PART 2 MERCURY OUTBOARD POOR IDLE FIXED
Вставка
- Опубліковано 19 кві 2019
- I completed the repair on my mercury and it was exactly as expected. The repair is very simple if you have a few hours to commit to the job. The only tools needed for this were a 3/16 allen wrench, a 7/16 socket and crescent wrench, and a phillips head driver. The reeds I used were made by CCM and are quality fiberglass parts. Apparently the OEM stainless reeds are known for shattering and destroying outboards. If your motor is tough to start and idles poorly but runs good at WOT, check your reeds. Id like to thank C&O Marine for coming through in a clutch and Chris Carson Marine for the amazing products. Thanks for watching!

I've come across many a broken reed petal, and each time the engine just sucked it in and spit it back out through the exhaust. never been able to find the pieces. HOWEVER it's also possible the piece of reed is stuck somewhere in the crank case, waiting to get dislodged. That's why i change many a customer motor to fiber reeds. just like you demonstrated, they start 3x better and have more power. best investment. ever!
After spending the better part of a couple of days looking for that random little piece of broken reed and assuming it went out an exhaust port in tiny chunks and assembling the engine and putting it in the tank to run it to check out everything and adjust carbs etc. After about ten minutes of run time started hearing that dreaded rattle and pulling the engine out of the tank and pulling plugs to see if there was any serious problems found a few little pieces of the offending reed sticking in the top of a piston so down it came again and to see if it was going to need a new piston or what pulled the covers for the exhaust ports (it was a vertical inline six cylinder) and wouldn't you know it, there inside the exhaust port covers was the rest of the offending reed valve petal. Learned a really important thing, that it isn't good enough to just shine a flashlight in the cylinder and blowing it out with a air hose and cleaning solvent spray. Them little things are like beach sand, they can and will get into the tiniest of places.
@@horsepower711 yes. sorry that happened, but i wouldve taken it to a machine shop that does 2 strokes and bored it then had them clean it in a hot tank to get rid of every last particle.
I was taught that the easiest and fastest way to check for a damaged reed assembly was to simply slide a business card in front of the carbs one at a time and if it flutters or has any kind of kick out away from the carb you have a broken reed or damaged reed block. On the older four cylinder inlines you would sometimes run across the symptoms but not find a damaged reed on any of the blocks, but don't quit yet because when you pull the reeds off you're going to find a little crescent shaped nick in the aluminum reed block where for some reason the reeds would contact with the tip first instead of hitting flat and would cause the little nick that would make the engine idle bad but until the reed would eventually break it would seal good at higher rpm. But we used a flat piece of 3/4" glass and 400 grit wet or dry sandpaper and cleaning solvent with a little oil and work the reed block in a figure eight pattern checking often until the blocks were smooth with no sign of the nicks left. Then reassemble everything and it would be as good (if not better than new
I have a 1998 Mercury 250 EFI 2-Stroke. All these broken reed valve videos were freaking me out because I fish very far offshore. I ordered some carbon fiber reed valves. But when I removed my old ones, the previous owner had already changed them! They were carbon fiber and looked brand new! I’ve owned the boat for 4 years. They looked so good that I could have boxed them up and sold them as new to somebody.
hello, I have a Mercury 15 hp and I'm going crazy for the same problem, giving gas it goes and it goes well then it turns off. I cleaned the carburettor and replaced the fuel pipe, today I will also disassemble the valves. thank you very much for sharing your work, I will update you! Greetings from Italy.
I replaced all my spark plugs today. Three were loose and all of them were fouled. Solved all the symptoms and problems as discussed in this video.
Always start with the most simple solutions first.
Thanks for the video!
Just got through watching your videos about the reed repair on your mercury outboard. I saw how excited you were after starting it up after doing the repair yourself. I try to do a lot of repairs myself, and I get the same feeling when I accomplish doing something like that. Great job, and great videos.
Thanks John!
I have a 1989 200hp Mercury and some of the issues you are mentioning has helped me on my issues so appreciate the video.
Great video, Reeds and Reed Valves are another item that needs to be checked.
Great video. I have the same issue on my Merc 125 15 years old. Going to start with the carbs, never done, and if that doesnt work will do the reeds. Thanks
Informative and detailed. Not sure if any of this relates to a 115HP Merc made in 1989 but this will get me started. Thank you.
My reed valves came loose on one side of one block and cracked a reed apart. The screws could not come all the way out because it's so close on the inside of the intake. But damage was still done got into 2 rod bearings that broke apart and got inside the engine and took out 2 rods 2 pistons 1 crankshaft and 1 head, not a happy day for July 4th. 1994 Mercury 200hp 2 stroke now got everything rounded up, just need new reed valves and overhaul kit. Just what you want to do in August heat. I've watched several of your videos and decided to do it myself, like you said big weed eater motorcycle. Allen Shifflette
I just bought a 2004 Mercury 200 and I've had the same kind of issues. I burned up my starter yesterday at the boat ramp. Gonna check the reeds tomorrow. Thanks brother.
My reeds looked okay, I guess. None broken, but it looked like some of the ends weren't making a great seal against the housing. Could this have been the reason why my boat would randomly go dead at idle and take forever to start?
Yep
You helped me figure out my bad idle my number 4 cylinder sucking in half a reed glad I did it myself instead of taking it to a shop
Thanks 4 making this type of video. I'm having this same problem.👊🏿
Sounds like exactly the same issue as my 1985 merc 150 black max. Thanks for the walk through!
I have an 85 mercury black max 150hp as well. It has a hard idle and sometimes dies. Especially while idling in gear. Also takes forever to start sometimes. Did re working the reeds work for you? Or was it something more than that?
Thanks for the very detailed videos
Again, Thanks for sharing the knowledge! first time I ever saw a reed valve, that I know of.. lol
Excellent...think I found my issue...you the man!
What brand reeds did you buy? Did you have to rejet the carburetors after the change?
Yeah I wonder where the piece went
Appreciate the info brotherman!
I’m having my reeds replaced next week. It’s good insurance so a broken reed doesn’t damage a cylinder.
I had the same issue on my 99 xr6 150 poor idle, after much research carb rebuild first. same issue poor idle, so more research, thank goodness for parts books and internet, found two reeds with bad chips, broken, researched reeds, my dealer was too expensive and wanted to sell the complete reed block. found Chris Carson and he was great help. One thing he told me to do was to use 400 grit or better paper to lightly smooth out the blocks over glass with water. also putting the screws back in used small screw removal loctite. I'll ask now, how much was the stuffing box improvement to the engine. My reed replacement was 6 years ago and still work fine. but bought stuffing box and reeds too. thanks for the great video.
Awesome man! Glad I could help! The stuffers reduce the crankcase volume which will give slightly more torque on the low end but at an equal cost on top. I found that the 2.5L 150 didn't really need the torque boost due to the long tuner. They definitely have their place in the performance world but it depends on each individuals needs. I haven't tried them on a more open exhaust setup to see if the torque gain is worth the rpm loss up top yet but I imagine the benefit would be noticed. Especially on a heavier boat. Just my thoughts and experiences. You'll hear people with opinions on both sides.
Man that's awesome glad its fixed brother. I bet you will get a better top speed as well 😁
you dont need a new check valve in front of low pressure filter as the Y in the fuel line past that point is in fact a brass check valve from the automatic oil injection pump, when the motor isnt running the oil isnt being injected so there is NOT a dilution problem
I've just received CC,s reeds and stuffers and also head studs as I will be shaving the heads a bit and I don't want to break any bolts in the future. And maybe advancing the timing a degree or two because we have reasonably good 98 here in Australia.
I've been looking for a video on this for ages. Thanks.
It's a low hour 94 2.5L offshore.
Nice work!
If there's one thing that hit home it's when you said...."Now I won't be sitting at the ramp for 15 minutes trying to light it."
2003 Ranger VS175 Mercury 125 ELPTO
Sounds like I’m having same trouble, hope this works. I will let u know how things go
I'd love to know more about that inline fuel/water serperator. I've never seen that before. I have a 1992 Merc 150 Black Max that could certainly use that filter.
Hey man! You’re videos are a great help! I’m having a little trouble with my motor as well. Was thinking about getting the carbs cleaned and tuned but when I go to do that I will also check out the reeds thanks to you! I do have one question buddy. When you start your motor, how long does it take for your water pump to begin pushing the stream out the motor? Mine takes a decent little while and it scares me that it may overheat due to that.
At idle it usually takes a couple minutes for the thermostats to open. Its normal.
I appreciate your videos
Do you have a video actually showing start to finish changing the reed assembly?
Yes
Maybe it broke little pieces at a time getting progressively worse. Good video. I am having my own issues with an Evinrude etec I bought used. It was supposed to run but the guy who sold it to me was lying his tail off. My reeds were not broke but I think some carbon may have been keeping them from closing.
I hope you gave me the answer, I have an 18' Sea - Doo with a Mercury 250, same exact symptoms. I only had it out 2 days and wont run.
Great video! One suggestion. Can you stop the music after the intro.
Nice fix I hope I find mine
I hope its just my reed valves also.
I rebuilt my carbs. New fuel lines zip tied all my vacuum hoses and fuel lines. It started up 5 times in a row. Once I dropped it on the water. Zero start. Frustrate the crap out of me.
Nice repair!
Was the compression ok when the reeds were bad?
Finally a fix it vid
Great vid
Thanks!
Really enjoyed your reed installation and stuffer videos. Are there any torque specs to deal with? I do not possess a torque wrench. p.s. I have the exact same xr6 with the exception mine is a 2002,
I have a 2005 Mercury 50hp outboard that does the exact same thing. It runs great on open water, but idling at the dock or taking it on and off the trailer is almost impossible. Does a 50hp have the same reed type setup as your 150? If so, let me know when you're gonna be in florida and you can show me how to fix it lol!!! Awesome videos....thank you, and keep up the good work.
I would suggest you either get a manual for that motor or open it up to take a look. But to answer your question, yes, it has reed valves.
@@SmalltownBassin Thanks 👍
@@db9230 I got the same motor but 2007. I do have the service manual for it if you need it. my acting the same way. On my it was a fiber reed valve. but found out it was carburetor flooded. rebuild carb and now all good. that was a simple and easy carb to work on. email me tonyvu16719@yahoo.com. I can direct to the service manual link.
I want to replace the reeds on my 200 Optimax 3.0L. Is it difficult to remove the intake? And put everything back together? Any tips? Also do you have to re prime the oil pump after or any special recommendations? Appreciate your input!
It's very similar to the 2.5L. Yes, you will want to prime both fuel and oil on yours when you're done with the reeds.
Hey i have the same issue on a 100 Mercury..fuel coming out of the carbuerator and hard to start
my did the same thing. end up to be the carburetor float seat needle. I rebuild carb and it running good now. If you want to know if it a carburetor problem or reed valve. Get a piece of duck tape just about a size of carburetor intake. place it on top of of the carb opening. Make sure seat the tape secure to the carb body. crank engine a few time and watch the tape. If it try to suck in. Then it not your reed valve.
@@tonyvu167191 Hey thanks haven't really used the boat but i am going to try this.
You have the exact OB I have, but I am trying to confirm this. I just purchased it a few months back.
Can you check your OB right behind the throttle arm, toward the top, there should be the letters "CC" stamped where the two halves of the block come together.
Would be very much appreciated !!!
Its a 2004 xr6. Should be the same block on any 2.5 L from 2000-2008
Cc block is a 175
@@boatsandjeeps780
thank you... good to know
Can you show where reeds are
I got a 94 18 ft bowrider Sea Ray with a 135 Black Max Mercury two-stroke oil injected can I do the same thing to that engine
Yep!
Thank You for this vidio...😁
Wonder where the missing piece of valve went. All through the cylinder? Out the exhaust? 😅
That's exactly where it went. I was a lucky one. The reed pieces are so thin and small they were passed through without damage. Very lucky for sure. Had a piece made its way between a bearing or piston, things would've been different.
Do the late 90 early 2000 2+2 mercs have reed valves??
All of the two strokes do
Hey man before u fixed it did it run better trimmed up than level my boat is doing that
received my reeds and suffing parts Is there a special way to install the spacers, follow the gasket impression, ? sent email to CCmarine too. thanks for all your help.
Put the stuffers and reeds on the intake but dont tighten it all the way down yet. Put the intake assembly on the block and then slowly start tightening the reed cage allen bolts. Be careful! Dont want to crack a cage.
Do you have a link for the parts? Or a part number, for the gasket and valves?
Yes. Check out my most recent videos that include all of that information. Thanks for watching!
Ok ok keep fishin thanks
Omg wish I had seen this before just give a go ahead to replace mine $1000
James Cole 1000$ to replace ur reeds?????? Omfg wowwww lmao
what caused the reed valve to get that hot ?
Lean sneeze
I have a 2006 mercury 1.5 90hp
And it does the same but it shuts off .. no idea if this will help!
Every got yours fix? What were the problem
RuffRize Rise I believe the ecu got replaced and a coil along with the spark plugs.. I currently have misfires so I bought all new coils to match each other and I’ll change the spark plugs again. Boats sit for so long it’s always something.

Question? So do older outboard have reeds. My boat is a 93 Bumblebee original motor.
if you have a 2 stroke outboard then yes your motor will have reeds...
I have a question. After the reeds and stuffers did you have to make any carb adjustments
No. If you take it a step further and add intake spacers then you will need to jet up but just reeds and stuffers don't require any adjustments.
@@SmalltownBassin ok thanks well I did add a 200 bobs tuner.we are also jetting up to 175 jets. Thanks for your feedback
Did you do all the Reed valves?
Yes I did. I've uploaded another video that shows in detail how to install them. Please take a look at it if your interested. Chriscarsonmarine.com can supply you with anything you need to do this and I encourage you to give them a call. Dont forget to tell him who sent you!
Where you order the part? Couple of them broke, and I couldn't find any online.
Chris Carson marine. He will take good care of you.
I got a 50 hp mer...it is tuff to start but if I use my finger take off throttle cable I can get it. Help it is a 83
sound like flooded carburetor. Not enough air.
I have a the same exact motor except 2000 model. I have the hard start, rough idle but I also deal feeling of lower power in hole shot when livewell is full and my speed is down. Just curious how fast your boat runs pre change and now?
tuffdaddy1711 ur over proped
@@reddawng43x91 actually my prop is fine. Found out i had a bad spark plug. Changed all of them and now she runs great..
tuffdaddy1711 glad it worked out that simple
Where is the carb rebuild video?
Never did it. There are too many already.
Small town Bassin' I figured it out, thank you though.
Mine aren't broken but they have taken a set and no longer seal.
Mercury makes a cleaner that is used by spraying it into the carburetor(s) following the directions on the can. When I was still working (certified Mercruiser & Outboard mechanic) we had an elderly man bring his boat in that had an old Mark 35 Mercury outboard that wouldn't idle on all four cylinders and was hapard to start too. It failed my credit card test so I informed the gentleman and he said he couldn't afford the repair costs. I felt really bad for the guy since he was a local and I knew his past couple of years had been pretty hard on him so I told him to give me another day and I'd try a couple of Hail Mary's on it. I'd noticed that it smelled of old gas and there was oil coating everything so I was thinking maybe a reed block had something stuck to it that might have found its way into the crankcase from a carboned up exhaust and a can of the cleaner wouldn't hurt, and who knows, even a blind squirrel finds a nut occasionally. After putting a can through it and choking it out by flooding it with the cleaner I let it sit overnight and the next morning pulled the plugs out and spun it a few times and then throwing four old plugs from my toolbox in it and fired it up and ran it for about a half hour at different throttle settings both idle and full throttle it finally burned out all the cleaner and I shut it off and put his new sparkplugs back in and tried it again and after readjusting the carbs it was almost as good as new and would now idle and fire up with just a bump from the starter or before you could pull it p
Before it was hard starting and would only idle on two cylinders and at full p
well you found the reed was broken, and yes your right its a steel reed, then you got new reeds to fix it, then fitted them WRONG, you should of delved down into the guts of that motor to try and find the missing part of the reed before it destroys the motor. the worst thing you can find is a broken steel reed, it means you need a complete teardown to find the broken part or if it going anywhere near the piston and wall or the big ends or small ends you could have a completely destroyed motor. those broken metal parts dont just fall out the bottom, so if you cannot find them with the intake off then its a teardown....
What you're saying is 100% correct. In this particular instance though, the pieces were not in the crankcase or cylinder. Trust me, I looked. I've got too much invested into this just to blow the motor over a Reed. The only explanation can be that the piece was pushed out the carb instead of being sucked into the crankcase. Thanks for the comment though. Your input will help others with a similar issue.
But don't you wanna know why these reeds failed??
good job done on changing the reed valves,,,,, but,,,,,, were has the broken part of the reed valve gone?,,,, you never found it!,, so it has got to have gone inside the engine!,, its either stuck in the crankcase or its gone up into the cylinder and have been blown out the exhaust or it could still be stuck in the top of the piston, so just swopping out the broken reed valve and ""not finding the broken or missing part!"",, running this engine you are tempting providence,, this engine could still go with a bang on you and rip its self to bit's!,, never ever just change out a broken reed valve and then run the engine,, unless you find the broken part of the reed valve first!,, I hope you dont find out what your mistake was,,, the hard way!
Gubber
Too much talk. Frustrating
So glad did video and showed this! No scoical media but email is samheather4always@gmail.com
Thanks Sam!
Chat less get to the point? You could have done a compression test to determine if the reeds were bad.
Video could be a fraction of its length if this dude didn’t like to hear himself talk and tell stories in an exaggerated southern accent. Next…
