ABSTRACT:
The invention pertains to a theft preventive installation on a boat. Particularly, it is directed to prevent a theft of the drive for the boat at its connection to a housing containing the drive shaft from the motor. It is commonly known that up to six bolts connect the drive to the housing. This particular connection is prone to be broken by unscrewing the bolts whereby the drive can easily be removed from the housing and thereby from the boat. According to the invention, the view of the bolts is obstructed whereby any application of tools to the bolts is prevented. In most installations, there are four bolts placed in a pattern with two bolts each on each side of the upper section of the drive. A plate having inwardly facing flanges thereon is placed under the bolts of each side of the drive. This will securely fasten the plates under the bolts. A third plate having a three-dimensional shape is placed over the ends of the two plates and is spanning the distance between the two plates, A lock bolt passes through the two plates and parts of the third plate. This then prevents the bolts from being viewed and any tools from being applied to the bolts or nuts on the bolts.
