How To Add Or Refill Your Trim And Tilt Fluid On An Outboard.




What do you think about this video?

jon beeler: I figured if anyone could answer this it might be you. Anyway,the T&T unit on my 50hp OMC sometimes gets stuck in the up position. You can still hear the units motor run seemingly normally. However,sometimes,when it sounds like it is going down,it simply isn't. Could this be low or watery fluid? Perhaps something worse???

Jim Mitchell: Great job!! I am a River guide on the Smith River in Northern Calif for salmon and steelhead check out some of my vids

therealpoorboy: Mercury is top 3 in the nation. mercury is the offical engine. nice video, #mercury 250 proxp skeeter zx210 

mathew Kane: I have no idea why people would buy a mercury

Stuart Scolnik: thank you. very hard to find this information. very helpful.

Carry Smith: question 4 u buddy,,i have a 1997 mariner 90hp 2stroke motor, would u say a propeller thats 13,25x19 will work well for my motor?..thank you

Generic User: Thanks for taking the time to make this video. I'm curious about CHANGING the fluid too. Do you know of a DIY how-to video for that? Either way, thanks!

ReelTeaseFishing: if it goes up but very slow or rough it may be because of the oil. drain the oil and refill using the method above. Too little oil and it wont be able to lift the engine properly. (which sounds like your problem)

ReelTeaseFishing: I'm not 100% sure, but I do believe they are pretty much the same. They work pretty much the same way. The screws might be located in a different spot though.

Jay Zundel: I have a 2003 Hydroswift and the trim wont go down. It makes a click noise when you push on the trim but nothing besides that. Any suggestions on what it might be?

MrQuack811: Okay, i have a 2003 mercury 175 optimax. i tried to completly change all the fluid by taking the plug out at the bottom of the trim. now that ive refilled it i cannot get the air out. everytime i lower it without the cap...i lose a crap load of fluid out the hole, then it makes a god awful noises going back up.(because it lost a ton of fluid) can you help???

Bruce Ginkel: Worked for me thanks. Used an Allen wrench though. Not a flathead. Cheers!

Twobuns Fischer: Yes Great video an how to add tilt an trim oil, I"ll be going to do my Evinrude 200hp. Thanks.

Steven Williams: I had to change the pump motor, now the piston stays in one position. Do you have to prime the pump a certain way? there's another screw on pump side

Jesse Staerkel: Nice! I got a johnson that goes down fine, but comes up very slow. Last night it didn't want to come up at all. Does that sound like low fluid or a bad relay? where are the relays?

ReelTeaseFishing: Every time you lower the engine, you will lose oil. make sure that if the boat is on a trailer, the trailer jack is set to the lowest possible or that the trim and tilt is sitting even. You don't want the boat sitting to high in the front, thus it will never allow you to fully fill your trim and tilt. Also if you cant get all the air out let it sit in the upward position with the screw cap off for about 30 min. then fill her up. cap it. lower it and allow it to stand another 30min.

ReelTeaseFishing: Glad it helped :)

CharlotteBaseball25: Thanks! This helped a lot!

ReelTeaseFishing: To jump on my comment section and tell everyone that my method is wrong, is very naive of yourself Mr. TXMAN. There isn't only one way to do everything. you will be surprised at how much you can learn by listening and observing. Have a great day.

Drummer Dave: So I have an Ocean Pro 150 Evinrude/Johnson 1993 My trim motor went out on me and I had to use the manual release to raise the motor by hand so i could get home. I replaced the motor and now I can get the motor to lower but it will not raise up. How do I purge the air and fill the fluid once I get to this stage?

MrTechReviewDude: Is there any reason to pay extra for the manufacturers brand fluid such as Yamaha or Johnson compared to something like Pennzoil.

George Zaleuke: Great video buddy. Would the Mercury T&T be about the same thing?

Jesse Staerkel: when I try to move it up, the hydraulic motor is can be heard running, it just doesn't move the motor, or it does so very slowly...

Steve Odem: i have 2002 yamaha outboard 90 hp. when im driving the boat and trim down as i come to a stop it makes popping noise, it only does it when in the water. if its on the trailer it doesnt make this noise, any suggestions as to what it might be ok that i can do? thanks!

Garland Endicott: my switch will not raise or lower tilt or trim r they any way to raise up a 50 hp mercury lower unit

txman201: If you fill it with the motor all the way up, any overfill will run back out if you give it a minute before you put the plug back in. DO NOT trim down without the plug installed. This guy is wrong, per OMC shop manual.

ReelTeaseFishing: Thank you :)

txman201: I don't know where this dude got his "how to" credentials, but when I look at the OMC shop manual it says the following: "The oil level rises as the motor is trimmed down." One or more of you confirmed this by discovering that fluid gushes out after you fill to the hole while the trim is up. OMC says "PUT THE PLUG IN, THEN CYCLE UP & DOWN, RECHECK.". Not everything you see on Youtube is correct or accurate, unfortunately.

ReelTeaseFishing: If this is the case because you powerload your boat onto your trailer, this is normal. The trim and tilt is two systems. the first is the trim, it has two pistons that raise your engine only slightly, then the tilt which is made to raise it completely for transport. the engine when under a load will not stay in the tilt position, it will lower to the trim where it should stay unless you trim it any lower. read comment above as it might help you as well. but seems like its normal.

ReelTeaseFishing: Mr. TXMAN, although you may be following the manual. That does not mean it is the ONLY way. In fact, the method that I am describing is actually a more time efficient way to fill your trim tilt. By not putting back the fill screw you will allow any trapped air to immediately escape. Thus if you put the fill screw back on, the air will get trapped and mix into the oil, then you will have to wait for the air to separate and escape taking a few hours. Although my method is messy, it works better.

ReelTeaseFishing: seems like their is air in the system. lower it using the manual release screw on the bottom side of the T&T

Paul Knittle: It could be that you need a rebuild. Water probably got into the electrical area and did some damage to the brushes. Try checking the oil to make sure it is not white and try tapping the motor to see if it will work.

ReelTeaseFishing: any power trim and tilt oil will work. You can find it at any of the local bait and tackles or big chain stores such as west marine, bass pro, walmart etc.

Tracy Marino: Great video, is there any other maintenance that is done to the tilt and trim system? Thank you.

ReelTeaseFishing: The trim and tilt is two systems. the first is the trim, it has two pistons that raise your engine only slightly, then the tilt which is made to raise it completely for transport. the engine when under a load will not stay in the tilt position, it will lower to the trim where it should stay unless you trim it any lower. the engine after a certain RPM will usually not allow you to raise it. basically your engine will/should not run on the tilt shaft only as it cannot hold the load.

ReelTeaseFishing: after that, uncap it and allow it to stand about 15 more minutes to allow any air or air bubbles in the oil to escape. fill to top and screw back on.

probowhunter1: can I overfill the unit by putting in to much oil

Roland Pope: I can only trim up and down while stopped, then when I do trim up as soon as I take off the water force pushes it back down! Is this fluid level?

moss midlands: hi I have the same problem as the one below trims up and down fine but when I take off the engine slides down and I cant trim up.but when I stop it trims up fine.is it maybe low on oil?

ReelTeaseFishing: You wont be able to fill it up if its in the down position because you wont be able to reach the fill screw. Your problem may not be fluid though since usually you will see the problem when the engine does not come down, or it falls slowly. If its stuck and wont go up, I'd say check the relays. there are two relays. One for up and one for down. Also do your hear any noise from the trim and tilt? Maybe low on battery? lastly I'd remove the pin connecting the engine to the main shaft and lift it.

txman201: OMC Power Tilt/Trim & Power Steering Fluid, or Dexron II automatic transmission fluid.

zeauz: nice skeg :D

Henry Brenlla: Any way to fill the unit once its stuck on the down position??

ReelTeaseFishing: you might be low on oil, when the system is low on oil it tends to shudder, shake and make all kinds of weird noises. its usually more of a problem trimming up then down. Check your oil level in the trim and tilt. and check the O-ring on the fill screw.

jay vill: ii got a johnson motor wath type of fluid do i put & its a 110 2stroke motor

shark pit: hi i filled with trim oil and got stuck on up position any idea?

ReelTeaseFishing: yearly checks on the oil and to check for water in the oil ( milky colored oil) and when not used or stored running the trim up and down a few times maybe 1 or twice a month to keep it from freezing up. other than that rinse with fresh water after every outing. you can always coat the trim and tilt (Metal housing) with some type of spray on grease or silicone to protect it from rust every so often.

ReelTeaseFishing: @zeauz Florida bay & especially Flamingo will do that to ya. :D

Kito: YO BRO great gd video. what fluid must i use. powersteering fluid? can i use amsoil power steering fluid i heard it's vry good.

Georooney: My Merc 90 HP outboard trims up and down sitting still, but will only trim up at planing speed. When I try to trim down, the OB makes a shuddering sound, like it's trying to trim but can't. What's going on?
