- Quick vid on converting a 1967 shock system into a fully functioning Hydraulic Trim and Tilty system. Trim and Tilt is a luxury. Who would not want this.... Now you can have it with the correct parts. Additionally, Disable the reverse lock mechanism since hydraulics do not require it. Thanks for your support and the guest speakers/mechanics Bent Rodz & Fat Catz!!! Any questions please leave them in the comments!
As usual AUSTA thanks for sharing your passion with us.
I almost look like a professional. Glad it worked out, nice to learn something new. That engine is a beauty, the buyer will be real happy with that one.👌
Love those old motors. Just put the trim on mine. Not sure how well the old hoses hold up to kinks but we’ll see.
Man you are right on point with this one. As a general rule, these things are going to give a problem with the amount of age on them.
How do you fill the reservoir
Can you do a video on how to bleed the hydraulic lines on this exact trim plz
So happy I found your channel! These videos are going to be a massive help. I am trying to track down the parts necessary to do this upgrade. I have scoured ebay and I can find the brackets, rams and hoses. I can't find a viable pump. Can you help me out?
I have the exact same trim set up as in this video, but my problem is when the motor is raised all the way up you’ll get locked in the up position and will not lower. If I do not raise up it will go up and down all day long, what is this problem?
have the same system already on my boat, but pump took a dump, is there a way to T the hydraulics and use a 2 line pump?
BTW, thnx already, video was very helpful in understanding the workings of system
Yes.
Hi I'd like to do this eventually to my 1964 merc 850, do you know the part numbers or model numbers for the components you installed in this video? Or any suggestions on what I should be looking for? Thanks.
I don't. Mercury changed a lot of part numbers and so did aftermarket vendors.
You're the man. Seriously. Your channel has helped me a ton. I do have a question. I have a 1982ish 80 hp Thunderbolt. Can you give me a general idea of what year trim units will work on it? I'm looking around for info, but it's tough! Thanks again for sharing your knowledge!
@johnzimmerman7798 all dual trim ram systems will work. You just have to have the proper hardware to mount the rams. I have a video on how to convert btw. And thanks for the kind words my friend. Son
Hey Son, so glad I found your videos. I've got all the parts to make this conversion.
Just wondering what fluid you run in your setup?
And have you got a rough wiring diagram? I'm abit lost with what to do with the wires off the ram..
Thanks heaps for the help!
I believe it's 10-40. I can't remember off the top of my head. The trim pump should specify what oil is needed. Son
Any luck with the pump wiring, im completly lost on mine.
Hey man, been trying to find your email. Need some pointers on a 1980 Merc 40. Your vids are the most helpful on RUclips for these older Mercs!

Can I email you about a trim I’m having issues with ?
Great work i have the exact same tilt trim motor that i need to rebuild. Marine shop said it was bad so if they come back with an outrageous price i plan to rebuild in my own. Where can i get rebuild oarts? I cant find a model number to start sourcing the oarts out . Thanks in advance
G'day Son, I have a mercury 1975 65 650 3, it is manual tilt and is very stiff and hard to tilt even if you lift the motor from the propeller; I don't see any lubrication point/grease nipple, it is pivoting between the engine and transom bracket and the pin does not rotate in the motor casting. what do you think is my problem/s? Thank you very much for your help and time
Where do you put hydraulic fluid at on that type of pump, is it the silver big screw that’s on the pump? A friend of mine has that type of hydraulic trim pump with the selenoids on it
Hey son, my double rams arent working when I tested them. I tried with the hoses not connecting to the the cylinders and i have the fluid spraying out of them. What should i look at on the cylinders please?
Spraying out of the hoses or rams?
I have a 1982 50HP Mercury with rams but missing the pump you used. Can’t seem to find the pump and motor on eBay. What am I looking for?
A very difficult pump to find. Son
Hey Son I got a question, Have you ever rebuilt or taken apart the valve body and gear assembly on this style of trim pump in your video? I bought a "new" old stock part number 392-7734 valve body and the gear that the pump motor spins won't spin by hand or with using a little force with pliers..thinking it may be a locked up assembly unless its supposed be like that I don't really know tbh.
No, the assembly is not supposed to be like that. Son
Awesome job, does it matter what trim switch you use with it? Do you need the original or can you use a newer one?
You can use any switch that transfers 12v to each corresponding up and down wire. Son
I have a salvage power trim off an 1150 Mercury. If I add it to my 1973 1150, do I have to drill holes in the transom to mount the cylinders or is it enough to mount the cylinders to the motor? Thanks in advance
I would drill at least the top holes through your transom. I hate drilling holes on boats but it's a necessary evil my friend. Son
Can you do a video of how you made that engine stand out of the Everlast
That would be an interesting video. All I did was remove the top and punching bag, then bolted the wood through the metal on the sides and middle of the everlast stand. Son
hey son. i just bought some shock absorber off ebay but they dont feel like it has any pressure in them. it was easy to push down on them. are they like that or did they sell me a blown shock?
Bad shock. Hydraulic fluid does not compress. Son
I've got that same model tilt and trim pump but all the words are worn off can you help me with what fluid I need and how to refill it and purge all the air out. Also what tool would I need to take the cylinder apart and redo the seals
I use 10-40. Most oils will work. As far disassembly I believe you need a spanner wrench. Son
Hey merc I got this trim set up on a boat I just purchased and was curious on where the relief valve screw is on these. Would like to Be able to drop it or pick it up if anything failed
Short answer is yes. However, the release valves tend to go bad. Son
Do you have any information on the wiring and what goes where percisly, i have an idential pump but its currently stuck fully extended
I do.... by memory. If your outboard is stuck in the fully extended then the issue may not be with the pump but within the cylinders themselves. Wiring is pretty simple. Please verify it's not your trim rams or valve body. Thank you. Son
Hello im new to outboards motor and got a 1978 90hp mercury and im having trouble finding the serial number, could you give me a clue where to find it thanks
Does it matter what hydronic line goes to the trim motor the two small and two slightly bigger lines
It's idiot proof, sorta. Just line up the port side and starboard. You'll be good my friend. Son
Is there any other motor I can use besides this one i cant find it nowhere there sold out everywhere any recommendations
Db electric has pumps for cheap. Son
Hey how you doing. I know this is a old tread. But can you tell me where to fill the motor with fluid.
Tilt motor up. Unscrew cap on the reservoir corner. Should be a flat head. It's the only screw on the corner. Fill, replace screw, then gently let down engine to fill the tilt rams. Son
Hey man, I really appreciate your videos. What do you think a 1979 Mercury 850 85hp in good condition is worth? How much would you ask if selling? Thanks for your help
Depending on compression $800-$1000. Compression has to be there (140psi plus).
So do you think you may post a video in near future on how to troubleshoot hydraulic trim? Mine when I trim motor up with the button on the throttle lever brings motor out past the engine bracket and it’s only supposed to be the trailer button that raises motor all the way out of bracket.?
How do I get ahold of him about my 1976 850 needs power trim
I'm looking to do this to my Mercury. And, Can a guy install a Trim Gauge to this setup???
Yes and yes. The gauge will take some fabrication but can be done. Son
Hey question for you, will these older Mercury's do fine trolling at low speeds?
Where is the release valve on this unit? My trim is stuck in the up position and can't find the release screw. Or is it on the hydrologic motor? Thank you for all your videos.
The trim cylinders could be jammed. Release valve is locked on the bottom of the trim pump. It's the ONLY knob. Son
@@MerCSonL6 under the trim pump, meaning under the RESERVOIR? Or is it between the metal pump and RESERVOIR? I’m having a tough time locating it. I keep looking for a screw but you mentioned knob?
@@danielcaballero3130 the knob should be on the valve body beneath the reservoir. Sounds like yours are missing. Are you sure rams are not locked?
@@MerCSonL6 I found the knob. I kept thinking that wasn’t a knob for some reason. Thank you for the response and I love your Mercury videos! I got a 1976 850 thunderbolt. 👍🏽👍🏽
What is the electrical wire coming off the starboard side cylinder ? I just got a boat and in process of getting it going but no idea what it is for since wire is broken
I need you to be specific. There should be no wires coming off. All should be connected to the internal harness. Son
I have a 1977 merc 1150 and on the right trim theres like a cover and has a wire coming out possibly trim limit switch but cant find anything or replacment unfortunately
@@rubencastillo8977 cut it off. You don't need it. Son
Merc Son I have to pick your brain. On my 85 50Hp four what is the 1/4 inch or so hole next to #1 spark plug and why do I have water coming out of it? I have a good stream out of the pisser. Does not look like there was ever a screw in there. But I see something like its a blind hole. Is it a check valve inside the head cover or something? Nothing in the Selocs manual on what it is
Post your email. I'll contact you so you can send a pic. I would say it's for the psi pressure gauge but that's typically in the middle of the cylinders. Son

What type of oil should use on the hydraulic trim cylinder?
10-40
Ok where do you connect the wires from the trim to the motor
To the battery. Son
What type of oil do you use for hydraulic trim cylinder?
10-40
Hey dude! What trim kit is that? I have a similar motor with the same issue
Just a standard dual ram trim system found on Mercury's before 1984. Son
I have the same set up but my trim only goes up 2 inches
2 inches.....definitely not going to cut it.
Thats the type my 1985 50 takes. Clunky, expensive and hard to find. I am thinking of going with a CMC PT-130
Hi watched all your RUclips videos but I can’t find a video on how to bleed the system on the tilt and trim
I have not done one. It's done by trimming up/down several times then there's a alan screw top/bottom of the rams that you gently unscrew to let out the air. Son
@@MerCSonL6 Thank you for your response I’m just wondering if you can give me any more advice I’m having trouble with the Tilt and trim It is raised up but I cannot get it to go down the motor is working up and down if I press down it moves slightly and if I Press up It moves slightly is there any way I can lower it manually hope you don’t mind me asking you questions Thank you
@@cavemanmicky there's a release valve on the bottom of the trim pump. Turn the knob all the way out. Son
@@MerCSonL6 I have screwed the knob all the way out and it hasn’t Moved
@@cavemanmicky sounds like you have a locked ram. You will need to find out which one by unscrewing the Hydraulic hoses. Son
Where can I find this model pump?
4 line hydraulic…
Ebay. Son
Where about do you live? Looking to see if you're near enough to me to potentially work on my 83' 115hp.

Wich hoses goes where is my thing I cant seem to figure out
The hoses are 2 sizes. Line 2 hoses to trim ram and the other ends to the bottom of the pump. There are 4 separate connections on the bottom but they are separated into 2 each. Connect the 2 hose to the corresponding inlets. Repeat steps for second set of hoses. Son
How does one get this done? I would be happy to pay you to make me one for my merc
You need the dual trim rams and a trim pump. Modification is easy. Whats your zipcode? Son
Hey man I want to do this to my 1975 650 thunderbolt, what should I search on eBay for?
I have an 1985 Mercury 115 manual tilt. Will this work on it. I have access to a same model year 115 mercury with blown powerhead that has power tilt and trim and was told my powerhead would have to go on the power trim and tilt mid section. If all the power parts are in good shape can they easily go on my engine?
Yea, it's really ambiguous when you get to the newer carbs. Seems like every kit fits but as different part numbers. Last 96 I worked on I looked at the carbs the gaskets and guessed.... I was correct thankfully. They need to make carb kits easier to understand but due to different manufacturers that's impossible because they all make up there own part numbers unfortunately. Good luck! Son
How do you fill those hydraulic lines?
Tilt engine in the up position. Fill reservoir. Gently let down the engine. Done.
I have a question, I have the same power trim system I'm installing right now. Where do I ground the black wire on the pump? I can't seem to find where it goes
Specifically where does the big black ground wire from the battery connect to the pump? It was disconnected when I got it and I don't know where to attach it. Thank you!
It grounds directly to the battery. Son
Where put Fluid in on a trim pump
Screw on the base. Should flat head. Only screw there. Son
@@MerCSonL6 it’s on the trim unit correct??
@@LS-ml8ll yup, on top of the reservoir. Son
@@MerCSonL6 thank you for your reply!!
Finally got my 1980 Mercury 90 trim to work!! Thanks again for your help!
What type of oil is use for cylinder?
10-40
I just bought a 1989 Black max v6 mercury the decals say it's. A 175hp but the guy said its. A 150hp how can I find out what is the actual motor that I have. As I am new to it boards.
Thank you.
Looked up the serial number. It should be located starboard side right beneath the powerhead. Son
What parts did you use?
What "part" are you referring?
What’s the part number
I don't know parts numbers. Mercury changed them each decade. Son
Got the same trim set up for 70-83. My problem is is will only trim for around 3 seconds before it quits. Felt them motor and it is extremely hot likes it struggling. Anyone know what's wrong? maybe the valve body?
Tllt engine all the way up and check the reservoir. Should be full. Motor could be at fault as well. Son
@@MerCSonL6 Thank you very much for replying
@@Just1nFR you're welcome
Interested in this motor.....LMK

There's a few interested. Things a beast!
where are you located?

@merCSon L6 I have a 72 thunderbolt without power trim and finding one is becoming a project. Which power trims can conform to this motor?
Any trim system from 1970s thru 1983. Son
Hey son can you give me a call by chance ?
Email?
Camera movement.. just puked
Great. If that's least of your worries you're in great shape I'm sharing my knowledge for free.... so if you can't handle free.... please by all means produce your own videos. Son
