Baja Marine 275 manual Impact to Stern Drive, Propeller Removal and Installation

Section 4 • Bilge & Underwater Gear

C.Impact to Stern Drive

The stern drive can be damaged by impact, either while trailering or boating. To minimize the possibility of impact damage while trailering, keep the stern drive raised to the trailering position.

The hydraulic system used to raise and lower the stern drive can cushion impact and lessen damage from head-on impacts to the stern drive from underwater objects BUT ONLY when the boat is moving forward. There is no protection if the stern drive is struck during reverse operation or from an angle when moving forward.

If you strike a submerged object, STOP THE ENGINE as soon as possible and examine the stern drive unit for damage. Even if no damage is visible, there could be internal problems or difficulty maneuvering. If you must use the boat after impact, run at the lowest speed possible.

D.Propeller Removal and Installation

d.Remove the propeller nut retainer, the thrust hub and the continuity washer (Figure 4.3.3) and put them in a secure place. Pull the propeller straight off the shaft. Remove the thrust washer that is behind the propeller. If the propeller is seized to the shaft and cannot be removed by hand, special tools are needed. Have the propeller removed by an authorized dealer or trained mechanic.
