Several embodiments of automatic trim controls for marine outboard drives for maintaining the optimum trim angle under all running conditions. The velocity of the watercraft is determined and the outboard drive is trimmed up as long as the velocity continues to increase and then is trimmed down so as to maintain the hi...
Disclosed are embodiments of a marine vibrator and methods of using. Embodiments of the marine vibrator may comprise a containment housing; a piston plate, wherein an internal volume of the marine vibrator is at least partially defined by the containment housing and the piston plate, the internal volume containing a fi...
The marine fire-control system preferably comprises several subsystems, each having a target detection module and at least one effector module. The subsystems and/or the modules are extensively interlinked and contain means for compensating static, quasi-static and dynamic alignment errors. By means of at least one com...
A number of embodiments of feedback control systems for maintaining the desired air fuel ratio in a marine propulsion engine that has an exhaust system for exhausting the exhaust gases to the atmosphere through an underwater exhaust gas discharge and wherein the discharge is adjustable relative to the associated waterc...
In a marine fender with a structure for fixing a pad to a fender frame, the pad has at least one concavity formed in a front surface thereof, and a pad hole piercing the pad from a bottom of the concavity. A bolt with a head is inserted from a front side of the pad through the pad and fender holes, and a nut is dispose...
