Mercury tilt and trim fix

[@TheChrisCCole]

Thanks for posting this. I busted the head off my trim release screw too. What I did differently though was I heated up the screwdriver then pressed that into the screw rather than heating up and melting the screw itself. Thanks for the idea.

[@hogmouthfishingcharters4546]

Just did that to my 88 mercury 70 horse came out with ease you're the man!!!!!!!!!!!!!! I heated up the screwdriver red hot and then just pushed it through.

oopcdayc your welcome

[@motomizfit2892]

I’ve been stressing about this but hopefully I can get it now using the flat head. Thanks even tho it’s been 4 years later lol

[@stevensavage6120]

Thanks for video! Was thinkin that might work. & it does.

[@markspears1167]

Thank you so much for the video!! I had to do this to my Classic 50 and it worked so easily!!!

[@colsonwamsley9452]

Yessir this is exactly the video I needed

[@kevinbrown1688]

You are, I mean, WE are not alone... :-)

Man o man I gotta try this thanks

[@nhjonesy]

Good tip, man thanks. Saw something similar on a forum that suggested heating a wide flat blade screw driver and pressing it into the bolt. Why on earth use nylon? Everywhere I read people are having issues with these things. I broke 1/2 the head off mine, but was still able to get the motor up because a welded plug blew out on top of the main cylinder (so all the pressure was gone anyway). I still needed to be able to work the nylon bolt in and out to bleed the unit after getting the blown plug fixed. I drilled a hole in the center of the nylon bolt and drove a 1" #8 phillips screw into it to provide some stability to the remaining part of the head so I could grab onto it with a pair of vice grips. I had to do this and bleed the unit in my bench vice. Yes, I could have waited for the new $40 replacement nylon bolt to arrive next week but my boat's been down for almost 3 weeks and I really wanted to use it this weekend!

[@chrisinkansas1362]

they use nylon so they bust off easy and then they can charge you 40$ to replace it! those things should never be so tight that you can't get it out with a screwdriver but anyway we all have to learn some how lol.

[@jackiechan3599]

Thanks just happened today. Fixed it and we're out of the lake now

[@MarkHolzhauer_Holzy]

Nice tech tip....Thanks! BTW, when my 86 150 Merc wouldn't go up I unscrewed the relief valve and lifted it manually.....not sure if your broken nylon head is for the relief, but mine isn't nylon and is on the opposite side. Nice Post!

[@fishingislife24]

Mark Holzhauer yeah it's the release valve

[@tommyt234hauser4]

Thanks I broke mine and will try your trick thanks 👍

[@nalvarez3505]

Thanks for shere this tips, I have question: do you know the part number to rebuild the trim and tilt for this motor I have same motor but I can't find specific one for it

[@fishingislife24]

Noe Alvarez Most of times the motor doesn’t go bad... it just needs brushes replaced that ride against the armature. Your local marina would have them

[@joshuarobinson2698]

I have a 1990 135HP Black Max as well. I'm going through trying to get a replacement right now also. I talked to my Marine repair guy. He helped me track down some part #s for this. I have to replace mine too. The OEM part# is 826729A10 - be prepared to shell out 1200 - 1400 bucks for this one. Its the motor and pump assembly - probably not needed, but Mercury wont sell them separate. The Sierra - replacement motor only is 18-6273-1 $662.52 I found a knockoff from DB Electrical for $141.08 part# 10815P Good luck!

noce clean boat

[@swifthoffman712]

So I have a 1977 Johnson 85 HP and I just bought this boat well the the motor would go down but wouldn't go back up so I put hydraulic fluid in bled the line and it was working great it was going up and down just fine then all the sudden when I went to press the button for to go up or down it would just click and kept clicking so I assumed it was solenoid well I replace the solenoid it stop clicking it wasn't doing nothing then all of a sudden it went down but it would not go back up and it made a weird humming noise coming from the trim area I am guessing and now it doesn't do anything doesn't go up doesn't go down doesnt click or any noises.. nothing do u have an idea what it could be ?

[@fishingislife24]

Swift Hoffman could be your brushes that ride on the armature. You'll have to take trim motor off to access these

[@zekeslaying7764]

any luck on the fix having the same problem

[@tombrooks2015]

Or just heat the screwdriver head and push it into the srew/bolt

[@fishingislife24]

Tim Brooks yeah works the same

[@motomizfit2892]

Well it didn’t work for me, all it did was strip out some plastic and now there isn’t enough left to get out 😑 anyone have another possible way to get it out

[@peterstrouss2002]

Me too. What did you end up doing?

[@peterstrouss2002]

I'm running out of ideas and don't know how else to get this nylon bolt out

[@motomizfit2892]

@@peterstrouss2002 I took a torch to it and melted it all out then clean all the plastic out with a pick and put a new nylon bolt in it. It was a pain and time consuming. I probably spent at least 3 hours on it

[@peterstrouss2002]

I'll give that a try. I haven't liked any other options that anyone had suggested, so I'll try this! Thank you

[@motomizfit2892]

@@peterstrouss2002 and I wouldn’t recommend it it lol after I did it my tilt never stayed up on its own I had to keep hitting the tilt up button to keep it up. I’m sure I ruined some seals or something
