can get them about the same distance before I have to use the bolts to get it fully tight
+cturboaddict i can start the nuts but i do not want to force it
