need some info on a old seahorse

[daleyboy]

I have a 1963 75 horse johnson v-4 outboard that i,m working on. I was wondering if somebody could tell me the firing order,and the timing.

Being an old seahorse myself, I thought I might answer this post.

The firing order is easy, 1 2 3 4.

The timing is set first by the marks lined up with the flywheel and crankcase, the the distributor or magneto pulley notch or color and the bracket mark or the safety switch. You will need a service manual for the exact markings on the engine, as they varied with the models and years.

The proper adjustment and synchronization between the throttle, carb, and spark adv linkage took care of the engine timing.

Here's some photos of the timing marks on my 64 Evinrude. They should be the same as yours. If all four don't line up then you need to loosen the belt and move it a notch or two. Worst case scenario, the flywheel key has sheared and it's not in the correct position.

Oh, by the way, which one is the #1 cylinder

If it is the 1963 Electric shift 75 with 20amp alternator, it's different than that. The 20 amp flywheel looks like a flying saucer with round windows all around it.

top stb. side.

Look at the plugs, #1 is the highest(stb. side), #2 is next highest (port side), etc. etc.

My cylinders are numbered as well as the plug wires.
Are you having problems getting your Johnson to run? The timing doesn't usually need adjustment, it's usually the link & sync.

The outboard actually belongs to a friend of mine. He has a tank hooked up to it in his yard, and has tried to start it. All he has been able to do is get it to pop a couple of times.Somebody else had been messing around with it so he the firing order was wrong.I,m going over there today and check it out. I,ll keep the progress posted

Yep, it,s a electramatic, and the numbers on the cylinders are not the same as the previous pictures. on the strb side the cylinder# is 2 at the top,would it still be the same firing order?By the way, that flywheel does look like a UFO with porthole windows all around it.

Send me your e-mail address in a PM and I'll send you the timing instructions for that one.
