Not sure that I approve. This engine called for a thorough valve job at minimum. A wet/dry compression test would have revealed the condition of the piston rings. If all yo7 want to do is “get the motor running” as Steppinwolf said, then ok, but taking the head off is more than halfway to a valve job/piston ring overhaul.
@Born Again Boating what are symptoms of blown head gasket on a 2 stroke. And can it be possible to have fantastic compression but a failed leakdown test.
I reconstructed half of the thermostat housing on a Yamaha 9.9 "Kicker""Trolling" motor with J.B.weld and sold the boat 2 years later.I told the new owner about the repair and as far as I know it still works.CHEERS from Here!
I love this guy. He's sharing his knowledge and expertise with us. Stuff that takes years of experience to learn or expensive training. I learn so frigging much from everyone of his videos. He teaches in a complete and thorough way and keeps it all visual and in layman's terms. Bro I can't thank you enough. No local mechanic I know would take the time to show me how to do his job😂. I live in Florida near Daytona beach. Id love to meet you someday and shake your hand and thank you personally. Thank you again for being such a good guy.
hes right about j b weld it works i have used it several times my son had freon leak on his ford i fixed with j b weld i used it on an out board motor highly recomend j b weld
WE have used Yamaha Ring Free for decades and it really keeps carbon at bay. On the old two strokes and now on four strokes . It really works. Heavy in fuel before an oil change then dump the dirty oil.
Great channel! I mix my jb weld on a metal plate and heated, until it got liquid some what. Then applied it. Worked well had no issues. Good luck, boys!!
Oh no... We must take this boat out to test it in gorgeous weather! Great channel and you inspire me to take better care of my boat although its a fresh water boat so I think I have it easy! :D
Interesting fix for the Merc.....Had a simple fix for my Proline fuel system the other day and you folks had the part to get my vacation off to a great start with a 25 lb. Wahoo.....Sea Ya!!
Assemble the motor and run a few quarts of seafoam & good non ethanol fuel.. should help some of the build up. My Merc 25 had that same build up of carbon and after running seafoam through it , seemed to do the trick
Great episode! I had an old Evinrude 25 from the 80's. Excepte crept for the valves, I think I made all of those qwick repairs over the years. She eventually developed a pretty nasty knock. I felt like I got all of the life I possibly could from that motor. Nice watching you guys work. ✌🏼
It is amazing what you can do with in weld. I have repaired jet ski carb throttle shaft bushing surfaces,the actual carb casting, with in weld. I never thought it would hold but it did. Saved from buying a $900 set of carbs with $10 of in weld.
What was the repair cost? Great job. You guys always hit the mark. My lower oil seal under the power head is leaking slightly. Wondering what I might be in for to remove powerhead and replace it.
Replacing that gasket is pretty easy. Disconnect everything that attaches the power head to the bottom housing. Remove the bolts/nuts (depending on motor) and lift up. Remove and replace the gasket and reassemble.
These outboards can be worth more than the boat. The game is more technical than ever and the investment for multiples can be enormous. My outboard guy was old school and always pulled the heads before pronouncing on a motor. He never steered me or anybody else wrong.
Kid with man bun dude u need to pay attention to every thing this young awesome young man is doing because it's not in no book and there old 40~50 yr men don't know what this outboard master is teaching So Pay Attention it's worth it's weight in gold awsome job young man !
Nice fix. I love your videos. What caused that cooling fitting to fail below the powerhead in your opinion? Do you ever de-scale outboards? Thanks for another informative video!
I think saying how old the engine is and how many hours it has would add to the video content. Great job! Are there any additives / products that cut down on the carbon buildup?
I think he used that same motor in a "Flushing Info" video and said the Impeller had about 200 hours on it, but didn't say if it was the original impeller. So apparently the motor has at least 200 hours on it.
Hello sir really nice video you guys did on the one motor thumbs up I was wandering I have a two stroke Johnson 115 seahorse the year is a 90 that I really love I was told that the bearing are going bad I really would like to rebuild it myself but don't know we're to start would it be worth having it done verses buying a new motor that now says only the boat dealers can only work on I would really like to hear back from you thank you
That's a tough one lol really depends on the budget, and then also depends on where you are and what's available. Depending on who is the one that is going to rebuild it, are the parts available to rebuild it, how long will it take to rebuild it, what's the components on the engine look like, are they looking in good condition or are they in rough shape and potentially need to be changed? Lots of variables there my friend :/
I am following you for some time and really apreciate help from your videos. I have 2015 Verado 225 with 1000 hours, bought it with 200 hours. In few past days I felt that on idle motor shakes a bit, rpm is good, stays calm. In gear shakes a little untill gets more throttle and then normal up to 5500 rpm. When I changed spark plugs motor was in water, so when I took out 3rd plug I could hear air draught through chylinder while sea was going up and down through the leg and exhaust. Is this normal because exhaust valve is open in that moment or there should not be air through cylinder when plug is out? I felt this only on 3rd cylinder. Should I do compression or leak test? I cleaned injectors, changed plugs, all fuel filters... thanks for advices
If you have an angle torque of 270 degrees, does that mean theses head bolts stretch and are one-time use? Won't refusing them allow them to break or loosen?
The cam gear bolts are reverse thread? I guess im definitely getting a suzuki. No reason why any motor should be prone to jumping timing if made within the past 15 to 20 years.
Hey bud, I’ve got a 200hp Verado 2006 and I’ve been having problems with it starting, sometimes it starts but only when it’s cold, never starts when it’s warm just cranks, I’ve been trying to fix this issue for the past year but no luck as there’s not many of these engines hear in Aus, the motor is in really good condition, I’m guessing it’s something electrical but no luck finding it.
Very interesting. Would consistently adding a decarbonizing agent to the fuel have prevented or minimized the carbon buildup on the valves and pistons?
? I have a 2004 250 salt water series can’t get rpm over 4400 New prop temp fine plugs good runs smooth as silk only thing haven’t trim is making a noise when I try to put engine down under load rpm with no load runs up to limit help please Love your channel wish had some good mechanics up north like u they just like to replace everything till they do or don’t find problem at your expense lol
Was it impossible to tig weld it on the spot and after that just secure it with that epoxy glue?Do you have options for some specialized machine shop to fix that head?valve seats,valve seals,grinding...i think what you did is just cosmtic.I love your chanel ,no hard feelings .And why saving someone who spend amount of fuell that cost for one weekend as someone's week sallary?Sorry for bad english.
I have hard of doing it cheap.... but what kind of customer is going to be okay with the fix being JB weld? Usually I see very professional fixes from this channel but not today.
As a former aircraft mechanic, but in my defense, I worked on turbines, I can't figure out how the leak down differs from a compression test. Obviously not the test, but what would a compression test tell us about a leaking head? Or.. would it not locate it accurately??
It doesn't work the same because there is a check valve in the compression tester hose that allows the pressure to build in the gauge with every stroke. Then holds it there to get the compression reading. The leak down doesn't have a valve and puts pressure in the cylinder
Momentary vs continuous. You need a constant flow(leak down) of air to pinpoint a leak. Also all valves need to be in closed position. If you hear/see air leaking through: 1. Exhaust = exhaust valve issue 2. Intake/throttle body = intake valve issue 3. Cooling/coolant = head gasket 4. Crankcase/dipstick = piston rings.
From the 100' view they can both diagnose a low compression problem, but the leakdown tester provides a steady stream of air that can help you more easily diagnose exactly where the air is leaking. Also a compression test result can vary by the cranking speed, throttle position, etc.. and the leakdown result will be more consistent because the stream of air is regulated and always the same.
Am getting into boating just retired 😂, what made the excessive carbon buildup, could something as simple as wrong fuel caused it? I worked a lot with supercharged engines as a hobby on cars, could fuel additives help, running lean on car engine supercharged is begging for trouble, I enjoy your videos thanks
You should disassemble the whole damn thing to make your work more efficient. Clean up and repair damaged items piece by piece and assemble them back nicely.
Thanks for the video. Gives me a possible idea of what’s going on with my ‘16 350 Verado with @120 hrs. Around 4k rpm it starts jumping rpm. Also my father who grew up wrenching in his father’s service station says he hears a misfire. You have any ideas? Marina tech said they had to replace a resistor. But it’s still doing it and confirmed it with going out with one of their Captains. He heard it as well, yet the techs can’t seem to figure it out.
@@KillinTimeHuntingFishing thanks for the input. I’ll check it, but I don’t think it’s the case because when trimmed all the way down and even when Captain Kevin took it out and gradually sped it up to plane, once the rpm’s get to @4k it starts jumping around looking for a place to settle in. If that makes sense. Driving me nuts bc I’m not sure if it’s killing my fuel consumption, or doing other damage. Plus it’s a new boat for me. It’s flawless except for this issue.
On older bolts, I always used to soak them first, in my 41 years of working on engines, you're bound to break a few. Just make sure you have a Tap and Die kit laying around.

thanks :)
Hey how many hours are on those engines ? Just interested to know
@@crustymac1326With a cylinder down that baby's gotta have more than 700hrs, at least or abused.

If all yo7 want to do is “get the motor running” as Steppinwolf said, then ok, but taking the head off is more than halfway to a valve job/piston ring overhaul.
You should never clean the cylinder head and engine block deck with a scotch bright pad it creates low spot inperfections.
Man I love this channel, you can't get anything more real than this, good job guys!
thanks so much!

Great job with the fix and ultimately saving the customer big dollars!
I really enjoyed this longer video. You gave that engine a second life!

Definitely a $3000 repair , even with JB Weld . Nicely done in a day, unreal , what dedication.

good part about you can sand it if needed in an hour in summer time i dont use below 65 deg.
You guys are very talented mechanics!!!!
That was a great trick with the die grinder and abrasive pad!

Extremely satisfying to see you bring this one back to life!💯 👍
Man bro it’s crazy that you know so much about this trade keep up the videos and knowledge
Nice fix. I love your videos. What caused that cooling fitting to fail below the powerhead in your opinion? Do you ever de-scale outboards? Thanks for another informative video!
Great video. What was the decarbonizer product you used?
There’s another video for your library, good job.
Outboards are CRAZY expensive for what they are. For $20K you could buy the Highest end racing engine for a car. Not just a old 250hp Verado.
Good vid man, listening to it while getting out fuel with water in it out of a boat lol fun job
G,day from Sydney Australia. Can you seat the cylinder valves? Use valve lap paste and connection of a drill to each valve stem?
💫🇦🇺
That was the best explanation of getting to TDC that I’ve ever heard!
I think saying how old the engine is and how many hours it has would add to the video content. Great job! Are there any additives / products that cut down on the carbon buildup?
Seafoam

Yeah definitely that motor has more than 200hrs on it.
Power tune in the throats
Great video. What did you use to clean the surface of the block?
You know your stuff young fella 👍

Impressive gentleman I enjoyed watching that.
I enjoyed the video. I loved the troubleshooting parts. As a shade tree mechanic, this is a project I would definitely do. JB weld, bring it!
We just pulled a couple power heads on mercury twin 300s. Let me tell you what, that was a process getting them both broke loose

What about regular valve and seat lapping?
I put jb weld on my sons truck on the water thermostat housing going into the block. It has held couple years now no problem that perfect for jb weld
Wish you were located in the tampa Bay Area 👍. This guy knows what he’s doing
Great video!!!
If you have an angle torque of 270 degrees, does that mean theses head bolts stretch and are one-time use? Won't refusing them allow them to break or loosen?
Great work. How many HRS are on the motor, sry if it you said it. A little freshwater wouldn't hurt. Wow, rinse.
Sir, 1,822 Hours.
Damn strong hands..
Awesome vlog.
The cam gear bolts are reverse thread? I guess im definitely getting a suzuki. No reason why any motor should be prone to jumping timing if made within the past 15 to 20 years.

Great job!!! How many hours did that engine had on it?
What was the cause of the carbon build up ? Any ideals ?
Very clear and concise, thank you
Have you had any trouble with head gaskets sealing after using small rotary tools on the block and head to remove the old gasket material?
Very interesting. Would consistently adding a decarbonizing agent to the fuel have prevented or minimized the carbon buildup on the valves and pistons?
JB Weld and send it!! How long do yu think that will last before a re-power?
Owner will likely sell it like this and not disclose the information to the new owner.
Great video !!! How many hrs on those units and what caused the carbon build up ? Dirty fuel or too much idle time and heat ?
Toward the end of the video you can see 1822 hours on the gauge, I was wondering the same thing.
I wish you guys were in Crystal River
Jb weld should be sponsoring the channel with good review like that
Another save from the scrap pile
? I have a 2004 250 salt water series can’t get rpm over 4400
New prop temp fine plugs good runs smooth as silk only thing haven’t trim is making a noise when I try to put engine down under load rpm with no load runs up to limit help please
Love your channel wish had some good mechanics up north like u they just like to replace everything till they do or don’t find problem at your expense lol
Increible,👏👏👏 fantastico video💪
when the head gasket blows, does it typically happen between the 4 and 5 cylinders? great video!
How many hours on that motor ? Did they periodically use any fuel treatment?
11822 hrs. ......Doesn't look like any treatment was done beforehand.
Now I know why that brand new 1993 200 merc I bought head gaskets always leaked. It was that special mercury torquing technique. 😂
Whats the engine temp at 5k plus???
So Merc also has a cam chain now!
I thought that the Suzy's was the only brand that had those.
Was it impossible to tig weld it on the spot and after that just secure it with that epoxy glue?Do you have options for some specialized machine shop to fix that head?valve seats,valve seals,grinding...i think what you did is just cosmtic.I love your chanel ,no hard feelings .And why saving someone who spend amount of fuell that cost for one weekend as someone's week sallary?Sorry for bad english.
I have hard of doing it cheap.... but what kind of customer is going to be okay with the fix being JB weld? Usually I see very professional fixes from this channel but not today.
There is no proper fix other than throwing it out and buying a new one. JB Weld bought the customer some time that's all.
I like the work bro 🛠️
What yr engine and hours????
Do you have a video on how to remove seized screws on a fuel tank sending unit plastic tank how to remove them
I love this daily boating content. Wven tho the season might be over soon, you always gotta keep up the passion!!
AWESOME JOB GUYS I JUST SUBSCIBED TO THE CHANNEL!

I agree, he should of stripped it down to the bare block. He may have warped heads on a engine that old. It had 1,822 hours !
For rust muriatic acid aka pool acid works wonders
Great video - how many hours on those motor's?
It shown 1822 hours.
How does the 34 venture run with the 300 verados? What is you top speed and cruise?
should done complete engine rebuild...
I think the $300 must have been for the JB Weld fix alone.
Thanks for the video. Gives me a possible idea of what’s going on with my ‘16 350 Verado with @120 hrs. Around 4k rpm it starts jumping rpm. Also my father who grew up wrenching in his father’s service station says he hears a misfire. You have any ideas?

Check out the Trim sensor, if it’s reading is incorrect it may believe your engine is not in the water or too high to run.
@@KillinTimeHuntingFishing thanks for the input. I’ll check it, but I don’t think it’s the case because when trimmed all the way down and even when Captain Kevin took it out and gradually sped it up to plane, once the rpm’s get to @4k it starts jumping around looking for a place to settle in.

Seafoam or marvel mystery oil engine carbon cleaner: $8.00. Just put it in the oil and fuel.
so jb weld is how we fix them , give me an old 2 stroke
Would love to track how long that JB Weld lasts
Great video as usual, what caused all of the carbon build up and what do you recommend to prevent it?
Using only ethanol free gas
Engine was run too many times under light loads. In my opinion.
How many hours is on that motor that lead up to this? Or was it just lack of proper care?
Is it safe to run Verado on the flushing attachment ?
Just saw your new video uploaded today about this, great timing lol. Thank you!
Hours or lack of maintenance or just Mercury?
WHAT DO YOU THINK CAUSED THE HEAD GASKET TO BLOW?
How much this job cost this day’s?
How many hrs on that motor
I dont remember exactly, at that time I think there was like 1500 amd then we put another 800 on it and then repowered, engines still running today :)
How did you get those head bolts out! I always break at least one.🤣
On older bolts, I always used to soak them first, in my 41 years of working on engines, you're bound to break a few. Just make sure you have a Tap and Die kit laying around.
How many hours did this engine have?
