90-830234R3 DECEMBER 1997 MID-SECTION - 5C-17
Shock Function Return
After the engine clears the under water object, the
weight of the engine will increase the oil pressure be-
tween the memory piston (t) and shock piston (u) to
the level required to open the shock return valve (h),
inside the shock piston, allowing the oil to bleed back
through the shock piston into the down cavity. If re-
quired, additional oil will enter the down cavity
through the manifold reverse suction valve (o). This
will return the engine back against the memory piston
(t) and into the original running position.
