Check plug wire first-- replace if bad. See if contact in plug cap is corroded. Use some Dielectric Contact Grease in the spark plug cap-- this will ensure good contact.

Also check kill wires that travel to tiller. They often get broken internally or get shorted out as they enter the housing engine.

These are the most obvious and easiest to fix. Your intermittent probem sounds like one of these issues (I used to have this same engine and had both problems)

SOURCE: mercury outboard over charging

Your motor is fine. It needs to put out more than 12 volts or the battery will not charge. Most alternators put out between 13 - 17 volts, so this is well within the range.

Mercury outboard problems


Is this a two stroke?-If it is you most likely have a primary seal going bad (crankcase seal on the ignition side will lean it out,leaking seal on the other-side of assembly will do just what your describing)Hope this helps you out.....

1976 115 hp mercury outboard motor manual


fuel goes in at connector then to fuel pump then to carbs ! remove connector off fuel line and prime fuel up so you know you got fuel ! then reconnect to engine and prime up again till you see filter filling and bulb should harden , then remove a drain screw from carb bowl and prime again and see if fuel comes out of all carb drains ! if yes then start engine with or in water with kill lanyard on if ok then good ! not then check sparks on all plugs putting them against the head for earth and crank to check ! if ok then i would remove carbs and clean the jets etc ! compressions 100psi or more on all cylinders ! less means recon pistons etc !

Water pump


The water pump is a flexible impellor located in the top of the bottom section of the leg of the outboard. It is driven by the drive shaft to the prop that is spinning all the time the motor is running. You will find it behind or near the water inlet slots at the bottom of the leg
