I have a '92 70 horse. I'm reading where it says to rig a spark plug tester and have the gap set at 7/16". I have one, but do I need three? It says to "have the s/plugs out". If I only need the one then what would I do with the other two spark plug boots?

Re: Question about J. Reeves WOT timing procedure

You either need to make a simple three-way tester, or test each plug/wire separately with your tester with the others grounded to the block.

Re: Question about J. Reeves WOT timing procedure

just ground them or let em hang .
ive done both and never had any probs.
just make sure you are turning over fast enough.
and that timer base is pulled forward
then subtract 4 degrees from your motors timeing spec and you will be close .
i do joes method to get running and synced.then time it in the water,later
of the last three i have checked was very close works good .

Re: Question about J. Reeves WOT timing procedure

Just an after thought, but how does one do WOT timing in the water? Timing light doesn't seem to be bright enough and is the boat strapped to the trailer? I've never done it.

Re: Question about J. Reeves WOT timing procedure

with Joes procedure, you can set it with out the motor running, then just recheck, and don't do it on a trailer.

A nice line of white paint on the flywheel at the degree your shooting for will be visible in the light.

Re: Question about J. Reeves WOT timing procedure

hey guys.............:D:Di need a volunteer to hang off the back of my boat for the fine tunning of the timing..........any takers..........i promise if you fall out ill come and get you......but the water temp out there was 48f today, pretty chilly for a swim:eek::eek.

is there a different way to "fine tune" without this daring attempt?you know like if it was cold or you dont trust your joker buddies not to try and lose you.

Re: Question about J. Reeves WOT timing procedure

See, that's what I'm talkin' about! I'm I suppose to be WOT across the pass hangin' on with a timing light? If I'm lucky I'll just fall in, if I'm not lucky, i'll just fall into the fly wheel! OUCH!!!
If that's the deal i'll do it but I would like to here it from others.

Re: Question about J. Reeves WOT timing procedure

i think you missed reading one line. this is the reason for these directions.

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

So than I'll set it and forget it. No need to tweek it in the water, it'll be good to go if I follow Joe's procedure. I'll give it a shot. Thanks Tash.

Use liquid paper, it works great and is very convenient.

Re: Question about J. Reeves WOT timing procedure

while this procedure is common,...esp,after an overhaul,etc,to get close,....it is far from a professional way of doing a critical component in an outboard..
Wide open timing,is set on a dyno,..or in a test tank,with a test wheel installed,....or hanging off the back,hoping u dont hit a big wave....i have had to do all 3.
I suggest,if u dont have a way to set the timing accurately,take it in to a shop,...this should always be done during a professional tune up.
Timing is critical for engine longevity,and to get the correct performance out of it,.....safely.

Re: Question about J. Reeves WOT timing procedure

well if a man with over 30 years of experience with OMC motors recommends it, and it does work, i will keep following Joe's advice. sure there are exceptions, usually when something else is wrong also.

Re: Question about J. Reeves WOT timing procedure

i have used joes method on my last three v6 rebuilds
two of the three were almost dead on. the last being 3degrees off
tested in tank .i use his method to get running then i take to ad old evinrude guy i use and he tanks it and double checks my link and synk
the method is the only safe way to time without tank to get running but finale adjustment under load may vary enough to hurt anything i dont know but my evinrude guy says static timeing is fine but he always tanks or dynos.
and ive tyed mine to trailer and checked works fine but i dont suggest .
you can have it tanked in my area for 65 dollars
but i have a 50 and a 35 that i used joes method on and have never had prob and have not checked in water for three years now ,but with the 6 cylinders i dont wont to lose another powerhead so i have it tanked after joes method

Re: Question about J. Reeves WOT timing procedure

i did mine joes way and it ended up being 1deg off thats why i thought it was for the initial set up (like after an overhaul or ignition component replacement)so you didnt kill anything.


i did check mine on the water thats why i said it was 1 deg off but that could have been human error on my part.


if i were to do it again i would want to do it when the water was a little warmer.

I completely agree. I set the timing on my 1988 Johnson 110 this summer using Joe's method but I wanted to be absolutely sure that it was right. headed out onto lake with timing light in hand and 11 year old son at the helm at WOT and it was "Bang on". Liquid paper on the timing mark will show up in broad daylight as suggested.

Re: Question about J. Reeves WOT timing procedure

Here's the deal, it worked for me! I did the whole sync & lync, did the timing pointer adjustment turning the flywheel twice and splitting the difference between the "A" and "B" mark, it was right at TDC. I removed the plugs, installed spark testers in all three holes set to 7/16", timing light on top cylinder, WOT set, painted my mark on the flywheel(4 degrees less), jumped across the starter with a screwdriver and my mark was right on. That's about the only right with this boat as I have an overheat problem which is in another post.
