the 120V AC battery charger (see chapter 4, Electrical Systems).
Check each battery cell, making sure the electrolyte levels meet the recommen -
dations in chapter 7.

Before beginning, be sure to install the propellers on the correct shafts. If they
are installed on the wrong shafts, the boat will move in reverse when shifted
into forward.
To install the propellers (
Figure 6-1
):
1. Remove adhesive tape, jam nuts and cotter pin from the propeller end of
the shaft.
2. Remove adhesive tape and pull the key out of the keyway.
3. Clean the shaft end, especially the tapered surfaces, to remove all for
-
eign material.
4. Clean the internal taper of the propeller hub. Check for burrs or machin -
ing imperfections. Deburr and correct any imperfections.
5. If lap fitting the propellers is desired, execute it at this time.
6. With key removed, install the propeller on the shaft. By hand, push the
propeller onto the shaft until it is seated on the taper. With a fine point
marker such as a Sharpie
®
, mark the location of the forward end of the
propeller hub on the shaft.
7. Remove the propeller.
