8LV Series Operation Manual
There are two types of special service tools for
removing the impeller:
The seawater pump turns counterclockwise as
viewed from the side cover, so the impeller must be
installed as shown in Figure 8. If the impeller has
been removed it must be installed in the correct
direction. Additionally, if the engine is being turned
over manually, be careful to turn it in the correct
direction. Incorrect turning will twist the impeller
blades and cause damage.
