Hello. My name is Tan.

The throttle does have some area in the throttle that doesn't advance throttle. This is so you can put the engine in gear before it gives you throttle. This is to prevent the boat lunging forward.

Now as for the low on power we need to do a compression test.

Have you changed all the fuel filters? There is one in the carburetor and the fuel pump. When was the last time you had the engine tuned up?
