Fuel injected model , have the fault codes read
carby models have the entire fuel system cleaned out and all rubber hoses, pump diaphragm replaced as the hoses break down internally and put rubbish in the pump and carby's
do not use e-mix fuels as the ethanol absorbs moisture and that corrodes aluminium bits , rusts fuel tanks and breaks down the rubber components

I need the type and info on my Mercury Classic 50 outboard motor


serial number is what you need and try looking on the starter or the switch box ( square box with lots of wires on as they have dates on also ) take pictures of engine in and outside as if decals are original it will date it as well ! take to or email your nearest dealer with all info and they date your engine no problem !

Have 115 Hp mercury outboard motor missing at full throttle and on idle. At mid throttle it is running fine. Any Idea what the problem could be. Thanks, Milton


Have your spark plugs changed AND carbs cleaned and adjusted.
Usually that can also be caused by a seized advance system ( plate under the flywheel, commanded to turn with the throttle linkage... )
