Timing for 60? 95 Evinrude 115?

[rexicon]

I've got the Seloc manual to mop up the oil spills but really need to know the timing specs for my new (to me) 95 'rude.

I'm something of a novice at the outboard game so here are my newbie questions to go along with the above.

- testing, under load or in neutral?
- what rpm's?
- can I use an automotive timing light? - got my handy Craftsman at the ready if yes!
- which plug wire do I attach to?

Thanks for any input and if I've missed any obvious questions please feel free to chip in.

this is the easiest way to time an J/E outboard. works very well and is easy.

(Timing At Cranking Speed 4?)
(J. Reeves)

NOTE: If your engine has the "Fast Start" feature", you must disconnect/eliminate that feature in order to use the following method. The "Fast Start" automatically advances the spark electronically when the engine first starts, dropping it to normal when the engine reaches a certain temperature.

The full spark advance can be adjusted without have the engine running at near full throttle as follows.

To set the timing on that engine, have the s/plugs out, and have the throttle at full, set that timer base under the flywheel tight against the rubber stop on the end of the full spark timer advance stop screw (wire it against that stop if necessary).

Rig a spark tester and have the gap set to 7/16". Hook up the timing light to the #1 plug wire. Crank the engine over and set the spark advance to 4? less than what the engine calls for.

I don't know the full spark advance setting your engine calls for, but to pick a figure, say your engine calls for 28?, set the timing at 24?. The reasoning for the 4? difference is that when the engine is actually running, due to the nature of the solid state ignition componets, the engine gains the extra 4?.

If you set the engine to its true setting at cranking speed, when running it will advance beyond its limit by 4? which will set up pre-ignition causing guaranteed piston damage! You don't want that to take place.

No need to be concerned about the idle timing as that will take care of itself. The main concern is the full advance setting.

Be sure to use your own engines spark advance settings, not the one I picked out of the air here in my notes.

Thanks for that!

Next up - what should the advance be at WOT and how do I disconnect the fast-start for the purposes of this?

Bump for anyone that knows how to disconnect the fast-start circuit. I'm obviously going to have to pony up for an OEM manual to find the timing specs.

thanks
