  • Patent number: 11814993
    Abstract: A method for checking the oil level in a marine drive unit, where the drive unit is provided with an external oil filter, an oil level sensor adapted to determine an oil level in the drive unit, and an electronically controlled tilt means, comprising the steps of, initiating an oil level check, controlling the tilt means to tilt the drive unit to a plurality of different tilt angle positions, for each tilt angle position, determining if the oil level sensor detects the oil level in the drive unit, for each tilt angle position, registering the tilt angle of the drive unit and the signal from the oil level sensor, determining at which tilt angles the sensor detects the oil level, and in dependence of the determined tilt angle of the drive unit, determining if the oil level of the drive unit is within a predefined range.

  • Publication number: 20220126953
    Abstract: The invention relates to a platform arrangement (110) mounted to a stern portion of a marine vessel (100). The platform arrangement comprises at least one first platform section (111) with a first transverse pivot joint (113) mounted adjacent a transom (105); at least one propulsion unit (101) mounted to a lower surface of the first platform section (111), wherein the at least one propulsion unit (101) and its first platform section (111) are tiltable between a drive position and an upwards tilted position. A second platform section (112) is located in front of the at least one first platform section (111), which second platform section (112) has a second transverse pivot joint (114) mounted adjoining the first transverse pivot joint (113) of a corresponding first platform section (111). The first and second platform sections (112) are foldable relative to each other about their respective first and second pivot joints (113; 114). The invention further relates to a vessel comprising the platform arrangement.
