A trim position indicator for outboard motors or the like for determining the tilt or angularity of the propeller with respect to a parallel position to the water level. The indicator is attached to the motor shroud to give an indication of the angle between the axis of the motor propeller and the water surface. When the motor is tilted, e.g. as the boat comes up to planing speed, the trim position indicator indicates the angular degree of tilt by means of a float therein which no longer is centered between two indicator markings. Consequently, appropriate trimming measures may be taken so that maximum propulsion is restored. The sensing member may be in the form of an air or light gas filled spherical float which, due to the higher specific gravity of the liquid surrounding it, seeks the highest point within the arc shaped level. Methods of mounting the trim position indicator on outboard boat motors both with and without hydrofoil stabilizers are also provided.

A trim position indicator for mounting on the cover of a boat motor having a propeller with a propeller shaft, for use in water having a surface, said trim position indicator being characterized by its indicating the relative angle between the propeller shaft and the surface of the water, said trim position indicator comprising: a) a closed transparent tube having a first end having a first sticky mounting base, and a second end having a second sticky mounting base, said sticky mounting bases being for mounting said transparent tube on said cover, said transparent tube having a given shape and at least one wall having an inner surface and an outer surface, said inner surface of said wall having an upper portion and a lower portion, said inner surface defining a space within said tube; b) a substantially spherical float having a predetermined specific gravity disposed within said transparent tube; and c) a liquid filling the space in the tube around said spherical float, said liquid having a specific gravity greater than the specific gravity of said float.
