Abstract

La présente invention concerne un appareil de levage de moteur hors-bord qui peut modifier automatiquement la vitesse d'élévation et abaissement en fonction de l'état du moteur hors-bord. Un appareil de levage de moteur hors-bord (1) comprend : un premier passage d'huile qui relie une pompe (42), une seconde chambre d'un ou de multiples cylindres d'inclinaison (14) et une seconde chambre d'un ou de plusieurs cylindres d'habillage (12) ; un second passage d'huile relié à une première chambre d'au moins un desdits cylindres d'habillage ; une vanne de commutation (60) disposée sur le second passage d'huile ou entre la seconde chambre desdits cylindres d'inclinaison et la seconde chambre desdits cylindres d'habillage sur le premier passage d'huile ; et une unité de commande (100) conçue pour se référer à un signal d'état de coque et commander la vanne de commutation.
