I am new owner of a 9.9 and not very familiar with the motor. what type of oil do I mix with the fuel at 50:1 ratio. every place I have turned gives several different kinds to use. which one? please bear with me I am new to this motor and have lots to learn about taking care of it.

Only use Johnson outboard oil.----Will have TCW-III on container----TCW----- I believe is for Two Cycle Water cooled.
 
I have extensive experience with the 9.9 and 15 hp motors. I have rebuilt many. Everyone gets a free quart of 100 to 1 Amsoil fully synthetic pre mix with their repair. We also have 2 camps in remote NW Ontario. I mix 64:1 with non oxy fuel. Also give a full 1 year warranty with ALL my repairs. Been doing this since 1977 when I got handed my very first case of Amsoil 100:1 2 stroke oil.......by the owner and founder of Amsoil, Al Amatuzio......a close family friend and retired Air Force fighter jet pilot. The Amsoil plant is only the neighbor town to Duluth, where I live. This oil far exceeds OMC, or any 2 stroke oil specs. Amsoil is the very first in full synthetics. If everyone used this oil, we probably wouldn't need 4 stroke outboards. Al just died recently at the age of 92, but his legacy is supreme. If you damage your outboard from my recommendations, contact me privately and I will overhaul it for free. Just ship me the powerhead.

Amsoil is good stuff and no complaints with my past experience. But, I've had good experience using Evinrude Premium 2-stroke oil in my '79 9.9HP. I get this at Walmart for $19/gallon and it lasts me quite a while. This is the mineral based, red colored oil and I think it's identical to Evinrude XD30. I get virtually no smoke with this oil, the engine runs smooth, and I have no oil fouling on the plugs.

Also, a good practice when you get a new motor is to drain and replace the gear oil. You don't know how long the old stuff has been then so it's best to start fresh so you have a known point of age. I use BRP HPF PRo oil because I keep a gallon in the shop for use in my 150HP. But, BRP HiVis or just about any small outboard gear oil will work fine in the 9.9. The main thing is to have good, clean oil in the case.

When you drain the gearcase, be sure to remove ONLY part #30. This is the drain plug with a slot requiring a large flat blade screwdriver. You'll seen an identical one just about the anti-ventilation plate. DO NOT REMOVE #14. This is a phillips screw head that is the shift pivot pin and creates HUGE headaches if you take it out.

Have you ever owned an outboard before and know how to drain and fill a gearcase? If not, let us know and we'll give you the method. IF you have, then it's off to the races.

Excellent information for rumtum. I have a serious problem with some of OMC's ideas that over time destroyed millions of outboards. AccuMix and VRO's. Why anyone would ever place an OMC recommended oil over and above the best synthetic 2 stroke oil on planet Earth......is far beyond me. In over 40 years of resort operations, personal experience, and repairs WITH WARRANTY, I have yet to see a failure due to proper use of Amsoil fully synthetic 2 stroke oil. This includes chain saws and vintage 2 stroke Ski Doos.

The old 100:1 mix recommendation was definitely a nightmare for OMC.

Personally I like the VRO on my Evinrude 150 and I have auto-oiling on my Polaris PWC's. I like the convenience of just fueling up and going. On little engines like the 9.9 using pre-mix is no big deal because they use very little fuel. The 150 and PWC's drink fuel like Otis the town drunk on Andy Griffith. I'd go crazy keeping bottles of oil handy and mixing every time I filled those tanks if I didn't have the auto-oiling.

Rumtum, I'd also suggest you get an oil mixing bottle like the picture below. They are marked for everything from 24:1 to 100:1. The bottle is cheap and gives you confidence your getting the correct mix for whatever gas volume you're filling.

Kevin, your advice is solid, its refreshing to see someone with experience in this trade, that is open minded. Sure, there are plenty of VRO's still in service........the general idea is brilliant. The defect has been a default configuration that factors in a lack of oil upon certain failure. Ethanol was being implemented during production of VRO's, yet OMC continued to provide units destined to fail. That is a tragedy. Had this knowledge been applied properly and VRO's reengineered to tolerate ethanol.....not just "resist" ethanol, hundreds of thousands of outboards could have been saved.

Any oil certified TCW-3 will be fine if mixed 50:1

You will find all you will ever need to know about the OMC 9.9s on Lee Roy's ramblings

Here is a 9.9 that a built from spare parts and converted it to a 15 hp. It has an automotive base/clear finish. Sold it for almost $1,400.

everyone thanks for the info, to answer some questions I don't have lots of knowledge of outboard motors. but I do understand the basic of a small engine. My affection for the 9.9 comes from my father who worked for Evinrude in Milwaukee for most of his life. they would let the workers sign out motors to use. so I got to see that 9.9 for many years even the folding motor. which I thought was so cool the it fit into a carrying case. as much as my brother and I begged my Dad to buy a motor, he always said he couldn't afford one. I even offered to give up my .50 allowance for a year to help pay for it. he would just laugh and mess up my hair as he rubbed the top of my head. I am sorry I digress to my childhood. I wish my father was still around to see that I finally got the 9.9 for myself. this motor brings back so much of my childhood memories.
thanks for Leroys information that man has a passion about motors. I think I have found a place if I need help I know where to look thanks again. and thanks from a newbie who docent know much about anything....lol

My little '65 Evy.jpgGreat. 50 cents allowance! Wow! Thats what I got. Back then you could buy 2 gallons of gasoline.....I mean REAL gasoline.....with lead, for that price. No wonder this new stuff doesn't last. I just passed up a folding 3 hp at a garage sale......estate wanted like 400 bucks for it and it had low compression. It was pretty nice looker, with case.....probably should have bought it. I never really left my childhood. Still collecting and repairing outboard motors. For me, youth is just a CD-12 away......1955 Johnson 5 1/2.
Just check with the forum, we won't steer you wrong. My dad loved motors too. He guided in Canada whenever he could break away from his radio station and coin machine business. He bought me my first motor to guide with, a 1965 Evinrude Fisherman......still have it, runs purr fect. Looks pretty. Leroy would be envious. Over 4000 hours on it.
 
Timguy and Kevin, thanks for the info about draining the gear case oil. from my reading it looks OEM XD30 would be what I would use. Since there was lots of talk about Amsoil I was looking at the HP oil and the Pre Mix 100:1 which was recommended by some. I think for the age of the motor I am going to go with the Pre Mix Amsoil.

You can run any ratio from 40 to 100:1. I have settled on 64:1 on most of my equipment. On motors I use exclusively for trolling, I go 100:1. Do what feels comfortable for you. Amsoil has never failed me in over 40 years of commercial use.
