Default Twin 4.3 carburetor cable ? 2800SCR

After I set the boat on plane reaching 3500 RPM, then I try to adjust the engine rpm, adjust the trim taps, adjust the outdrive level , but the problem on my starboard side is that I move the throttle level down and feel like it is getting stuck and then suddenly something move or jump at the level box and goes down to 1000 or 800 RPM and it is not smooth the transition, I do not have any problem to increase the RPM, both carburetor are new . I replace them last year for other reason and the problem existed with the old carburetor, I greased the cable going to the throttle and the problem still there.. maybe the Mercury throttle level box ? I do not have any problem to switch back and forward at all, it is just to lower the rpm only on the starboard side
I was thinking to replace the cable , but need to get P/N for it and or check if there is anything loose inside the throttle box.. checking here for ideas...

Thank you in advance,

Jose Maracucho

Most likely the cables core is binding due to a worn jacket. I would replace the cable. The part number is on the outer jacket.
