Re: Fuel economizer setup for Johnson 35HPs adapted to 25HP?

[mr-asa]

quote FrankR:

The theory behind the fuel saver is that you bring the boat up on plane at full throttle, then back off on the throttle to the "cruise" position. That keeps the spark at full advance but partially closes the carburetor butterfly, presumably saving some gas. It works somewhat on a boat with adequate power. But if the motor struggles to maintain speed at WOT, then backing off to cruise throttle will lose the plane.

Interesting, considering I’m planning on running my 25HP on my Herter’s and everyone looks at me like I’m mildly crazy for doing so, hopefully there won’t be an issue with losing plane. Of course, I haven’t even got it water worthy yet.

I’m in no hurry.
