    Hey Tom. The recommended "stage I" settings are 9-1-1-9. This is not a bad starting place. You need to use a tachometer to fine tune. Settings are from 1 (close) to 11 (open).

    #1-The Green fuel pot sets the engines fuel delivery idle to midrange cruising at constant throttle. Run this setting till the engine is warm and if it feels or smells "rich" back it down. I am at a 6 on the Green.

    #2-The Yellow fuel pot adds fuel on top of the Green when throttle is opened rapidly. Like an accelerator pump. With engine warm perform rolling WOTs and open till you get the most rpm gain or "flare" without stumble. One position at a time open the pot till you reach desired setting.
    I am at a 5 on the Yellow.

    #3-The Red fuel pot functions as your main metering circuit. Run the craft WOT and note the rpms. Opening the Red pot adds fuel. You dont have to go far with this one. Most boats run at the #1 setting. I am at 1 on the Red pot.

    #4-The RPM selector pot sets the RPMs at which the red(high) speed metering circuit takes over the green and yellow. You want this to go RED at approx 5500 rpms. For testing puposes, slowly accel engine until you see the Red pot light up and make small adjustments to achieve desired rpm setting. Note: 1 is supposed to equal 1000 rpms, 2-2000 rpms and so on. This is only a guide and may not be accurate. My high speed comes in about 5600 rpms and I am set at 7.

    Any questions...give me a call

    jusr goes to show that you have to tune to your specific application. experimenting with the efi settings is mandatory to get the best possible combination for your particular setup
