If it is a 250 SHO like mine. Take the cowling off and on the starboard side of the engine is a round metal pulley that the throttle cable is attached to. If you look at this round metal pulley there is a mark that lines up with a mark above it when the throttle or hotfoot is wide open. The throttle does not have a stop on the engine it will go past wide open, you must line these marks up when your hotfoot is down against the stop bolt. If the marks do not line up use the stop bolt behind the hotfoot to line the marks up when the hotfoot is fully compressed.Mine was opening completely when it was delivered.Tom
