Use a 50::1 fuel mix. That is 1 pt of TCW-III 2 cycle oil to 6 gal of gasoline.

Read the "How to awaken a sleeping outboard" sticky post under FAQ

as was said, ive read the FAQ version...its too widepspread..im looking for someone to tell me where the grease and oil points are, what are common problems with mercury 850's, ive searched the board and all i find is general info...sorry, im not trying to sound like an ***, but im no noob to forums, im on several forum boards, this one is my lowest post count by thousands, i know how to search....


can someone please tell me what to service?? i really need to find out what plugs go in it since the PO has no mechanical skills and just threw something in it...is the above mentioned 50:1 the proper fuel mix??

The only other thing that beats a forum in knowledge is a service manual......

The best investment I made for my merc.

There are grease fitings on the swivel bracket(1), tilt tube(1), PTT(2), tilt lock(1) and 2 on the dissy, if you have one. The steering cable also may have one.


Plugs may be looked up in the champion or NGK application guide. Plugs are either Champ L-76V or L-78V or NGK BUHW or BUHW-2, depending on year. All of these plugs are surface gap.
