Purging Air From the Engine Oil Reservoir
1. Loosen the fill cap on the engine oil reservoir.
2. Start the engine. Run the engine until all the air has been vented out of the reservoir
and oil starts to flow out of the reservoir. Re-tighten fill cap.

Trim In Stop Adjustment
Some outboard boats, particularly some bass boats, are built with a greater than normal
transom angle which will allow the outboard to be trimmed further “in” or “under”. This
greater trim “under” capability improves acceleration, reduces the angle and time spend
in a bow high boat attitude during planing off, and in some cases, may be necessary to
plane off a boat with aft live wells (given the variety of available propellers and height
range of engine installations).
However, once on plane, the engine should be trimmed to a more intermediate position
to avoid a bow-down planing condition called “plowing”. Plowing can cause “bow steering”
or “over steering” and inefficiently consumes horsepower. In this condition, if attempting
a turn or encountering a diagonal, moderate wake, a more abrupt turn than intended may
result.
In rare circumstances, the owner may decide to limit the trim under. This can be accom-
plished by purchasing a stainless steel tilt pin (P/N 17-49930A1) and inserting it through
whatever pin hole is desired. The non-stainless steel shipping bolt should not be used in
this application other than on a temporary basis.
WARNING
Avoid possible serious injury or death. Adjust outboard to an intermediate trim
position as soon as boat is on plane to avoid possible ejection due to boat spin-
out. Do not attempt to turn boat when engine is trimmed extremely under or in.
