Mariner 2hp 2m 6a1 Service manual and oil mix?

[brandenjg]

Hi everyone, I've just got myself a little mariner outboard and i was wondering what oil mix it needs. Ive been told that the factory recommended is 100-1 but after doing a search on google, alot of people are saying 50-1. I was hoping someone on here could tell me the right mix. I'm also looking for some sort of manual for the outboard for reference if i need to do any repairs or maintenance.

Im going to be taking it and the boat down to wells wednesday to test it out ( Mainly because i see no reason to buy the toll for the broads till i'll actually be using it after april)

As usual any help will be greatly appreciated.

Thank you

Hi,

I now have a 3.3hp Mercury which I will be using a ratio of 50:1. I should think this would suit your engine too. With regard a manual, I don't know if sending a PM on this link would be of any use to you?

(mods, sorry for cross linking to another forum, but I didn't think it's be too much of a problem in this case)

Thing is, dependant on age, it could be either, but running it on 50:1 will do no harm especially if you are running it at high revs. As for the manual, as these little ones are all basically Tohatsu rebadged here is a PDF of the Tohatsu manual which should help.http://www.tohatsu.com/tech_info/own_man_pdfs/Toh2-5A2_3-5A2_3-5B2.pdf

Yes, very good advice.

I've had the Yamaha 2B version (another clone of the same engine) for nearly 20 years, and have always run it on 50:1, instead of the specified 100:1.

Small two stroke outboards were often marketed as " 100:1 ", to keep up the competition between manufacturers boasts, ( similar to car oil change limits going up, sounds good, but not as good for the engine's long term life).

My Yamaha 2 and my Evinrude 4hp twin run very sweetly and cleanly on 50:1, and quite a bit cooler than when I tried them at 100:1.

That amount of extra lubrication will do no harm, and will undoubtedly result in less wear, especially if run at above half throttle, as Antares said...
