Comments on the fuel saver adjustment.
With my 1957 35hp Johnson there seems to be a difference in how it runs and sounds in these two scenarios:
1) If I slowly advance the throttle until the boat is moving about 20 mph.
2) If I full throttle it and then back off of the throttle until the boat is moving about 20mph.
This motors sounds like it is under a lighter load if full throttled and then backed off. I believe there is a slightly different spark advance setting in the two scenarios. I’m not one that goes in for powerful ‘hole shots’ so often I creep up on the operating speed at which I want to cruise. Most often I do creep up to my desired cruising speed of 20mph and then give it a second or two of full throttle then back off. This motor seems much happier operated this way.
If anyone has an explanation of what I’m experiencing, I’m all ears. I’m into long cruises and the throttle may stay in the same setting for an hour or more and I can’t help but think there is a major difference in what is taking place inside of the motor.
