ABSTRACT:
Provided is a trimming and stabilizing arrangement for motor-driven vessels of the type in which the engine of the vessel is placed in the stern thereof and comprises either an outboard engine or an inboard engine with an outboard drive, wherein the propeller driven by the engine is located beneath a holding device in the form of a fin, serving as a stabilizer, and wherein the steering of the vessel is effected by pivoting the propeller about a vertical axis. A plate is arranged to coact with the fin and extends over the propeller and beyond the propeller sternwardly of the vessel. The plate has a downwardly facing planar surface, the edges of which in the direction of movement of the vessel are curved downwardly. The holding device and plate comprise at least two parts, one of which co-acts with and embraces the motor leg of the engine immediately above the propeller, and the other part comprises a planar plate co-acting with the holding device via attachment apparatus.
