2stroke yamaha outboard oil mixture ratio?
541264
there are different ways to do the mixture, all depends how hard do you ride, the easiest way is, mix 12 onz. of oil into 5 galls. of 91 0r 92 octane of gasoline, that should be good for easy or kind of hard riding

Check on E-bay, they have a few similiar vintage models you could compare "going" prices on. Also if it runs and you are close, i'll buy it. I need a motor for my fishing boat.

uses more oil quicker. i stuck on the question please explain more

For a while Yamaha built motors for mercury, up to 15 hp. They are pretty much all Yamaha. I've had one of those since '81. I am a teacher and spend the summers (all) at the lake. I have never had more than two pulls to start the engine and have ZERO repairs. When I bought a larger bass boat in '99 I bought a Yamaha for this reason. I'd say it is better than a mercury, especially if it is older since there were issues with many older Mercs. I mine often as does my son.

I used to have a blaster and they recommend that you use 30 weight oil.

http://energy21.freeservers.com/bookrep.html  Want to know something else? I've found a way to convert gasoline into Propane! And it can never be marketed! All Engines from 1996 on up must run at an Air to Fuel Ratio of 14.7 Parts of Air to 1 Part of Fuel! My System goes 100 to 1 Air to Fuel Ratio, but it will never happen! You want something interesting to Research ? This is it!

It`s an oil injected 2-stroke that you must use an injector safe 2-stroke oil with, or it`s a 4-stroke with a dry sump system which has an oil tank.Unlike a wet sump 4-stroke where the engine oil is poured into the crankcase.If it is the 4-stroke dry sump system you should try to get yourself a manual for it so you know how to properly check the oil level due to the fact that most dry sump motorcycle engines require that you let the engine idle for 5 minutes (without revving it up at all) in order to get a proper reading.the honda trx 400ex,and the honda aquatrax watercraft are a couple examples of this.\n  OK to tell wether or not it`s a 2-stroke or a 4-stroke, if it has a plastic tank for the oil with 1 rubber line running from it to the carburator, or somewhere real close to it, like the intake manifold, then it`s a 2-stroke.These usually wont have a dipstick either.\n  If it has 2 lines with metal fittings and a banjo bolt with a crush washer on both sides of each line it`s a 4-stroke wet sump engine.this is not to be confused with an oil cooler that will have 2 lines and same fittings but go from the engine to what looks like a small radiator without a cap(which is essentially what it is).\n  One other tell tale is how the engine sounds if it sounds like a chainsaw it`s a 2-stroke.If it sounds like a riding lawnmower it`s a 4-stroke.\n  Also a 2-stroke exhaust pipe will get alot bigger about 5 to 6 inches after leaving the exhaust port.By alot I mean it will go from a 1 3/4 in. dia. to 7 or 8 in. dia.  and then taper down to a small dia of approx. 3/4 in. dia.\n A 4-stroke pipe will be the same size dia. all the way back to the muffleron a single cylinder, or to where the individual pipes of a multi cylinder engine come together then get slightly bigger before the muffler or megaphone on old inline 4 headers like Kerker or MAC .\n  Hope this helps.

It just depends on what your going to do with it. If your going to mud ride alot I would say get a 4x4 standard 400 Honda rancher they are tough but not the fastest. If you want fast get a like a yamaha 4x4 400 Kodiak they are fast, or faster than everything I have rode in its class. Every Polaris I have seen or rode either had a super bad resale value, or it broke. Suzuki's are ok but the fuel mixture is to rich going to the filter I have found in the 4x4 400 eigers. So its basically what ever you want to try.

depends on the stroke of the engine, call a boat shop or one that works on outboards they'll know\n\nyou can really jack up an engine if you dont mix properly or do when you shouldnt\n\nask a professional
