Power Trim Fluid
Power trim fl uid allows your stern drive to angle up or down. This is
particularly useful when trying to get your boat to plane where the hull
is as much out of the water as physically possible, reducing friction,
and improving ride performance. This power trim fl uid is used in
hydraulic rams that maneuver the stern drive unit, and shouldn’t need
to be replaced very often, if at all.
Power trim fl uid should be checked regularly, despite not requiring
replacement unless something serious happens. Discoloration or
water presence indicates a water leak in the stern drive. In that case,
contact your Regal dealer.

Shaft Lubricant
Drive and prop shaft lubricant keeps the turning parts on the
propshaft from wearing out too quickly. It also assists in the removal
of the props by preventing the metal parts from binding. Lubricant
should be placed on the u-joint and spline shaft, along with an anti-
corrosive grease to ensure continued functionality. Consider having
the shafts serviced periodically to ensure proper lubrication at the
engine coupler and propeller.
