Welcome aboard.

Moved this from the Electrical section because it's a motor question. In 1965, Chrysler was in the 2nd year of making Sea Kings and the model number starting with VWB says this is a Chrysler made motor. So you're in the Chrysler/Force section now.

Don't know anything about Chrysler Sea Kings, but for most motors, point gap is set when the cam lobe is on the high point and the points are fully open. Then you adjust the gap.

Hope that's what you are looking for.

There is a Manual showing at the address below that might show the Info, Mark and More. Plus, plenty other info if you search, ?how to set the points timing on 35 hp Chrysler Outboard Motor?.

I feel there could be a ?Index Mark? at the Cam?s highest per my Clymer Manual and my 1970 35hp Chrysler Motor.

As stated the mark is probably at the highest point of the cam lob that open the points. The new or cleaned points gap is.020 with a feeler gauge. My experience was never a timing issue vs points got dirty, ?from too much oil on the cam lob wick?.

railman, :welcome: aboard to iboats. Nice to have you join us...

Points are usually set at the highest point of the lobe on the crankshaft as it turns. The time the points are closed is called "Dwell Time". And the spark occurs when the points open. So set the points at the highest point and usually that is set at 0.020". But verify that before setting them. Chrysler OB engines could have used something different. I've never worked on one of them myself. The condensers are there to keep spark from jumping across the points as they open. That protects the points from burning. And that is a standard point and condenser ignition system minus the exciter coil (if it has one) and actual spark coil and the spark plug. JMHO!
