Seacock Size Recommendation
Seacock used must have an internal cross-sectional area equal to
or greater than hose to prevent restricting waterflow. Install valve in
an area where it will be easily accessible and supported adequately
to prevent hose fatigue. A 1-1/4 in. (32 mm) brass ball or gate valve
is suggested.

Crankcase Oil
To help obtain optimum engine performance and to provide
maximum protection, we strongly recommend the use of Quicksilver
4-Cycle 25W-40 Marine Engine Oil. This oil is a special blend of
25-weight and 40-weight oils for marine engines. If not available, a
good grade, straight weight, detergent automotive oil of correct
viscosity, with an API classification of SH, CF/CF-2, may be used.
In those areas where Quicksilver 4-Cycle 25W-40 Marine Engine Oil
or a recommended straight weight oil are not available, a
multi-viscosity 20W-40 or, as a second but less preferable choice,
20W-50, with API service ratings of SH, CF/CF-2 may be used.
