To fog or not to fog OX66 250hp

[cobrapowersys]

It's a 2 stroke so the oil is added to the fuel for lubrication and is burned off. No oil filler/filters. An OX66 mixes the oil/fuel in the proper ratio using a separate oil pump at the oil tank. Only use Yamalube 2 stroke oil, in my opinion.

You should really read the manual cover to cover and then read about these (expensive) engines on line, otherwise you could be looking at some serious repair costs down the road.

BTW- I like the tip on using a string to pull the landyard off to kill the engines! Clever....

Thanks Max! That was my suspicion but I wasn't sure. Is it wise to change the 2 stroke oil even though I use about 1 gallon for every say 6 or so hours of use? Running at about 3/4 throttle...

Max , is the oil pump a part that needs to be replaced after so many uses? Obviously a very important part as to keep the oil running (1) and (2) the proper ratio should be always maintained...

I used to fog my old OX66s (one at a time) by spraying the fogging oil in the throttle bodies (alternate a few seconds on each) while at a fast idle. Could never get the engines to stall out no matter how much oil I hit them with. So, I just got in the habit of tieing a string to the stop lanyard and when I felt they were good and loaded up I would just pull the string and kill the engine. Then I took out the plugs, shot a little oil into each cylinder, coated the plugs, reinstalled the plugs and hit the key for a second to distribute everything.

Those darn things started better the first time in the spring than they did for the entire rest of the season...

Thanks GW!

this is what i have now do you recommend upgrading brands etc??

Just make sure your water seperator is a 10 micron type.

This may seem like a dumb question but does this motor use Standard Motor oil and oil filter because if so I do not see a fill port or a filter

OK, now you must be pulling my leg
If you don't know aht type of oil or where it goes, then you haven't added any in 3 years and that is really hard to believe.

That's right! now are you going to answer my question or are you going to continue being a condescending d*ckhead like you were from the start of this thread.

I went back and re-read seasicks posts and didnt see ANY Condescending remarks..You asked about standard motor oil and filter in a 2 stroke..now if you just bought the boat and havent used it yet and no NOTHING about engines thats one thing,,but you had the boat 3 years. What oil have you been using and where have you been putting it?? There is a 50:1 ratio(for every 50 gal of fuel the engine will burn 1 gal of 2 stroke oil) im sure in 3 years you went through at least 200 gal..about 4 gal of 2 stroke oil....
