Re: Help with timing

If you have a vacuum advance yes it will, it will also affect you idle which will give you a different RPM and that will throw it off also

Re: Help with timing

boats DO NOT have vacuum advances. if you have a vacuum leak, you have an air/fuel ratio issue, it will affect your performance.

Marine distributors do not have vacuum advances, and no, vacuum leaks will not change timing.
