PART 2 MERCURY OUTBOARD POOR IDLE FIXED

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 been researching for awhile
... I'm 90% sure this is it! Thank you

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!

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!

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

[deanmartin]

What brand reeds did you buy? Did you have to rejet the carburetors after the change?

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.

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.

[ryanjames]

Great video, Reeds and Reed Valves are another item that needs to be checked.

[livindahdream]

I have a 1989 200hp Mercury and some of the issues you are mentioning has helped me on my issues so appreciate the video.

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

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.

[griffind]

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

[larrykaminski]

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.

[whattheflock]

Sounds like exactly the same issue as my 1985 merc 150 black max. Thanks for the walk through!

[jeffp]

Was the compression ok when the reeds were bad?

[mikemelton]

Do you have a video actually showing start to finish changing the reed assembly?

[garyallain]

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

[franciscallahan]

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!
