ABSTRACT:
A weed deflector (28) is provided by a bar (30) mounted to the driveshaft housing (12) of a marine drive (10). The bar (30) has a top portion (46) extending forwardly from the driveshaft housing (12) to a forward leading tip (32) and has a lower portion (38) bent downwardly and rearwardly and tapered back to and mounted to the driveshaft housing (12). The space (34) between the forward leading tip (32) and the driveshaft housing (12) is open so that it does not affect steering of the marine drive (10). The tapered portion (38) of the bar (30) forces weeds to slide downwardly and rearwardly therealong and off of the driveshaft housing (12). The bar (30) prevents weeds from wrapping around the strut portion (14) and covering cooling water inlets (20) or interfering with the propeller (22) or propeller efficiency.
