7 posts in this topic

I have a question. I have a 96 90hp evenrude. my question is this. Do I have to use the omc oil or can I use the oil sold at wal mart?I think if it has tw-3 it is ok to use. Am I right or should I continue useing the omc oil. Don't want to damage thie engine.

Use a major brand TC W-3 2 cycle oil and you will be fine.

thanks Bruce. I think I'll stay with omc oil, not worth blowing a motor to save a few bucks

I used tcw 3 for years and finally blew the motor. Stuck a ring I believe it was from excessive carbon deposits after tearing into it. I would use premium non ethanol fuel and amsoil to help prevent this. Also make sure you decarb the motor at least once a year. The amsoil will help get rid of the smokescreen the old evinrudes are famous for.

FWIW, the Merc Quicksilver PRemium Plus oil contains small amounts of what merc calls QucikClean (I think that is is it, their decarboning agent) so you never really need to do a big "treatment" of decarboning. Otherwise isn't the Yammie product called RingFree that is a real popular product, that I think many people use.

Our 82 merc 50hp has only been fogged like twice for storage, we stopped doing it cause it was always a bear in the spring to start after fogging, but we only use Premium Plus and it is running strong after many hours - now it usually only gets used a lot in spring and then a ton during duck hunting season. And we have never really done a "decarboning" except using Prem. Plus... Not sure if that is advised, but that 25 yo motor is still as strong and reliable as when it was new.

    • Money to be made, and the cold war (you remember the cold war, right?) was the reason we did various things.    Go read about Stalin and his successors to see why we were worried about the Soviet Union.   What we did might or might not have turned out like we hoped but that doesn't change what the situation was.   
    • Dave, your economist wants immigrants to meet requirements like posting a bond or having assets.  Why should they do that when they can just come in with nothing through the porous borders?   Isn't the argument about open borders vrs controlled immigration?   Would the 11 million undocumented have to go back home and post a bond?     If the US through its political process decides to allow immigrants, that's cool.    But that is not what we have now.   Better pick that mike back up.  
    • I'm still trying to figure out why we pushed the coup in Ukraine, other than to cause trouble of course.
    •   Ditto, almost exactly the same. I wouldn't spend a ton of money on decoys if your just starting.
    •   To tell you the truth. I have never cleaned a cottontail ever that didn't have flees all over them in the winter. So I just stop hunting them and went for Snowshoes which are bigger and never found flees on them, oddly?
    •   Seems the hares are down from when I was younger but the cottontails seem plentiful enough. I popped these with a 20 gauge shotgun while grousing
    • I use to go for Snowshoes a lot in the winter with a scoped 22. It was fun sneaking through the pines looking for them. See the little black eye and "bing".  Seems like they just fell off the face of the earth for many years so I just gave up trying for them. I'm sure with the big "Down with Fur" thing and not many taking out as many Fox and Yotes by trapping it really took a hit on the bunnies!  I wrote the DNR back a few years ago and asked them about it and he said: we really don't manage the Rabbits at all. And he gave me the old "Grouse BS". Their just at the bottom of their 10 year cycle!   Seems to always be their answer!
