[@inthisdayage7617]

In conclusion after reading 75 replies: anyone who asks a question in here will 100% not get a reply so dont bother asking questions here. However you will get a thumbs up. Yay! 2nd it seems the jury is out on Sea Foam, the guys who use it either have mixed results or terrible results the guys who use it and say it's great are few. The replys I read against using sea foam seem much more valid with good explanations. Verdict is hung jury. My advice: just do regular maintenance, use proper fuel oil ratios 100% of time, dont use last years gasoline, store motor in building above freezing during winter, run all your fuel out of motor when in the water before trailering by disconnecting fuel supply line until engine dies, dont be afraid to use full throttle for more than 15 minutes during every outing, and let motor run for several minutes before taking off and lastly dont use premium octane in motors built for 87 and 89 octane. Avoid ethanol. And when rebuilding carb kit only use factory and never aftermarket plus never forget to change out the float when doing carb kit cleaning/ rebuild. Tip: put a marker board in your garage and log all your small combustible engine specs and always winterize your engines. I guarantee if you follow these basic guidelines you'll be able to run your same outboard until your grandson is ready for a timeless hand me down. As of right now the only thumbs up is my own. 🤣

[@PrestigeWorldwideFishing]

👍 similar to your body. Don’t ever eat fast food or anything in a box or bag, exercise, take vitamins, get 8 hours of sleep and you will live to see 100. Unfortunately, like our bodies people don’t take perfect care of their boats. This isn’t a miracle drug but does help depending on if there isn’t other underlying issues. Thanks for your comment and input. Good luck on the water

[@randymiller5008]

90 octane Ethanol Free Gasoline is the only fuel anyone should ever run in an outboard. Any other fuel shows just how big of an idiot you are... Period 🙄

[@selectweddingfilms_cny]

Why not just add it to a gallon of gas in your tank?

[@PrestigeWorldwideFishing]

You can, just might be hard to estimate how much gas is in your tank… at least it would be in my boat.

[@steadfastangler8706]

sea-Foam is great... actually works, I put it in ALL of my gas powered equipment and vehicles.

[@ripperace]

One thing “power tuning” (what this process is known as) does, especially on two strokes, is decarbons deposits between ring lands, and frees stuck piston rings. I’ve taken some customers two strokes that were known to be mixed rich, and had varying compression numbers between cylinders, and completely remedy them after intently performing a “power tune” to their outboards. Some of the older service manuals actually state you should do this every couple seasons, sometimes every season, to ensure proper piston ring performance.

[@GardnerHunts]

Awesome video! This was the fix to clean out the carbon buildup in the carb of my Mercury 115 2 stroke without actually taking off the carb, and cleaning it out. The motor now idles as it should and runs amazing!

I did the same thing earlier this year, before I saw this video, on a 2001 50 HP Yamaha outboard on the trailer with muffs. I also sprayed the carbs while it was running. Then, I let the Seafoam sit in the carbs for a week before running the second half gallon through in the same manner. Engine now starts easily for the first time since I've had it, and it runs beautifully.

Seafoam is the best fuel additive…I use it in everything I own. Saves a lot of heartache

[@petersouthernboy6327]

Everybody: don't be afraid to rebuild your carburetors. Use the factory kit, not the aftermarket kit. If the motor is really old, replace the carburetor floats also - they absorb fuel over time.

[@noway57]

Not a bad solution instead of doing all that if your not sure. Spend $7 on a can see if that solves it. Not everyone is inclined to do all that. It's more work than you think

[@jessebenitez6885]

@noway57 the older floats in the carb become brittle in some motors and end up clogging/ flossing the carb at the same time. Carb rebuilds are VERY basic and very WORTH IT as well. This video is also a great way to clean out carbon. Easier but not the only easy fix

A typical carb clean will do fine...carbs don't collect carbon..thats on the exhaust side of combustion...all its doing is cleaning the air and valve ports in the carb body...same as can be done with simple carb clean.. Ethonal doesn't hurt a 2 stroke it's the absorption if moisture it accumulates when not in a sealed system...and also the fuel lines needs changing on most old models because of cheap lining separation and then crumbling up and clogging up the carb...also it'll gell up in the bowl if left to long ... I tell all my people not to buy more than you'll need for a trip out if your not going regularly because of the gas going bad so fast these days...on the positive side of ethanol added is you don't have that pre ignition cladder climbing hills in our auto's... Some ask what is ethanol ? It's corn licker...pure dragster fuel...lol...

[@JohnJohn-wr1jo]

Seafoam is a great product, I reccomend it with every tank diluted vs the treatment process. Especially when you burn ethanol gas. I've never been a fan of shock treatments for an internal combustion engine and the fuel delivery system. It may even the idle out but its not healthy for the engine long term. I've seen too many engines require major overhauls long before they should who wait and use this product vs maintaining the cleanest system possible.

[@ChrisBeardsley]

so how do you 'catch up' if yo have an older engine and want to start treating it? IMHO you do need to start with a few heavier duty treatments.

Can you provide more information on how you connected the other tank... most primer bulbs I’ve seen have crimp connectors, so where do you disconnect it?

[@PrestigeWorldwideFishing]

I disconnected the fuel line coming from the motor at the existing bulb (cut clamp off with crimpers). Then I removed existing bulb and line going to tank. Next, I took the new bulb and line I purchased from amazon (link in description) and removed the clamp and line from one side of the bulb. Now, you have the existing line coming from the motor connecting to the new bulb and line going into 1 gallon tank. I didn't re-clamp anything for the shock treatment, but after done you can reattach existing bulb and line or leave new line on there. I purchased crimp style clamps from amazon to re-clamp everything. Here is a kit amzn.to/2F6fbpS if you don’t already have the crimper tool. Zip-ties also get the job done, but don't last as long.

[@PrestigeWorldwideFishing]

Not sure how your 2 stroke works but mine injects the oil into the gas and others you have to mix the oil into your boat gas each time you fill up. Might have to do some searching on how yours works. You don’t need to pour seafoam in your gas every time you fill up but a few times a year is a good idea. Also, Make sure you use 100% pure gas, no ethanol. Ethanol will tear up your motor over time. Email me at [e-mail] if you still aren’t sure and we will figure out how it works.

Jes there is Fuel problems we all get in outboards because of poor quality fuels with water and ethanol in fuels and lower octane. We dont get Seafoam in South Africa. Im going to try to order on Amazon and do some tests. There is a KZbin video that tested Seafoam on 4 stroke engines and it really cleans the combustion chamber and intake runner. Valve seats.

[@PrestigeWorldwideFishing]

It really does clean well, but also loosens things that can get caught in fuel lines and filters. I make sure to replace those after I do a shock treatment. Overall I’ve been impressed with seafoam

[@bipedalhominid6815]

If you want to clean all of the fuel ports you need to run it at WOT as well as lower idle speeds

[@Cripstobal]

Forgive me for my ignorance but what is WOT

Hello good Sir, Is that a 2 stroke or 4 stroke? Much obliged for any help.

Hi! It’s a 2-stroke motor.

Sounds good. Appreciate the speedy response...

[@Thedadjokedude]

Does this work for your exhaust? My exhaust is built up with carbon and won't go full rpm because of it and I was wondering if this would fix that so I don't have to take the foot off? Thank you

[@dougontheotherchannel3078]

no, SeaFoam does not survive combustion. CataClean is a product that will help clean exhaust. it is designed to clean catalytic converters, but clean the entire exhaust system

[@h8troodoh]

You Can use SeaFoam as a decarbonizer.. pull the plugs.. and pour directly into plug holes then allow the Seafoam to drain through the exhaust ports.. let sit for a while.. plugs in, start er up and watch the smoke.. should do the trick.. good luck.

[@gasousman]

Seafoam is great. Wonder what using 90% Seafoam gas and a week or whatever of saturation would do? Thanks for sharing!

[@PrestigeWorldwideFishing]

Yeah I’m not sure how much is too much. I just know doing the shock treatment every so often always seems to help my boat

[@darryllee9190]

Did you put 2 cycle oil in the gas or did you run straitgas and seafoam

[@PrestigeWorldwideFishing]

I didn’t add oil since my is automatically injected. If yours isn’t you need to do your regular mix plus seafoam. Good luck

[@rickristeen5123]

i put some water up gas in my truck made it run like well not good .i put seafoam in and ran it for a good while. next day it made all the water in the tank go away. total fix.

Is this going to delute the 2 cycle oil? I got a Mercury 500 series 50hp thunderbolt motor want to clean it but afraid it's going to thin my 2 stroke oil too much. Suggestions?

[@PrestigeWorldwideFishing]

Not real sure. My 2-stroke oil is automatically mixed through a reserve. I would think you would be ok but can’t answer for certain

[@h8troodoh]

It's fine as long as you have the correct gas oil ratio.. You're good..

[@johnsimpson4099]

My Yamaha 175 Pro V didn't really smoke unless I revved on it..

[@gophucyorselph5179]

Here's a tip. The longer you let it sit between treatments the better. Letting it soak, is what really loosens up the carbon in the cylinders. I let mine set overnight between treatments and it ran better than new. Afterwards I pulled the spark plugs and you can see how shiny the tops of the Pistons were. They were they were black with carbon before the treatment

[@PrestigeWorldwideFishing]

Awesome! Thanks! I will give that a try

Great tip and makes perfect sense. Soak time is good.

[@oneofakindoutdoors]

would this maybe help with low compression if I have a carbon build up?

[@PrestigeWorldwideFishing]

Honestly not sure. It won’t hurt though. Good luck and let me know what you find out

[@joeycallaway3194]

One of a Kind Outdoors what did you find out? I’m having the same issue with my 90hp mercury 2 stroke

[@h8troodoh]

Yes.. stuck rings from low grade fuel or oil will accumulate carbon on the rings making them stick.. hence low or no compression..SF used directly in the affected cylinders will loosen and break up the carbon deposits.. good luck.

[@Cripstobal]

Would driving it around and shutting it off for 5 minutes work the same? My controls don’t allow me to rev at idle.

[@PrestigeWorldwideFishing]

Yeah, just make sure you secure your can of gas. Might get some people thinking you are on fire too 😂

[@tannercompton6173]

so I have 1985 mercury 150hp black max and looks like one cylinder isn't giving out compression. I have changed my spark plug and I'm getting spark on all 6. Can using using this seafood fix the problem? My issue that I have is when I give it throttle and it gets up to speed for about 7-10 seconds it Boggs down and then shuts off? any ideas on what causes that?

[@DustinBlodgett]

I'm curious for an answer too. My 1978 200hp Black Max does the same thing you describe. Plugs are all new, but I need to check compression, change fuel filter and pump and try this sea foam thing. Check my shorts, I am just in the beginning stages of getting this thing up and running after sitting for 10 years.

[@h8troodoh]

Likely a stuck ring.. I'd soak that affected cylinder with SF, overnight.. Then use SF in your fuel as normal.. give it a gentle run . Then try your compression again.. multiple attempts may ve needed.. but it's cheaper than a shop rate.. good luck

[@rudy1574]

When you add the seafood to the 1 gallon gas do you mix your oil in the to ?

[@PrestigeWorldwideFishing]

Kind of. My motor is oil injected and it adds it automatically through a reserve. If you typically mix the oil in your fuel I would add it

[@1RedneckCajun]

Can this technique be used in stern drive/inboard engines?

[@PrestigeWorldwideFishing]

I don’t know for certain but I’m not sure why it couldn’t. Seafoam is pretroleum based and safe for all motors. It is designed to break down carbon buildup in motor and exhaust.

[@h8troodoh]

Yes you can use it safely in All internal combustion engines..

[@irvineporras9631]

Mine did not like it couldn’t get it leave the dock ran great before beside sitting for 3 years so I decided to poor some of this stuff in I got a bunch of smoke and rough idle wouldn’t stay running after taking it off of fast idle ended up taking it out and pulling some of the fuel out and adding new fuel

[@PrestigeWorldwideFishing]

Seafoam is designed to break down debris in your system/lines. If you have ethanol in your lines this will speed up the process of cleaning those lines which can add debris to your gas. Sucks initially but good in the long run once it is all out. That’s why I recommend replacing lines, fuel filter and spark plugs after shock treatment.

[@earlprice7200]

Theres a product called Ring free..its made for 2stroke outboards and is more potent than Seafoam oz for oz....couple times a season I run properly mixed tank...keeps the carbon build up from happening 💯

[@PrestigeWorldwideFishing]

Can’t say for sure but I wouldn’t think so. It’s also used to run through your motor before winterizing it and to sit in your tank to help preserve gas. So I would think by design you should be fine.

The reason why you let it cool is because the seafoam actually sticks to the carbon deposits and then the next heat up it blows it out and the repeat of this speeds it up
