To provide a marine gear device which inhibits vibration and noise of clutches at the time of trolling.SOLUTION: A marine gear device 8 comprises a forward and backward switching mechanism 17 having a forward clutch and a backward clutch 15 which transmits rotational power of an engine 7 installed in a ship 1 to a propeller 5, and a trolling device 25 which adjusts hydraulic fluid pressure toward the forward and backward switching mechanism 17. The marine gear device 8 is composed in a forward two speed type that forward power of the forward and backward switching mechanism 17 switches standard speed and large deceleration, and comprises a standard speed side clutch 14 and a large deceleration side clutch 16 as forward clutches, and is composed so that both of the standard speed side clutch 14 and the large deceleration side clutch 16 do slip coupling at the time of trolling.SELECTED DRAWING: Figure 8

    【課題】トローリング時におけるクラッチの振動や騒音を抑制する。【解決手段】マリンギヤ装置8は、船舶1に搭載したエンジン7の回転動力をプロペラ5に伝達する前進クラッチ及び後進クラッチ15を有する前後進切換機構17と、前後進切換機構17に向かう作動油圧を調節するトローリング装置25を備える。マリンギヤ装置8は、前後進切換機構17の前進出力を標準速と大減速の前進2速式に構成し、前進クラッチとして、標準速側クラッチ14と大減速側クラッチ16を備え、トローリング時には標準速側クラッチ14と大減速側クラッチ16の両方をスリップ係合させるように構成している。【選択図】図8
