(8) Model HC-D2MV20-3 only:
(a) Rotate the blades by hand toward low pitch until the
jack plate contacts the spacer ring. Confirm that there
is a minimum of 0.025 inch (0.63 mm) clearance
between each clamp and the valve.
(b) If there is insufficient clearance between the clamps
and the valve, measure the gap to determine how
much clearance is needed. Remove and reassemble
the propeller in accordance with this chapter, using
the alternate spacer ring that will provide adequate
clearance.
1 Refer to Table 3-3 for reverse blade angle changes
that will result from the installation of alternate
spacer rings.
2 Remove the propeller in accordance with the
propeller removal instructions in this chapter.
