[Looks like I am on the home stretch. Just doing the small fun detail work this weekend. All polished up!

I believe there is another section in the Mercury service manual that covers oil mix ratios for the older 25:1 motors. My manual is at home but try under 4 cylinder motors like the Mark 58, 58a, 35a, and 400.

Thank you Ray, Joe and john for all of your time and thoughts on this subject, I have learned a lot about oil ratio mix.

Clear as mud! :tongue: :goof: just kidding...

Thanks to Joe for the very detailed post regarding oil mixture ratios.
This is a subject that will often start a long and nuanced discussion on nearly any outboard forum.
My definition of "running a motor hard" is also high RPM operation, I prop my OMC loop charged motors to run 6,500 to 7,500 RPM and I will usually spend some time in those ranges any time I am on the water. I bought my 1998 50 HP OMC new in 98 and it has been run under those conditions extended hours every summer of the last 20 years and still going strong. The original operators manual and service manual both recommended 25:1 during break-in and if the motor is operated at the limit of the operating range which they put at 6,500 RPM.
Keep in mind 50:1 is 2% oil and 98% gasoline, 25:1 is 4% oil and 96% gasoline, double the oil but just a 2% difference in over all concentration.
My experience with early Mercury's is very limited compared to Joe's.
There are forums dedicated to the old Mercury's that have a depth of experience and expertise that I would recommend to anyone who is running one.

Hello All,
I wish to first state that I wish this to be helpful, and in no way do I wish to "down" anyone who differs in opinion with me. Further, I feel that since I literally grew-up in my family's marine business (a Mercury Outboard dealership for 50+ years), I do feel I am well qualified to offer advice on this subject.
I would personally define running hard as either significantly exceeding the manufacturer's recommended engine RPM, or operation in harsh conditions (extreme cold or such). My father's racing outboards were said to "turn" 8000 RPMs, so this would certainly be "hard" operation to me. Next, a discussion of other brands of outboards other than Mercury well might need to also consider the type of bearings utilized in the "powerhead", but all Mercurys except for the very earliest models feature ball, needle, or roller bearings for the crankshaft, crankpin (connecting rod to crankshaft), and piston pin (connecting rod to piston) applications, so the usage of currently available "50 to 1" and synthetic "outboard motor" oils with most all vintage Mercury outboards is not as a big concern that most other vintage outboards which may/do have "bushing" bearings for the piston pin, crankshaft, or crankpin applications, and would definitely then be of important concern.
A Mercury service bulletin from the 1960's states that Mercury did extensive testing of their then new 50-D (50 to 1 recommended ratio) oil on older (now vintage) Mercury outboards, and recommended it's adoption/usage. As to a "little is good, more is better", one has to begin to worry about carbon deposit build-up, especially in the piston ring grooves where the piston rings install. With greater amounts of oil, greater amounts of carbon is produced, and when the carbon is deposited between the piston groove and the piston ring, the piston ring can no longer fully "retract", and is instead "jacked". Most all 2-cycle (2 stroke) outboards outboard cylinders have holes or ports for intake and exhaust, and when the piston ring is "jacked" to enough extent, the piston ring(s) will "catch" a port, breaking them, the cylinder, or both, creating engine failure. One must either utilize a very high quality oil which "leaves" smaller amounts of carbon deposits, or instead a dispersant must be at least periodically induced to allow more of the carbon to be expelled. As to "oil is oil", and purchasing the lowest cost oil would then seem wise to do, but typically, outboard manufacturer's branded oils will have an improved additives "package", and these additives are far more costly than the "base" oil they are added to. Dispersant, or the amount of dispersant, included as an additive is therefore very important. Otherwise, it must then be periodically added to the gasoline and oil, or induced into the cylinders to help dispel carbon. Semi-synthetic or fully synthetic oils typically "leave" less carbon, but again are more costly. For a Mercury outboard (other than the earliest 1940's models - models produced before World War II), much more than 40 to 1 personally seems unwanted/unneeded within/very near of the recommended RPM limit, and within recreational usage, WITH the usage of a high quality outboard oil. Certainly I would recommend an outboard manufacturer's brand oil, but other brands which are semi or full synthetic may be excellent choices as well. IF however, another brand of outboard is the subject, and it has bushing bearing(s), the use of a 50 to 1 ratio is then seemingly unwise, and a greater amount of oil (to the amount of gasoline) is needed. For a long stored/dormant Mercury or another brand outboard, it will likely be wise to utilize a greater amount of oil for a tankful or two to better protect against cylinder rust which may have formed. Significant rust however cannot be "solved" with a large increase in oil, and instead disassembly is required.

Regards,
Joe (MercurySpecialist)

I think you are looking at oil mix ratios for engines that are designed to run with a 50:1 ratio. I would look elsewhere in your manual for motors that are designed to run at 25:1.


Thank you john for your replys. I did talk to Joe Poole today in regards to this manner. " Mercury specialist" on the site.
The "new and improved Quicksilver 50" oil as referred to in the manual, Is design to run 50:1 as your previous comment 25 to 1. For break-in you are correct John.



I would make sure I had that at least for break-in and maybe more, oil is cheap. If I planed on running the motor hard much I would run more than 50:1, I run my motors hard and run about 35:1 unless I'm going to be running with Dan and that off brand sleeper motor, then I run 25:1
