• a main body disposed on the back side of the hull board for transforming rotational movement of said operating lever into operation force on a control cable, said main body having a shaft connected with said operating lever for transmitting movement of said operating lever and a plurality of first installation holes arranged in a first pitch circle radially about said shaft;
• and
• a set block installed on the fore side of the hull board for fixing said main body to the hull board, said set block having a slit for receiving said shaft in the lateral direction during installation and a plurality of second installation holes arranged in a second pitch circle having the same diameter as the first pitch circle of said first installation holes with at least some of said second installation holes aligned with said first installation holes when said shaft is received in said slit.
