I run a 2s but still watch to gain knowledge. If I may offer a helpful hint, instead of using a rag when removing the filter, put a cheap disposable baby diaper under the filter.

If you ever get yellow foamy oil it can be overfill. Was struggling to figure out what it was until he talked about over fill. This is what I just had. When checking the dip stock oil was gushing out from the dipstick on my 30hp Tohatsu 4 stroke. Oil looked good but after running it went yellow and foamy and got oil light. Previous owner must have over filled it, maybe as a storage precaution I don’t know.

[@TheGreenbeanhead]

[@zlvirag]

[@Modafinil]

Honda BF 30 (2005 model) has its oil filter much lower and it is very difficult to prevent oil from leaking to the lower cover of the engine with just using some rag under the filter. Last year I tilted and turned the engine some times after I had originally emptied the motor oil from the main plug. I think there was less oil in the filter after these steps but it was not empty from oil exactly even then. However, I did, when the warranty was valid, take the engine to the professional service. And there was never any mess of used oil in the lower cover. So there must be some tricks on how to do the job cleanly even when the oil filter's position makes it difficult to apply a rag compact enough...

[@aaronwildeofficial]

I change my (Yamaha 9.9) oil using a syphon pump into the dipstick hole because the boat's always in the water. I tend to do it cold, my theory is that the cold oil will actually suck up better than thin oil, especially the last little bit. Thoughts?

[@DangarMarine]

It is very common with boat to suck through the dipstick hole. I personally don't think it will make a huge difference whether it is hot or cold. By the time you add a couple of litres of new oil and run the motor with a new filter it will be mostly clean.

[@roughas100]

Did an oil and filter change today on my 2014 Tohatsu 50hp , previously had a HF199 oil filter ( changed in 2018 ) but bought a Z436 after seeing this video , these 2 filters look practically the same , the Ryco Z436 cheaper and easier to source and about 1/3rd the cost of a genuine Tohatsu filter....... Have used automotive engine oil before , seems to work fine but this time I put in Gulfwestern FC-W outboard oil 10w 40 , I could be wrong but think they have some extra anti wear additives eg zinc that are beneficial for 4 strokes with no catalytic converters .

Hello. Which manufacturer is the engine oil used and with what viscosity?

[@bobbuilder5362]

Good vid. Always wondered about the automotive verse marine oil. Likely little difference ?

[@DangarMarine]

The claimed differences are corrosion protection (I've never seen an outboard rust on the inside unless it has a blown head gasket) and being slightly tailored to the fact that outboards run at high RPM for long periods of time. My old Toyota ran at over 4K all the way up the freeway home so I don't see how high quality auto oil isn't up to the job.

[@ronpowell2373]

One for the Australians- look up what the numbers with oil actually mean. Australians rarely would be running an engine in sub zero conditions so 10- or 20- oils are fine for our conditions. My car engine manual states to use 0-30 but I run it on 10-40 in winter, 20-50 in summer. I may lose a little in fuel economy but in our heat that extra viscosity is valuable off road and working hard ( turbo diesel) to stop metal touching metal. I also seemed to have less issues with EGR valves compared to the guys I travelled with . As for my outboard- I now run Tohatsu 50 TLDI and so the oil is a total loss ystem .

@@DangarMarine that would be awesome. Thanks

[@hobbyaddict9908]

I always at least partially fill my oil filters.

[@stanpatterson5033]

I do too. But in defense of this practice, and in support of those who don't, it can be tough to get the partially filled filters on the sideways mounts without losing some and making a mess. The secret I've found to avoid spilling out of a pre-filled filter is to keep it spinning no matter what. If you can keep a spin on it, centrifugal force keeps the oil against the wall of the filter. It's a bit of a trick to master, sort of like spinning a basketball to keep it on your finger tip. I don't mean you have to spin it so fast that it's a blur, just keep it rotating so that the liquid level in the filter won't make it up to the center hole and puke outward. The oil being cold and thick helps with this.

[@DangarMarine]

Be careful prefilling as any debris in the can will enter the engine without having gone through the filter and can cause serious damage. You won't ever see a professional shop prefill an oil filter. As further evidence that is isn't necessary the oil filter for the truck in the background points straight down so it just isn't possible at all!

[@hobbyaddict9908]

@@DangarMarine I assume you mean the oil can? I use one litre bottles that come sealed. If there is anything in there that is not supposed to be it will end up in the sump anyway, Please, I am not complaining about your method, just stating my own. I am a licensed auto mechanic and have always used this method to avoid running the engine "dry" for as little time as possible. Back when we used conventional oil only we were doing oil changes VERY often and if the engine ran dry each time it "could" take many miles/kms off the life of the engine. On an outboard that perhaps only has its oil changed annually the difference would be negligible. Similarly when I rebuild an engine (4 stroke) I disconnect the ignition and crank it until the oil pressure comes up, then reconnect the ignition and run it. As for your truck, yes of course it would be quite impossible to prefill as it is in many of the newer vehicles using replaceable cartridges instead of spin on filters. However many of these newer vehicles also recommend synthetic oil which has better retention properties than conventional oils and will stick to the internal components better thus keeping them lubed longer. As with many things there is no set rule for ALL situations. This is indeed one of them. Again, I am not suggesting your method is wrong, just that I use a different method.

I find most marine mechanics around here to do that, and I do too sometimes. Most of the guys around here are doing the service on their slipway so it stops oil going into the water too.

Ive had a Tohatsu 25 4stroke sit for a few years (it was winterized correctly). Should I flush it? What type do you use?

[@DangarMarine]

I wouldn't be too worried. We use a Wurth engine flush.

My Yamaha F150 has always ran Yamalube Conventional and currently has almost 1300 hours, would there be any concern switching to a fully synthetic oil? Ive heard it may cause oil leaks or oil burning by removing carbon deposits that have closed clearance gaps. Id very much appreciate your opinion on this!

[@DangarMarine]

You can definitely have problems with anything that will clean an older motor, that's true. Also, don't go full synthetic as it tends to absorb water when used in a marine environment.

[@ThePulzeGamer]

I need to service my little honda 15hp which runs in fresh water only , so normal automotive oil will do aslong as its the right type for the engine ofcoarse ? :) , need to do full service before i cause any damage haha

[@DangarMarine]

Yes, auto is fine but as someone mentioned below don't use full synthetic.

[@ThePulzeGamer]

@@DangarMarine oh okay thanks mate

[@kookoo123100]

Hi Stu love your videos mate. I have a Yamaha F50 four stroke that needs a service can you do it for me?

[@DangarMarine]

Thanks mate. I don't do services for people but the Yamaha dealer down in Brooklyn is very good.

[@mareksokalski9933]

Help me please. My Honda bf75 1996 working just 2 cylinders. I check coil is ok . Spark is . Spark plugs change.

[@andybowlin]

Automotive oil works fine then? Mobil 1?

[@DangarMarine]

Don't go full synthetic, it can absorb water.

[@handleismyhandle]

Wish I had realized that running an outboard (yamaha 50) that had been stored improperly would cause hydrolock due to oil in cylinders and apparently major damage. Oil was forced out PAST plugs. Cleaned carb very thoroughly and replaced sparkplugs after doing shock treatment with yamaha carbon burn off chemicals and engine is still running very rough at low rpm, smoking, and only pushing boat at 1/3 speed. I am guessing that my next steps will be doing a compression test, making sure exhaust pipe is clear, and checking valves, and most likely I will end up referring to your videos for a total rebuild and replacement of con rods. In case you read this, is there anything else I should know at this point? At least the advantage of having a motor that was questionable before my incredibly stupid act is that I can assume basically everything is broken and use it as a free (sort of) college course in mechanics.

[@DangarMarine]

Unfortunately there is a chance a con rod was bent if it hydrolocked. Not much you can do about that other than rebuild. I wouldn't expect residual oil to take more than a few minutes to burn off completely.

[@davidsledz5711]

Anyone have a link to that oil filter removal tool used?

[@DangarMarine]

It is a SnapOn tool, but not sure of the part number.

Hi i have a 4hp 1999 johnson outboard motor and when i give it full throttle it doesn't open up properly but at slow speed it works perfectly fine. I cleaned the carb and the jets already and changed the fuel filter but still no difference. Can you please help me?

[@DangarMarine]

Could be a problem with the timing advance or the throttle plate not opening properly.

[@andrewabela1531]

Hi thanks for your reply. The throttle plate seem to work fine i think the problem is more about fuel but i changed and cleaned everything in the fuel system and still no difference.

[@outdoorisbetterdh.]

Hope you can read my comment and gave me some idea 💡, I got engine outboard 1987 mercury force i was testing the other day and I found water leaking by my spark plug 😆 yes from my spark plug, I don't what to do really isn't much marine mechanics around me,when I connect tho water on land and I start the engine water start coming out my spark plug ☹

[@Fireship1]

No oil to change on my Yamaha two stroke. Well, I’m all set when I upgrade the two stroke to a four. Oil changes will be a breeze now!

[@DangarMarine]

You never know what the future holds. :)

Great video, do you recommend changing the oil at the end of the season before putting into storage, or at the start before using the boat for the year, in Wisconsin USA so the off season is pretty long, about 6 months or so,

[@DangarMarine]

I would change it before the end of the season so it sits with clean oil in it for the winter.

[@josepthomas96]

Got a 2008 bf50 second hand idels perfect compression is 135psi all 3 cylinders carbs are cleared up. can't push the boat pass 8 mph any idea sorry can't bring it to u for service I'm from Canada .boat is 17' aluminum

[@arciefan]

Hey Stu, Excellent video. Don't know if I wish I had a 4 stroke more or just an electronic fuel injected two stroke. I'm still in the carb business. Thanks again!!!

[@DangarMarine]

They are both pretty good these days. I like four stroke for not having to remember to have two stroke oil on hand but then again I use the boat more often than the average so it may not be such an issue for fishing boats.

[@francisoconnell7913]

Hi danger i have a 50hp 4 stroke 2006 outboard enging i want to change the oil but the sump knut is rounded and cant open it can you please help

Yeah, bought that one a bit over a year ago now. Really loving it. :)

[@lukestrugnell]

Thanks for the video. One question on the engine flush. Don't modern oils have enough additives in anyway to clean and reduce sludge build up etc? Is it really necessary to do a flush? Mainly wondering for my Toyota Hilux more than an outboard. Thanks mate

[@DangarMarine]

I wouldn't say it is strictly necessary as modern oils are definitely better these days. It's more a case of showing that the option exists.
