Checking Power Tilt Fluid; Submerged Outboard - Mercury 9.9 BigFoot Manual

Checking Power Tilt Fluid

1. Tilt outboard to the full up position and engage the tilt lock
lever.
2. Remove fill cap and check fluid level. The fluid level should
be even with the bottom of the fill hole. Add Quicksilver or
Mercury Precision Lubricants Power Trim & Steering Fluid. If
not available, use automotive (ATF) automatic transmission
fluid.

Submerged Outboard

A submerged outboard will require service within a few hours by
an authorized dealer once the outboard is recovered from the
water. This immediate attention by a servicing dealer is
necessary once the engine is exposed to the atmosphere to
minimize internal corrosion damage to the engine.
