its a johnson! just buy the cheapest crap you can buy

Nautilus was recommended to me for mine, they are naturally a bit smokey, it's part of the charm

Considering WOT it does 42knots  and she gets 1.45km/l on the river maybe not at the same time, I'm not complaining.

Thanks Rig, who supplies Nautilus.

If you want to get technical and you are able to spend a few bucks I can give you some real good advice. For what you are dealing with I would just go with the prescribed mix of any reputable oil. It's like fishing mate.. why complicate it?

sorry i couldnt help my self after your post! i used nautilus in my yammy! good stuff

Well Vince,

I do believe you look after the heart of your boat and it will look after you. A few years ago, I used common, cheap 2 stroke oil in my outboard and guess what? Dropped one of the big end bearings in the middle of the Brisbane River. Whether the motor is old or new, cheap or expensive, at the end of the day, if you don't treat it right it will cost you big bucks  to fix the bloody thing if you're lucky to get back!!

I can't say I disagree with you on that. Being a car mechanic myself, I do look after my own vehicle and have researched different fuels and oils for CARS. But boat motors especially two strokes are a different kettle of fish. They therefore need a completely different breed of mechanic. I am not an outboard mechanic and I really would not want to put my family at risk doing work on it just to save a couple of bucks now, to have it stop in the middle of nowhere.

The guys at Repco are basically parts interpreters. You may be lucky to get one old hand that has been in the game for many years but they are rare like Dave at Joondalup. He would tell you as I would there is only one brand of oil to use in your type of vehicle and that is Penrite. It is by far the best quality and this can be seen at every oil change. You're right the fuel we get over here is basically some form of BP since that is their refinery down south. The only one that guarantees their fuel is BP and the only fuel to use is their 98 fuel. It is the only fuel that does not make my car's 5.7l run rough. And yes, it does give it much better fuel economy than regular.

2 strokes are usually running at high revs I certainly like to know I am using good oil in mine as you also premix your fuel your dont want any crap building up in your carby. Shell make nautilus David and I also agree about the fuel. Only use premium fuel in your motor it will run alot better, I find mine splutters and runs rougher on regular unleaded

As I said, I am a car mechanic not a boat mechanic. The only similarity is that they are both internal combustion engines. They use different techniques to lubricate the engines and the climates they run in are critically different and therefore they have different mechanisms to overcome those differences.

Vince, basically what I am saying is that I don't know the true ins and outs of two strokes. Any auto mechanic who does and has not been trained in marine engines is not only fooling him or herself, they are putting themselves and others in potential danger by having a motor that is not up to the standard to be able to operate in the severe conditions that the sea can put up.

And Rig put up another argument about crap building up in the carbies.

You can definately notice the difference between crap and quality 2 stroke oil .I use to run yammalube oil in my 90 johno and it hardly smoked , on a long weekend I grabbed some other crap from a servo and it smoked like a bastard .The yamaha oil is also decently priced . I use to pay $168  for 20L .

You can make up your own mind though. Use different oils and check how much soot is on the inside of your prop after flushing the donk .

Joel

Yes Joel,

I know what you mean. There is quite a bit of soot on the inside of the prop. So you say Yammalube oil is the good oil? I will give it a try after this batch of Canadian oil I got from Rottnest a couple of weekends ago.

I worked for Caltex for many years they made the oil for Yamaha and merc using the same base oil as there own that oil came from Bp in kwinana they used the same additives in all of them just different containers same as fuel all comes from Bp in kwinana

Didnt realise I was argueing there. You asked which oil and I told you the one recommended to me by 2 boat mechanics I have taken mine too.
Grease monkey I hope you werent referring to me as a 2 stroke hater, if so you probably can't read hey?

Rig ,I wasn't referring to you . Probably poor choice of wording when I said 2 stroke haters .

Tomcat , thats pretty interesting . Which merc oil is the same as the yammy oil . I am guessing that it does not extend to the DFI oil though. If so that would save some of the DFI owners a fortune . Mabey you could list all the oil that are the same for us . 

On a lighter note , every time I use to buy the yammalube the bloke at the shop use to say

"Like feeding caviar to a donkey " and piss himself laughing .

JOEL

Haven't worked there for over 10 years most oils are blended over east I think BP still do it here only thing I saw different was the colour of the dye

Like XD 50. I have a Evinrude ocean pro 150 and used yamalube, Good oil but still smoked heaps. Changed to XD 50 and a lot better. Nulon makes a semi synthetic and sells it through super cheap auto, And all boats sell a sierra brand semi. Stay away fromfull synthetics i  read somewhere that full synthetics are no good for older 2strokes causes the pistons and bores to score semis are fine. The only problem with XD 50 is finding a place that sells it.

So you said that you had problems finding a place that sold XD50, but did you finally find a place or did you go with the Nulon brand?

By the way, Vince, I hope I did not offend you the other night. I wasn't having the best day and I may have taken out on you. I am sorry if I did. All opinions are valuable as far as I am concerned, and that is why I am a member of this forum.

Sometimes, ladies and gents, what we get to power our boats may not be what we want but what we can afford at that time. Presently, I have a 2 stroke and later if the financial controller lets me I will upgrade to maybe a four stroke or even an Etec. But for now, I have this and I am sure, there are others who are in the same boat (not literally) as me.

 is the go
